PROBLEM TO BE SOLVED: To provide a drive for motor capable of attaining cost reduction in a circuit, and provide the drive for motor and a radiator cooling system which can reduce the number of harnesses connected to the motor. SOLUTION: The data from the sensor S1 of a motor 2 is read by a logic circuit 4 through harnesses A1 to A3. The timing of a switching circuit in a drive circuit 6 is controlled, so that the rotational speed of the motor 2 becomes a preset rotational speed from the data. In the drive circuit 6, the motor 2 and a motor 3 without sensors are connected, in parallel through harnesses B1 to B3 to deliver drive current to the motors 2, 3. |
