Integrated Drive System and Electric Vehicle

An integrated drive system that includes a motor having a housing and an output shaft is disclosed. The integrated drive system further includes a planetary gear transmission mechanism having a first-stage planetary gear mechanism and a second-stage planetary gear mechanism. The first output torque of the first-stage planetary gear mechanism is transmitted to a driven object. The second output torque of the first-stage planetary gear mechanism is transmitted to the second-stage planetary gear mechanism. And the third output torque of the second-stage planetary gear mechanism is transmitted to the driven object. An electric vehicle that includes the described integrated drive system is also disclosed.
