The Standard Brake Motor for Hoists, Lifts, and Inclined Conveyors<\/h2>\n

The Y2EJ 4-pole brake motor is the most widely specified model in the Y2EJ range because 1400 rpm is the natural operating speed for the majority of hoist and conveyor applications. At this speed, gearbox ratios of 10:1 to 40:1 give load speeds in the 35 to 140 m\/min range that covers most pallet conveyor, car park lift, and material hoist specifications. The higher torque of the 4-pole winding versus the 2-pole at the same power rating also reduces the gearbox ratio required, allowing a smaller and lighter gearbox body in the total drive assembly.<\/p>\n

The integral spring-applied DC brake operates identically to the 2-pole variant but with a slightly longer stopping time (up to 0.2 seconds compared to 0.1 seconds for 2-pole) because the lower rotor speed means less kinetic energy is available to compress the spring through the friction pad. This modest difference has no practical consequence in hoist and conveyor applications where the load is statically held by the brake rather than decelerated to zero dynamically.<\/p>\n

Frame sizes run from 63M through 180L, covering 0.12 kW to 22 kW. All models share the same brake architecture: DC 205 V electromagnet coil, adjustable spring preload, replaceable friction disc, and optional manual brake release lever. The brake housing is enclosed within the extended non-drive-end shield and rated IP54 as part of the overall motor assembly.<\/p>\n

Typical Applications for Y2EJ 4-Pole Brake Motors<\/h2>\n\n\n\n
\"Y2EJ<\/p>\n
\n
Inclined Belt Conveyors<\/div>\n
Inclined conveyors carrying bulk material or unit loads use the 4-pole brake motor to prevent loaded belt rollback on power interruption. The spring-applied brake holds the full loaded belt weight without hydraulic or pneumatic backup systems, simplifying the installation and reducing maintenance requirements.<\/div>\n<\/div>\n<\/td>\n
\"Y2EJ<\/p>\n
\n
Material Hoists<\/div>\n
Wire rope hoists and chain hoists in warehouses and workshops use the 4-pole brake motor because it delivers the combination of moderate lifting speed, high torque, and immediate load holding that suspended load safety regulations require in the majority of jurisdictions.<\/div>\n<\/div>\n<\/td>\n
\"Y2EJ<\/p>\n

Food Line Positioning<\/div>\n
Vertical lifts and transfer gates on food production lines use brake motors to hold product-carrying platforms and gates in position during filling or inspection operations, eliminating the need for separate mechanical locking devices that would require cleaning and certification.<\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n

Why the 4-Pole Variant Is the Most Specified Brake Motor in the Y2EJ Range<\/h2>\n
\n
\n

Torque-Speed Match for Hoist Gearboxes<\/h3>\n

Most hoist gearboxes are designed for input speeds of 1000 to 1500 rpm. The 4-pole motor at 1400 rpm sits in the centre of this range, giving the gearbox designer maximum flexibility in ratio selection. A 2-pole motor at 2800 rpm requires a higher gearbox ratio for the same output speed, increasing gearbox size and cost. A 6-pole motor at 960 rpm provides higher input torque but limits the maximum ratio range available in standard catalogue gearboxes. The 4-pole motor is therefore the natural choice for the largest selection of catalogue hoist and gearmotor combinations.<\/p>\n<\/div>\n

\n

Brake Torque and Load Inertia<\/h3>\n

The brake torque listed in the specification table is the motor shaft torque applied by the brake disc. Reflected through the gearbox, this becomes a much larger braking torque at the load shaft: a 55 N\u00b7m brake torque at the motor shaft becomes 550 N\u00b7m at the load shaft through a 10:1 gearbox. This gearbox multiplication means that relatively small brake motor units can hold very large loads, which is why the Y2EJ range covers hoist applications well above the motor power rating alone would suggest.<\/p>\n<\/div>\n

