Fail-safe operation. Millisecond-level braking response for hoisting, precision positioning, and emergency stops.
In vertical lifting, automated warehousing, and emergency stops, inertia is the problem. The YEJ Series integrates a DC electromagnetic brake.
When power is lost, spring force engages the brake and locks the rotor. Suspended loads stay in place, and automated equipment stops without position overshoot.

JWMotor offers you motor solutions with the following significant advantages
Fail-Safe Operation
The brake is a power-off design. If facility power fails, the brake locks the shaft so lifted loads do not free-fall and conveyors do not run away.
Rapid Response
With a rectifier module, the motor can go from power cut to a standstill in about 0.2 seconds. That suits indexing on automated assembly lines and stacker cranes.
Manual Release Handle
A manual release lever lets operators disengage the brake during a power outage, maintenance, or commissioning, so the shaft can be turned by hand.
Integrated Rectifier
The AC/DC rectifier sits in the terminal box. Connect a standard AC supply. No external DC cabinet is required.
Industry Applications
FAQ
What is the average braking time for YEJ series motors?
Braking is fast, typically 0.15 to 0.45 seconds depending on frame size. That suits elevators, packaging machinery, and other equipment that needs precise positioning or an emergency stop.
Can the YEJ motor be released manually during a power failure?
Yes. A manual release handle lets you release the brake and rotate the shaft during an outage or during maintenance.
How do I adjust the braking torque of a YEJ motor?
Braking torque is adjusted with the pressure springs in the brake assembly. For consistent friction, keep the air gap between 0.2 mm and 0.5 mm.
