When AC power is supplied to the motor, a built-in rectifier energizes the brake coil, creating an electromagnetic force that pulls the armature plate away from the brake disc against spring pressure. The brake releases and the motor runs freely.<\/p>\n<p style=\"margin: 0 0 14px;\">When power is disconnected, the electromagnetic field collapses and compression springs immediately push the armature plate against the brake disc, applying friction torque that brings the rotor to a complete stop. This fail-safe spring-applied, electrically-released design ensures the motor stops and holds position even during power failure, making it suitable for vertical lifting applications where load slippage could cause injury or equipment damage.<\/p>\n<p style=\"margin: 0 0 14px;\">Our brake motors are manufactured with the same stator and rotor technology as our <a style=\"color: #00a8cc; text-decoration: none; font-weight: 600;\" href=\"https:\/\/industrialelectricmotor.net\/zh\/product-category\/three-phase-induction-motors\/\">standard three-phase induction motors<\/a>, ensuring consistent electrical performance while adding the braking function. The brake mechanism adds only 50\u201380 mm to the overall motor length depending on frame size.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" style=\"width: 100%; height: auto; border-radius: 10px; box-shadow: 0 4px 20px rgba(0,0,0,0.08);\" src=\"https:\/\/industrialelectricmotor.net\/wp-content\/uploads\/2026\/07\/cat-brake-motor.webp\" alt=\"Electromagnetic Brake Motor YEJ Y2EJ Series Three-Phase Korea Ever-Power\" width=\"600\" height=\"600\" title=\"\"><\/p>\n<\/div>\n<\/div>\n<h2 style=\"font-size: 26px; font-weight: bold; color: #1a3a6b; margin: 40px 0 20px; padding-bottom: 10px; border-bottom: 3px solid #E8A020;\">Technical Specifications<\/h2>\n<p style=\"margin: 0 0 16px;\">The following table lists the key engineering parameters for our YEJ\/Y2EJ electromagnetic brake motor series.

The resulting magnetic field attracts the armature plate, compressing the brake springs and pulling the friction disc away from the braking surface. The rotor shaft is now free to rotate. The brake release occurs within 0.15 seconds of power application, allowing the motor to accelerate to rated speed without drag.<\/p>\n<\/div>\n<div style=\"flex: 1 1 340px; min-width: 280px; background: #F5F7FA; padding: 24px; border-radius: 8px; border-left: 4px solid #00A8CC;\">\n<h3 style=\"font-size: 17px; font-weight: bold; color: #1a3a6b; margin: 0 0 10px;\">Motor Stopping (Brake Engaged)<\/h3>\n<p style=\"font-size: 14px; color: #374151; margin: 0;\">When power is disconnected, the electromagnetic field collapses immediately. The pre-loaded compression springs force the armature plate against the brake disc, generating friction torque that decelerates the rotor to a complete stop. This spring-applied braking action is entirely mechanical after power loss, providing a true fail-safe function. The motor will hold position under static load indefinitely without electrical power, which is critical for crane hoists and vertical lift applications.<\/p>\n<\/div>\n<div style=\"flex: 1 1 340px; min-width: 280px; background: #F5F7FA; padding: 24px; border-radius: 8px; border-left: 4px solid #00A8CC;\">\n<h3 style=\"font-size: 17px; font-weight: bold; color: #1a3a6b; margin: 0 0 10px;\">Manual Release Function<\/h3>\n<p style=\"font-size: 14px; color: #374151; margin: 0;\">Every Korea Ever-Power brake motor includes a hand-release lever accessible from outside the motor housing. During a power failure, this lever allows maintenance personnel to manually disengage the brake springs, freeing the shaft for manual repositioning of the load. This feature is required by safety regulations for overhead crane and hoist applications. The manual release is spring-loaded and automatically re-engages when released by the operator.<\/p>\n<\/div>\n<\/div>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-54\" src=\"https:\/\/industrialelectricmotor.net\/wp-content\/uploads\/2026\/07\/adv-custom-oem.webp\" alt=\"adv-custom-oem\" width=\"1448\" height=\"1086\" title=\"\" srcset=\"https:\/\/industrialelectricmotor.net\/wp-content\/uploads\/2026\/07\/adv-custom-oem.webp 1448w, https:\/\/industrialelectricmotor.net\/wp-content\/uploads\/2026\/07\/adv-custom-oem-1280x960.webp 1280w, https:\/\/industrialelectricmotor.net\/wp-content\/uploads\/2026\/07\/adv-custom-oem-980x735.webp 980w, https:\/\/industrialelectricmotor.net\/wp-content\/uploads\/2026\/07\/adv-custom-oem-480x360.webp 480w\" sizes=\"auto, (min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 1448px, 100vw\" \/><\/p>\n<h2 style=\"font-size: 26px; font-weight: bold; color: #1a3a6b; margin: 50px 0 20px; padding-bottom: 10px; border-bottom: 3px solid #E8A020;\">Features and Engineering Advantages<\/h2>\n<div style=\"display: flex; flex-wrap: wrap; gap: 20px; margin: 0 0 30px;\">\n<div style=\"flex: 1 1 320px; min-width: 280px; background: #F5F7FA; padding: 22px; border-radius: 8px; border-left: 4px solid #E8A020;\">\n<h3 style=\"font-size: 16px; font-weight: bold; color: #1a3a6b; margin: 0 0 8px;\">Fast and Repeatable Braking<\/h3>\n<p style=\"font-size: 14px; color: #374151; margin: 0;\">Braking response time is under 0.1 seconds at no load and under 0.25 seconds at full load for frame sizes up to 200L.