\n

Duty Cycle and Heat Management<\/h3>\n

Hoist and conveyor applications involve frequent start-stop cycles (S3 duty). Each braking event dissipates kinetic energy as heat in the friction disc lining. The 4-pole motor at 1400 rpm stores less kinetic energy per unit of rotor inertia than the 2-pole motor at 2800 rpm, so the thermal load on the brake disc per stopping event is lower. This translates directly to longer lining life in high-cycle applications and a lower frequency of brake disc replacement in intensive production hoist and conveyor duties.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Frequently Asked Questions \u2014 Y2EJ Series 4-Pole Brake Motor<\/h2>\n
\n
\n
Is the brake certified for suspended load (hoist) applications?<\/div>\n
The Y2EJ brake motor meets the requirements of IEC 60034 and the brake assembly is designed to IEC 60947-4 for holding duty in hoist applications. For applications subject to specific national hoist safety regulations or crane standards (such as FEM, ISO 4301, or EN 14492), the user must verify that the brake torque and duty cycle rating of the specific Y2EJ model meets the requirements of those standards for the intended hoist capacity and duty classification. Korea Ever-Power can provide technical documentation to support compliance assessments.<\/div>\n<\/div>\n
\n
How is brake torque specified relative to motor torque?<\/div>\n
Brake holding torque is typically set to 1.5 to 2.0 times the rated motor torque at full load. For a Y2EJ90L-4 at 1.5 kW and 1400 rpm, rated motor torque is approximately 10.2 N\u00b7m. The brake holding torque of 13.0 N\u00b7m is 1.27 times rated motor torque, providing a margin against dynamic braking loads from load inertia during deceleration. For applications with high load inertia, contact Korea Ever-Power to verify that the brake torque is sufficient to decelerate the load within the required stopping distance.<\/div>\n<\/div>\n
\n
What happens if the brake coil fails while the motor is running?<\/div>\n
If the brake coil or rectifier fails, the DC current collapses and the spring-applied brake engages automatically, stopping and holding the load. This is the fail-safe design principle: the brake is safe in the power-off state by default. The motor will stop and be held by the brake springs until the coil fault is rectified. A brake coil failure is therefore a safe condition from a load-holding perspective, though it prevents further motor operation until the coil or rectifier is replaced. Coil and rectifier replacement kits are available from Korea Ever-Power service centres.<\/div>\n<\/div>\n
\n
Can the brake be wired to engage before the motor fully stops?<\/div>\n
In the standard wiring configuration, the brake is released and applied simultaneously with the motor contactor. For faster positioning stops, the motor contactor can be opened slightly before or simultaneously with brake application, allowing the brake to decelerate the rotor from running speed rather than merely holding a stationary load. This increases brake disc wear per cycle but reduces positioning time. Separate brake and motor contactors with independent timing control, managed by a PLC output, are the standard implementation for this operating mode.<\/div>\n<\/div>\n
\n
Is the brake protected to the same IP rating as the motor?<\/div>\n
Yes. The brake is enclosed within the extended non-drive-end shield of the motor and the complete assembly (motor, brake, and rectifier box) is rated IP54 as a unit. The brake housing, air-gap adjustment ring, and inspection window are all sealed to this rating. For washdown environments or outdoor applications requiring IP55, the complete Y2EJ motor and brake assembly is available in IP55 rating on request from Korea Ever-Power.<\/div>\n<\/div>\n
\n
What is the maximum number of starts per hour for the brake motor?<\/div>\n
The maximum permissible number of starts per hour (S3 duty cycle) depends on motor frame size and the ratio of starting energy to rated power. For standard Y2EJ 4-pole models from frame 63 through 132, the maximum is typically 60 starts per hour at rated load. For frame 160 and above, the limit reduces to 30 starts per hour at rated load due to the larger rotor thermal mass requiring more cooling time between starts. Higher cycling rates are possible at reduced load fractions; consult the motor technical datasheet for the specific model and duty point.<\/div>\n<\/div>\n<\/div>\n
