Title:
MOTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/116732
Kind Code:
A1
Abstract:
An insulator 42 is provided with a first region AR1 corresponding to the base end side of a tooth 41b and a second region AR2 corresponding to the top end side of the tooth 41b. A step portion 42e that hollows the first region AR1 with respect to the second region AR2 is also provided between the first region AR1 and the second region AR2. This allows a coil 26 corresponding to a coil layer CL1 to be hooked to the step portion 42e, suppressing the shift of the coil 26 along the projection direction of the tooth 41b. Accordingly, it is possible to align coil layers CL1, CL2, CL3 in order in the projection direction of the tooth 41b and improve the space factor of the coil 26 while suppressing variation in the number of turns of and the length of the coil 26 comprising the coil layers CL1, CL2, CL3.
