  • FAQ: What is dynamic braking and when is it used?

    Aug 15, 2016· Dynamic braking or regeneration? Dynamic braking is used when energy needs to be dissipated periodically, and regeneration is generally preferred when the motor is frequently acting as a generator.

  • Regenerative brake Wikipedia

    Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. This contrasts with conventional braking
