Abstract

The present invention relates to automobile seat motor including: a motor housing having a first flux ring coupling portion formed at the inside of the front side thereof; a first flux ring coupled to the first flux ring coupling portion and having a ring magnet coupled to the inside thereof; a motor shaft located at the center of the first flux ring coupling portion in such a manner as to be coupled rotatably to the motor housing; and a rotor located at the center of the inside of the ring magnet in such a manner as to be rotated together with the motor shaft.

Claims

1. An automobile seat motor comprising:

a motor housing having a first flux ring coupling portion formed at the inside of the front side thereof;

a first flux ring coupled to the first flux ring coupling portion and having a ring magnet coupled to the inside thereof;

a motor shaft located at the center of the first flux ring coupling portion in such a manner as to be coupled rotatably to the motor housing; and

a rotor located at the center of the inside of the ring magnet in such a manner as to be rotated together with the motor shaft.

2. The automobile seat motor according to claim 1, further comprising a commutator coupled to the front side of the rotor in such a manner as to be rotated together with the motor shaft.

3. The automobile seat motor according to claim 2, further comprising:

a brush holder into which the front side of the commutator is located; and

an end cap having a brush holder coupling portion to which the brush holder is coupled formed at the inside thereof and a motor shaft coupling portion to which the motor shaft is coupled rotatably.

4. An automobile seat motor comprising:

a motor housing having a second flux ring coupling portion formed at the inside of the front side thereof;

a second flux ring coupled to the second flux ring coupling portion and having a pair of segment magnets coupled to the inner surfaces of the top and bottom portions thereof;

a motor shaft located at the center of the second flux ring coupling portion in such a manner as to be coupled rotatably to the motor housing; and

a rotor located at the center of the inside of the pair of segment magnets in such a manner as to be rotated together with the motor shaft.

5. The automobile seat motor according to claim 4, further comprising a commutator coupled to the front side of the rotor in such a manner as to be rotated together with the motor shaft.

6. The automobile seat motor according to claim 5, further comprising:

a brush holder into which the front side of the commutator is located; and

an end cap having a brush holder coupling portion to which the brush holder is coupled formed at the inside thereof and a motor shaft coupling portion to which the motor shaft is coupled rotatably.
