Abstract

The present invention relates to a structure of a guide member performing a vibration preventing function of a coil and a motor using the same. In the structure of the guide member which guides the coil wound around a stator to an external power module, and a vibration preventing pattern is provided in a coil guide groove, thereby implementing a stable fixing force of the coil when the motor is driven and solving a problem of noise due to a vibration of the coil. Therefore, a steering wheel is operated more stably.

First claim

What is claimed is:

1. A guide member for a motor, the guide member comprising:
a guide member body;
at least one coil-winding guide part provided on an upper surface of the guide member body; and

wherein the coil-winding guide part is partitioned by at least one partitioning wall to form a plurality of guide grooves on the upper surface of the guide member body,
wherein the vibration preventing pattern includes an upper slope part and a lower slope part each forming an acute angle of inclination with respect to a virtual horizontal plane extending from an upper surface of the coil-winding guide part, the lower slope part extending in a direction different from that of the upper slope part, and
wherein a vertex of a protruding part of the vibration preventing pattern has a rounded surface in contact with a coil.

2. The guide member of claim 1 , wherein the vibration preventing pattern includes at least one pair of patterns protruding away from an inner wall of the coil-winding guide part to face each other.

3. A motor comprising:
a motor housing;
a stator installed inside the motor housing and including a stator core and a coil wound around the stator core;
a rotor rotatably installed at a center of the stator;
a guide member according to claim 2 , the guide member being disposed on an upper side of the stator and configured to allow a part of the coil to be wound along the guide grooves of the guide member.

4. A stator of a motor, comprising:
a stator core including a plurality of stator teeth protruding from an inner surface of the stator toward a center of the stator;
a plurality of coils wound around the stator teeth; and
a guide member according to claim 2 , the guide member being configured to allow tip ends of the plurality of coils to be routed along the guide grooves of the guide member.

5. The guide member of claim 1 , wherein the vibration preventing pattern has a width that is one-third of an overall width (d) of one guide groove of the guide grooves.

6. A motor comprising:
a motor housing;
a stator installed inside the motor housing and including a stator core and a coil wound around the stator core;
a rotor rotatably installed at a center of the stator;

a stator core including a plurality of stator teeth protruding from an inner surface of the stator toward a center of the stator;
a plurality of coils wound around the stator teeth; and
a guide member according to claim 8 , the guide member being configured to allow tip ends of the plurality of coils to be routed along the guide grooves of the guide member.

11. The guide member of claim 1 , wherein at least one communicating part ( 211 ) is formed between the guide grooves adjacent to each other.

12. A motor comprising:
a motor housing;
a stator installed inside the motor housing and including a stator core and a coil wound around the stator core;
a rotor rotatably installed at a center of the stator;
a guide member according to claim 11 , the guide member being disposed on an upper side of the stator and configured to allow a part of the coil to be wound along the guide grooves of the guide member.

13. A stator of a motor, comprising:
