PURPOSE:To equalize the load share of a plurality of motors by operating the motors by a torque control system which inputs the same torque command signal as an input signal, and mechanically coupling the motors by a reduction gear. CONSTITUTION:The first control system of a main control system is composed of a detector 13, an error amplifier 14, a converter 15-1, a drive circuit 16-1, a brushless motor 10-1 and a resolver 11-1, the second control system of a sub control system is composed of a converter 51-2, a drive circuit 16-2, a brushless motor 10-2, and a resolver 11-2, and the third control system of the sub control system is composed of a converter 15-3, a drive circuit 16-3, a brushless motor 10-3, and a resolver 11-3. The motors 10-1-10-3 are mechani cally coupled by a reduction gear 20 so as not to cause mechanical angle dis placement. |
