Electric brake and energy recovery system for brushless DC motor

Abstract

The energy recovery system applies reverse mode voltage on the motor coil when the electric brake system is activated, through synchronous switching controlling the up and down arm MOSFET, with the current flowing back to the source end when the arm closes, to achieve energy recovery. It relies on Gate voltage to switch signal, realizes the controllable reverse torque brake, provide smooth and reliable brake torque, without complex electric frame structure to recover the motor dynamic maximumly.
