High-Torque Low-Speed Brake Motor for Heavy Industrial Drives<\/h2>\n

The Y2EJ 6-pole brake motor runs at approximately 960 rpm, delivering 50% more shaft torque than a 4-pole motor of the same power rating at the same frame size. This inherently higher torque output means that a smaller gearbox reduction ratio is needed for a given load speed, reducing gearbox size, cost, and the number of gear stages between motor and load. In applications where load speed is in the range of 20 to 100 rpm, a 6-pole motor with a single-stage worm gearbox frequently achieves the required output without a two-stage gearbox assembly.<\/p>\n

The integral spring-applied DC electromagnetic brake operates identically to the 2-pole and 4-pole variants. Spring force holds the friction disc against the rotor hub at rest; DC current energises the electromagnet to release the brake when the motor starts. On power interruption, the brake engages in under 0.3 seconds, holding the load without external braking force. Brake torque is adjustable by modifying the spring preload, and the friction disc lining is field-replaceable.<\/p>\n

Frame sizes span 71M through 180L, covering 0.18 kW to 22 kW. All units carry IP54 protection, Class F insulation, and CE marking. The 6-pole variant is particularly common in gate and barrier drives, slow-speed agitators, and escalator auxiliary drives where 960 rpm provides the right balance between torque and operating speed.<\/p>\n

Typical Applications for Y2EJ 6-Pole Brake Motors<\/h2>\n\n\n\n
\"Y2EJ<\/p>\n
\n
Heavy-Duty Conveyors<\/div>\n
Bulk material handling conveyors and steep incline belt conveyors in mining and aggregate processing use the 6-pole brake motor to combine the high starting torque of a slow-speed winding with fail-safe brake holding against loaded belt rollback on power loss.<\/div>\n<\/div>\n<\/td>\n
\"Y2EJ<\/p>\n
\n
Large Agitators<\/div>\n
Top-entry agitators on chemical and pharmaceutical vessels use the 6-pole brake motor to hold the shaft and impeller stationary during vessel pressurisation, cleaning cycles, and maintenance, preventing rotation from residual fluid drag forces on the impeller.<\/div>\n<\/div>\n<\/td>\n
\"Y2EJ<\/p>\n
\n
Vertical Lifts and Gates<\/div>\n
Food processing vertical lifts, sluice gates, and dam control mechanisms use the 6-pole brake motor for its high torque and positive load holding, which prevents gate movement under hydraulic pressure when the motor is de-energised.<\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n
\n
\n
\u26f7<\/div>\n
Ski Lift Auxiliary Drives<\/div>\n
Haul rope tensioning systems and auxiliary bull-wheel drives on ski lifts use 6-pole brake motors for their low operating speed, high torque, and the mandatory fail-safe braking required under cable transport safety regulations.<\/div>\n<\/div>\n<\/td>\n
\n
\n
\ud83d\udd25<\/div>\n
Kiln Turning Gear<\/div>\n
Auxiliary turning gear motors on cement and lime rotary kilns use 6-pole brake motors to rotate the kiln shell slowly during cool-down, preventing thermal distortion of the shell. The brake holds the kiln in the rest position when turning is not required.<\/div>\n<\/div>\n<\/td>\n

\n
\ud83d\udea8<\/div>\n
Stage Curtain Drives<\/div>\n
Fire curtain and safety curtain drives in theatres and public buildings use 6-pole brake motors because their low speed and high torque allow direct drive of the winding drum without a multi-stage gearbox, and the fail-safe brake holds the curtain at the set position.<\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
\n

Torque Advantage of the 6-Pole Configuration in Brake Motor Applications<\/h2>\n
\n
\n

Higher Shaft Torque at Same Power<\/h3>\n

Motor shaft torque equals power divided by angular velocity. At 960 rpm, a 6-pole motor produces 50% more shaft torque than a 4-pole motor of the same rated power at 1440 rpm, and three times the torque of a 2-pole motor at 2880 rpm. For a 4 kW motor, this is the difference between 26.5 N\u00b7m (2-pole), 26.5 N\u00b7m (4-pole at 1440 rpm) and 39.8 N\u00b7m (6-pole at 960 rpm). This higher available torque means a smaller gearbox reduction ratio is needed for any given load torque requirement, directly reducing gearbox cost and weight.<\/p>\n<\/div>\n

\n

Reduced Kinetic Energy at Brake Engagement<\/h3>\n

The kinetic energy stored in a rotating motor rotor equals half the rotor inertia multiplied by the square of angular velocity. At 960 rpm, the rotor of a 6-pole motor stores 56% less kinetic energy than the same frame rotor spinning at 1440 rpm and 88% less than at 2880 rpm. This substantially reduces the thermal energy dissipated in the brake disc lining on each stop, extending lining service life by two to three times compared to the same number of stops on a 2-pole motor of equivalent power in the same frame.<\/p>\n<\/div>\n

