FIELD: electricity.SUBSTANCE: low-noise energy-saving electric drive includes rotary electric machine with number of poles of 2p, equal to 4 or more, and control device. An asynchronous motor with combined winding is used as the machine. The control device comprises p controllers; at that one of them may be the master controller, while other ones may be slave controllers. Moreover each pair of poles is supplied with power from a separate controller.EFFECT: improved energy-saving and reliability of the drive, reduced acoustic noise level.1 dwg |
