dynamic braking

Definitions

Electronics

  • A technique for quickly stopping an electric motor. To brake, the motor is disconnected from its power source, thereby becoming a generator. Then, a connected resistor dissipates the energy of rotation into heat. Also called resistance braking.
  • dynamic braking (1) in which the generated energy is stored, instead of being dissipated into heat. Used, for instance, in specially-equipped trains or cars. Also called regenerative braking.
