MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/158327
Kind Code:
A1
Abstract:
Provided is a motor in which the occurrence of looseness occurring between a bobbin and a stator can be reliably suppressed regardless of the gap in which variation occurs. Specifically, projection portions 7b2 provided at two places in a second bobbin 7b are fit in two positioning holes 8b4 among three positioning holes 8b4. The projection portions 7b2 are provided on the side end surface of the flange portion 7b3 of the second bobbin 7b constituting a second stator assembly 52. The side end surface of the flange portion 7b3 faces the end plate portion 8b1 of an external stator core 8b, and the projection portions 7b2 project toward the facing surface of the end plate portion 8b1, which faces the side end surface of the flange portion 7b3. The projection portions 7b2 are fit in the positioning holes 8b4, thereby receiving an external force from the end plate portion 8b1 in a direction A facing each other in a surface direction of the side end surface of the flange portion 7b3.
