VEHICLE DRIVING AND BRAKING SYSTEM USING ELECTRIC MOTOR

摘要

PURPOSE: A vehicle driving and braking system using an electric motor is provided to generate the large amount of torque by using a planetary gear train to change the torque. CONSTITUTION: A vehicle driving and braking system using an electric motor includes an electric motor(20), a planetary gear train(50), a driving circuit(40), and a regenerative braking circuit(41). The electric motor(20) is installed at a wheel installation part of a vehicle. The planetary gear train(50) is coupled to a shaft of the electric motor and wheels of the vehicle. The driving circuit(40) is connected to the electric motor in order to drive the vehicle. The regenerative braking circuit(41) is connected to the electric motor(20) in order to perform a regenerating operation and a braking operation.
