Design concept of DC brake

Rapid braking: Utilizing a constant magnetic field generated by direct current, the rotor, due to inertia, cuts through this magnetic field, generating induced current and braking torque, significantly shortening downtime.

 

Eliminating "creeping" phenomenon: In variable frequency speed control systems, motors are prone to irregular creeping at low speeds. DC braking can intervene near zero speed, ensuring a smooth stop.

 

No mechanical wear: Compared to friction brakes, DC braking is electrical braking, requiring no contact parts, reducing maintenance needs, and extending service life.

 

Compatibility and integration: Can be built into a frequency converter, flexibly configured through parameters (starting frequency, voltage, time); can also be used as an independent module for power frequency motors.

 

Safety assurance: Suitable for elevators, cranes, fans, and other equipment with high requirements for stopping accuracy and safety, avoiding runaway or reverse start due to load inertia.