When power is removed, springs apply the brake automatically to stop and hold the shaft. When power is supplied, the electromagnet releases the brake to allow free rotation. This fail-safe design ensures the motor stops even during unexpected power loss.<\/p>\n<\/div>\n<div style=\"margin: 0 0 14px; background: #fff; border: 1px solid #e5e7eb; border-radius: 6px; padding: 18px 22px;\">\n<h3 style=\"font-size: 16px; font-weight: bold; color: #1a3a6b; margin: 0 0 8px;\">What is the difference between a brake motor and a standard motor with an external brake?<\/h3>\n<p style=\"font-size: 14px; color: #374151; margin: 0;\">A brake motor integrates the brake mechanism directly into the motor housing as a factory-assembled unit. This provides a more compact installation, factory-calibrated brake torque, and properly matched electrical connections. An external brake added to a standard motor requires a separate mounting adapter, independent wiring, and manual torque adjustment, resulting in a longer assembly and higher overall cost.<\/p>\n<\/div>\n<div style=\"margin: 0 0 14px; background: #fff; border: 1px solid #e5e7eb; border-radius: 6px; padding: 18px 22px;\">\n<h3 style=\"font-size: 16px; font-weight: bold; color: #1a3a6b; margin: 0 0 8px;\">Can a brake motor be used with a variable frequency drive?<\/h3>\n<p style=\"font-size: 14px; color: #374151; margin: 0;\">Yes, but with a specific wiring requirement. The brake coil must not be powered from the VFD output. Instead, connect the brake rectifier to a separate AC contactor or use an independent DC power supply for the brake.

For vertical lifting applications (hoists, elevators), calculate the gravitational torque of the maximum suspended load at the drum radius and multiply by a safety factor of at least 1.5 per EN 60204-32. Always select a brake torque equal to or greater than the calculated value.<\/p>\n<\/div>\n<div style=\"margin: 0 0 14px; background: #fff; border: 1px solid #e5e7eb; border-radius: 6px; padding: 18px 22px;\">\n<h3 style=\"font-size: 16px; font-weight: bold; color: #1a3a6b; margin: 0 0 8px;\">How long does the brake disc last?<\/h3>\n<p style=\"font-size: 14px; color: #374151; margin: 0;\">The brake friction disc is rated for a minimum of 1,000,000 operations under rated torque conditions. Actual service life depends on the inertia of the driven load, motor speed at the moment of braking, and the braking frequency. For applications with high braking frequency (more than 120 cycles per hour), disc life may be reduced and should be monitored through regular thickness measurements.<\/p>\n<\/div>\n<div style=\"margin: 0 0 14px; background: #fff; border: 1px solid #e5e7eb; border-radius: 6px; padding: 18px 22px;\">\n<h3 style=\"font-size: 16px; font-weight: bold; color: #1a3a6b; margin: 0 0 8px;\">What happens if the brake disc wears out completely?<\/h3>\n<p style=\"font-size: 14px; color: #374151; margin: 0;\">As the brake disc wears, the air gap between the armature and electromagnet increases. When the gap exceeds the maximum allowable value (typically 0.8\u20131.2 mm), the electromagnetic force becomes insufficient to fully release the brake, causing the motor to run with increased drag and generating excessive heat. Most brake motors include a visible wear indicator that shows when the disc has reached its minimum allowable thickness and must be replaced.<\/p>\n<\/div>\n<div style=\"margin: 0 0 14px; background: #fff; border: 1px solid #e5e7eb; border-radius: 6px; padding: 18px 22px;\">\n<h3 style=\"font-size: 16px; font-weight: bold; color: #1a3a6b; margin: 0 0 8px;\">Can the brake torque be adjusted?