Title:
電動機システム
Document Type and Number:
Japanese Patent JP5350034
Kind Code:
B2
Abstract:
An electric motor system including: a rotor (9); a stator (8); the rotor and the stator being mounted for movement relative to one another; the rotor having multiple magnetic poles (11); the stator having multiple salient poles (12) facing the magnetic poles; a first coil set (1A) and a second coil set (1B); the first coil set having three phases, each of the phases comprising a first coil (u1, v1, w1) and a second coil (u1 v1′, w1′) connected in series and wrapped around different of the salient poles in different directions relative to the rotor; the second coil set having three phases, each of the phases comprising a first coil (u2, v2, w2) and a second coil (u2′, v2′, w2′) connected in series and wrapped around different of the salient poles in different directions relative to the rotor; a driver (2) configured to drive the first coil set with a first three-phase voltage (U1, V1, W1) and to drive the second coil set with a second three-phase voltage (U2, V2, W2); the driver configured to drive the first phase of the first three-phase voltage and the first phase of the second three-phase voltage with a relative phase shift.
