Title:
MOTOR AND ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/100580
Kind Code:
A1
Abstract:
A motor according to one embodiment is provided with an n-phase coil group (where n is an integer of 3 or higher), a first inverter connected to one end of the n-phase coil group, a second inverter connected to the other end of the n-phase coil group, a stator on which the n-phase coil group is wound, and a rotor capable of rotating relative to the stator. At least one coil group of the n-phase coil group includes a first sub-coil group including a first coil and a second coil that are connected to each other in series, and a second sub-coil group including a third coil and a fourth coil that are connected to each other in series. The first sub-coil group and the second sub-coil group are connected to each other in parallel.