<\/h3>\n<p style=\"font-size: 14px; color: #374151; margin: 0;\">The standard brake torque is factory-set and is not adjustable by the end user. If a different brake torque is required, specify the desired value at the time of ordering. We can supply brake motors with reduced or increased brake torque within the mechanical capacity of each frame size. For applications requiring variable brake torque, a separate proportional brake controller can be used with a DC-powered brake coil.<\/p>\n<\/div>\n<div style=\"margin: 0 0 14px; background: #fff; border: 1px solid #e5e7eb; border-radius: 6px; padding: 18px 22px;\">\n<h3 style=\"font-size: 16px; font-weight: bold; color: #1a3a6b; margin: 0 0 8px;\">Is the brake motor suitable for outdoor installation?<\/h3>\n<p style=\"font-size: 14px; color: #374151; margin: 0;\">Yes. Our YEJ brake motors are rated IP55, providing full dust protection and resistance to water jets from all directions. For installations exposed to heavy rain, direct sunlight, or corrosive atmospheres, we recommend adding a protective canopy and specifying the tropical moisture-resistant insulation option at the time of ordering.<\/p>\n<\/div>\n<div style=\"margin: 0 0 14px; background: #fff; border: 1px solid #e5e7eb; border-radius: 6px; padding: 18px 22px;\">\n<h3 style=\"font-size: 16px; font-weight: bold; color: #1a3a6b; margin: 0 0 8px;\">What is the lead time for brake motors?<\/h3>\n<p style=\"font-size: 14px; color: #374151; margin: 0;\">Standard YEJ brake motors in common frame sizes (80M through 160L) and 4-pole configuration are available with a lead time of 10 to 18 business days. Less common configurations (2-pole, 6-pole, 8-pole, or frame sizes above 200L) may require 25 to 35 days. <a style=\"color: #00a8cc; text-decoration: none;\" href=\"https:\/\/industrialelectricmotor.net\/zh\/contact-us\/\">Contact our sales team<\/a> for current stock availability and exact delivery dates for your specific requirements.<\/p>\n<\/div>\n<div style=\"margin: 0 0 14px; background: #fff; border: 1px solid #e5e7eb; border-radius: 6px; padding: 18px 22px;\">\n<h3 style=\"font-size: 16px; font-weight: bold; color: #1a3a6b; margin: 0 0 8px;\">Do you supply brake motors with IE3 efficiency?<\/h3>\n<p style=\"font-size: 14px; color: #374151; margin: 0;\">Yes. Our Y2EJ series brake motors are available with IE3 (Premium Efficiency) rated motor windings while retaining the same electromagnetic brake mechanism. The IE3 brake motor uses the same frame dimensions as the standard YEJ series, so it serves as a direct replacement in existing installations where updated efficiency regulations apply.<\/p>\n<\/div>\n<h2 style=\"font-size: 26px; font-weight: bold; color: #1a3a6b; margin: 50px 0 20px; padding-bottom: 10px; border-bottom: 3px solid #E8A020;\">Customer Experiences<\/h2>\n<div style=\"display: flex; flex-wrap: wrap; gap: 20px; margin: 0 0 30px;\">\n<div style=\"flex: 1 1 340px; min-width: 280px; background: #F5F7FA; padding: 22px; border-radius: 8px; border-left: 4px solid #E8A020;\">\n<p style=\"font-size: 14px; color: #374151; margin: 0 0 14px; font-style: italic;\">We installed 24 YEJ-132M-4 brake motors on our overhead bridge crane system across two warehouse buildings. The braking response has been consistent and reliable through over eight months of three-shift operation. The manual release levers were tested during our annual safety inspection and functioned correctly on every unit. Replacement cost was approximately 45% less than our previous European-brand brake motors.<\/p>\n<p style=\"font-size: 14px; font-weight: bold; color: #1a3a6b; margin: 0;\">David L., Facility Manager<\/p>\n<p style=\"font-size: 12px; color: #6b7280; margin: 0;\">Logistics Warehouse, Houston, Texas, USA<\/p>\n<\/div>\n<div style=\"flex: 1 1 340px; min-width: 280px; background: #F5F7FA; padding: 22px; border-radius: 8px; border-left: 4px solid #E8A020;\">\n<p style=\"font-size: 14px; color: #374151; margin: 0 0 14px; font-style: italic;\">Our packaging line runs 200 cycles per minute with each cycle requiring a motor start-stop. After 10 months, the YEJ-90L-4 brake motors show no measurable increase in braking time. The brake disc wear indicator still shows within the green zone. This level of durability at the price point was not something we expected from a non-European motor brand.