PROBLEM TO BE SOLVED: To reduce radio interference and reduce manufacturing costs by integrally installing an inverter unit into a motor. SOLUTION: A motor main body 11 and an inverter unit 12 are disposed in a case body 13 to unify them as one motor 10. The input terminal of the inverter unit 12 is connected to an external AC power source 17 and its output terminal is connected to the terminal of the motor body 11 in the state of nearly direct connection, and also control equipment 16 is electrically connected thereto. The inverter unit 12 is controlled by a predetermined control signal supplied from the control equipment 16, and the shaft 14 of the motor body 11 is rotated and controlled at a predetermined speed. Also, the inverter unit 12 is cooled by a fan 15 disposed in the shaft 14. |
