摘要： A control device converts a torque instruction value of an AC motor into a current instruction of AC motor, and employs current control in which feedback is performed by PI control to match an actual current value with the current instruction. Further, the control device sets a target flow rate of cooling water flowing through a coolant passage based on the converted current instruction, produces a signal for driving a water pump to circulate the cooling water at the target flow rate thus set and provides the signal to the water pump. A revolution speed of the water pump is restricted according to a signal of the control device such that the cooling water circulates through the coolant passage at the flow rate matching with the target flow rate.
