WebDynamic Braking (DB) The DC bus voltage level of an AC drive increases while the motor is re-generating (i.e. ramping to a stop). Dynamic braking resistors provide a means of rapidly stopping a rotating motor and load while maintaining an acceptable bus voltage level. The kinetic energy stored in the spinning mass is converted into electrical ... WebIn dynamic braking of small ac motors by the use of capacitors, the braking is independent of the power supply; furthermore, the capacitor furnishes a power-factor correction while the motor is operating.
