发明名称 LOAD DEVICE DRIVE SYSTEM
摘要 PROBLEM TO BE SOLVED: To provide a load device drive system which can suppress radiation of electromagnetic waves. SOLUTION: An electric converter housing 1 and a motor housing 2 are fixed on a conductor board 3 with screws 5 at respective bottom surfaces. The impedance of a feedback route from the motor housing 2 to the electric converter housing 1 through the conductor board 3 is small, therefore, a phase difference between noise current running through a wire 4 and noise current running through the electric converter housing 1 from the motor housing 2 via the conductor board 3 becomes small, so that the amount of electromagnetic waves radiated toward a space becomes small.
