Patent ID: 8502487

Claim:
A motor energy recycling device, which is connected to a motor, a voltage regulating power capacitor for providing power required for the motor, and a switch unit for controlling the motor, the motor energy recycling device used to store energy released by the motor comprising: a switching device having a first end, a second end and a third end for being switched to connect the third end with the first end or with the second end; a first diode unit; a first capacitor connected to the motor and the first diode unit so as to use energy released by the motor to charge the first capacitor; a second capacitor connected to the third end; a first inductor connected to the first end and connected between the first capacitor and the first diode; a second diode unit; and a second inductor connected to the second diode and the second end so as to charge the voltage regulating power capacitor thereby accomplishing an energy recycling.