<\/p>\n<p style=\"font-size: 14px; font-weight: bold; color: #1a3a6b; margin: 0;\">Anna G., Production Engineer<\/p>\n<p style=\"font-size: 12px; color: #6b7280; margin: 0;\">Consumer Goods Packaging, Warsaw, Poland<\/p>\n<\/div>\n<div style=\"flex: 1 1 340px; min-width: 280px; background: #F5F7FA; padding: 22px; border-radius: 8px; border-left: 4px solid #E8A020;\">\n<p style=\"font-size: 14px; color: #374151; margin: 0 0 14px; font-style: italic;\">We use YEJ-160M-4 motors on our construction material hoists. Each hoist carries up to 2,000 kg of bricks and mortar to the upper floors. The 150 N\u00b7m brake torque provides more than enough holding force with our calculated safety factor of 1.8. We have had zero incidents of load slippage across 16 units over a 14-month construction period.<\/p>\n<p style=\"font-size: 14px; font-weight: bold; color: #1a3a6b; margin: 0;\">Mahmoud S., Site Mechanical Engineer<\/p>\n<p style=\"font-size: 12px; color: #6b7280; margin: 0;\">Construction Group, Dubai, UAE<\/p>\n<\/div>\n<\/div>\n<div style=\"background: #FFF7E6; border: 1px solid #E8A020; border-radius: 6px; padding: 18px 22px; margin: 0 0 40px; font-size: 13px; color: #374151;\">\n<p style=\"margin: 0 0 6px; font-weight: bold; color: #1a3a6b;\">Important Technical Note<\/p>\n<p style=\"margin: 0;\">Brake torque values and braking times listed in this document are measured under standard test conditions (rated speed, no external load inertia, 380V 50Hz supply). Actual stopping distance and time depend on the total system inertia, motor speed at the moment of braking, and the mechanical efficiency of the drive train. For safety-critical lifting applications, always calculate the required brake torque based on the maximum suspended load and verify compliance with applicable safety standards (EN 60204-32, ISO 12100, or local crane regulations). All specifications conform to JB\/T 8680-2008, IEC 60034, and GB\/T 755 standards.<\/p>\n<\/div>\n<div style=\"background: linear-gradient(135deg,#1A3A6B 0%,#00A8CC 100%); border-radius: 10px; padding: 50px 40px; text-align: center; color: #fff; margin: 0 0 20px;\">\n<h2 style=\"font-size: 28px; font-weight: 800; margin: 0 0 14px; color: #fff;\">Need a Brake Motor Quotation?<\/h2>\n<p style=\"font-size: 16px; margin: 0 auto 28px; max-width: 550px; opacity: 0.92; line-height: 1.6;\">Send us your application details \u2014 motor power, brake torque, duty cycle, and mounting type \u2014 and we will provide a detailed quotation with technical datasheet within 24 hours.<\/p>\n<p><a style=\"display: inline-block; background: #fff; color: #1a3a6b; padding: 16px 42px; border-radius: 4px; text-decoration: none; font-weight: bold; font-size: 15px; text-transform: uppercase; letter-spacing: 0.8px;\" href=\"#contact\">Request a Free Quote<\/a><\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<div style=\"max-width: 1200px; margin: 0 auto; padding: 0 20px; width: 100%; font-family: Arial,Helvetica,sans-serif; color: #1a1a1a; line-height: 1.8; font-size: 16px;\">\n<div style=\"background: #F5F7FA; border-left: 4px solid #E8A020; padding: 22px 28px; border-radius: 0 6px 6px 0; margin: 10px 0 30px; font-size: 15px; color: #374151;\">Korea Ever-Power electromagnetic brake motors (YEJ\/Y2EJ series) integrate a DC-excited disc brake mechanism directly into a standard three-phase induction motor, enabling rapid stopping with braking response times under 0.1 seconds.
