摘要： PROBLEM TO BE SOLVED: To provide a drive system to constitute a four-wheel drive vehicle using a motor, without using expensive parts such as an inverter. SOLUTION: This invention eliminates an inverter by directly supplying the ac power to a motor 2 without rectifying the output of a generator 1. In addition to that, this invention makes the output voltage of the generator 1 variable by adjusting the field current, and uses an induction motor 2 for a motor to obtain the same motion as by an inverter since the torque speed is variable following the input voltage.
