Abstract
There is provided a motor device. A motor device according to an aspect of the invention may include: a stator including a core having a coil wound therearound; a rotor having a magnet facing the core to thereby generate an electromagnetic force involved in interactions therebetween, the rotor rotating a shaft; a sleeve supporting the shaft; and a sleeve housing having a mounting surface to support the core and a protrusion protruding from the mounting surface to prevent a rotation of the core.
Claims3
A motor device comprising:
- a stator including a core having a coil wound thereround;
- a rotor having a magnet facing the core to thereby generate an electromagnetic force involved in interactions therebetween, the rotor rotating a shaft;
- a sleeve supporting the shaft;
- and
- a sleeve housing having a mounting surface to support the core and a protrusion protruding from the mounting surface to prevent a rotation of the core, the protrusion being formed monolithically with the sleeve housing, wherein
- the sleeve housing is formed monolithically with a base plate supporting the stator;
- and
- the protrusion, the sleeve housing, and the base plate are formed by pressing a single plate having a plate-like shape downwardly.