\n

Gearbox Stage Elimination<\/h3>\n

A load requiring 20 rpm output with 200 N\u00b7m load torque would need a 4-pole motor running at 1440 rpm through a 72:1 gearbox, typically requiring a two-stage helical or two-stage worm arrangement. With a 6-pole brake motor at 960 rpm, a single-stage worm gearbox at 48:1 achieves the same output, removing one gear stage from the drivetrain. Single-stage elimination reduces drivetrain backlash, oil volume, maintenance frequency, and the number of shaft seals that can leak over time.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Frequently Asked Questions \u2014 Y2EJ Series 6-Pole Brake Motor<\/h2>\n
\n
\n
Why is the stopping time longer for the 6-pole than the 2-pole model at the same power?<\/div>\n
Stopping time depends on rotor kinetic energy and brake torque. The 6-pole rotor at 960 rpm stores less kinetic energy than a 2-pole rotor at 2880 rpm at the same power rating, so a smaller brake disc is needed. However, because the listed stopping time is measured from rated speed, the lower starting speed of the 6-pole motor means the deceleration time from 960 rpm to zero is naturally longer than from 2880 rpm to zero even with comparable braking deceleration rates. In practice, the stopping distance at the load shaft depends on the gearbox ratio as well as the motor stopping time.<\/div>\n<\/div>\n
\n
Can I use the 6-pole brake motor directly on a conveyor belt without a gearbox?<\/div>\n
Direct coupling at 960 rpm is possible for some conveyor belt speeds. A drive pulley of 305 mm diameter at 960 rpm gives a belt speed of approximately 15 m\/min, which is within the range of slow-speed material handling conveyors. For faster belt speeds, a gearbox is still needed, but the 6-pole motor allows a smaller ratio than a 4-pole motor at the same desired belt speed. For lower belt speeds (under 5 m\/min), a gearbox reduction is needed regardless of motor pole count, though the 6-pole motor minimises the required ratio.<\/div>\n<\/div>\n
\n
What is the maximum brake holding torque available in the 6-pole range?<\/div>\n
The largest model in the standard 6-pole range, Y2EJ180L-6 at 15 kW, provides a brake holding torque of 200 N\u00b7m at the motor shaft. Through a 10:1 gearbox, this becomes 2000 N\u00b7m at the load shaft \u2014 sufficient to hold a fully loaded conveyor, agitator shaft, or gate mechanism in the majority of industrial applications. For applications requiring brake torque above 200 N\u00b7m at the motor shaft, contact Korea Ever-Power for special brake disc configurations on the 180L frame.<\/div>\n<\/div>\n
\n
Is the 6-pole brake motor suitable for outdoor installation?<\/div>\n
The standard Y2EJ 6-pole is IP54, which provides protection against water splashing from any direction and is suitable for sheltered outdoor installations such as under canopies or in equipment enclosures. For fully exposed outdoor installation subject to driving rain or water jets, the IP55 variant should be specified. Both the motor frame and the brake housing carry the same IP rating as a combined assembly. Tropical-duty models with enhanced moisture-resistant winding impregnation are available on request for high-humidity environments.<\/div>\n<\/div>\n
\n
How does the 6-pole brake motor start under load at 960 rpm?<\/div>\n
At motor start, the control circuit simultaneously energises both the motor contactor and the brake rectifier. The brake electromagnet releases the friction disc before the motor builds up torque, allowing smooth acceleration from rest. The release time of the brake (typically 0.05 to 0.10 seconds) is shorter than the motor acceleration time (typically 0.5 to 2.0 seconds for a loaded 6-pole motor), ensuring the brake is fully released before significant motor torque is applied. This prevents brake disc dragging during acceleration, which would cause premature lining wear and motor overheating.<\/div>\n<\/div>\n
\n
What worm gearbox sizes pair with the 6-pole brake motor range?<\/div>\n
The NMRV and RV series worm gearboxes from Korea Ever-Power are matched to the Y2EJ 6-pole brake motor by IEC B5 flange coupling. Frame 71 and 80 brake motors suit NMRV040 and NMRV050 gearboxes; frame 90 and 100L suit NMRV063 and NMRV075; frame 112 and 132 suit NMRV090 and NMRV110; frame 160 and 180 suit NMRV130 and NMRV150. Standard ratios from 5:1 to 80:1 are available across the range, giving output speeds from 12 rpm to 192 rpm at 960 rpm input. See the Worm Gear Reducers<\/a> page for matched gearbox specifications.<\/div>\n<\/div>\n<\/div>\n
