Abstract
A motor includes a sheet-like gasket for sealing the gap between a stator core and an encoder. The gasket has a structure including a metal plate and a sealing member covering the metal plate, and the gasket includes a first portion that is disposed at least between the end face on one end side of the stator core and the encoder and a second portion that has a structure including the sealing member with no metal plate and extends inward from the first portion to contact the projection.
Claims5
A motor, comprising:
- a stator core configured to have a through hole in which a rotor is arranged;
- an encoder provided on a first end side of the stator core and configured to have a projection protruding into the through hole;
- and
- a sheet-like gasket configured to have a communication hole communicating with the through hole and seal a gap between the stator core and the encoder,
- wherein the gasket has a structure including a metal plate and a sealing member that covers the metal plate, and
- the gasket includes
- a first portion that is disposed at least between an end face on the first end side of the stator core and the encoder and
- a second portion that has a structure including the sealing member with no metal plate and extends inward from the first portion to contact the projection.
