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 a vibration preventing pattern formed protruding from an inner side of the coil-winding guide part.

2 . The guide member of claim 1 , wherein the coil-winding guide part partitions at least one guide groove on the upper surface of the guide member body with a partitioning wall.

3 . The guide member of claim 1 , wherein the coil-winding guide part partitions at least one guide groove on the upper surface of the guide member body with engraving.

4 . The guide member of claim 2 , wherein the vibration preventing pattern includes a plurality of patterns protruding from an inner wall of the guide groove toward the center thereof.

5 . The guide member of claim 4 , wherein the vibration preventing pattern includes at least one pair or more of a pair of patterns protruding in a center direction of the inner wall at positions facing each other at the inner wall of the guide groove.

6 . The guide member of claim 4 , wherein the vibration preventing pattern has a width which is one-third of an overall width (d) of the guide groove.

7 . The guide member of claim 4 , wherein the vibration preventing pattern includes at least one slope part having an angle of inclination from a virtual horizontal plane forming an upper surface of the guide groove.

8 . The guide member of claim 7 , wherein the angle of inclination of the slope part includes an acute angle.

9 . The guide member of claim 4 , wherein a vertex of a protruding part of the vibration preventing pattern has a rounded structure.

10 . The guide member of claim 4 , wherein the vibration preventing pattern is an elastic member.

11 . The guide member of claim 4 , wherein the vibration preventing pattern has one end in contact with the inner wall of the guide groove and the other end provided with a separate part separated from the inner wall of the guide groove.

12 . The guide member of claim 11 , wherein, in the vibration preventing pattern, the separate part separated from the inner wall of the guide groove has a width which becomes greater in a depth direction of the guide groove.

13 . The guide member of claim 4 , wherein the coil-winding guide part is mutually partitioned by a plurality of guide grooves, and at least one communicating part is formed between the guide grooves adjacent to each other.

14 . A stator of a motor, comprising:
a stator core including a plurality of teeth which protrude from an inner surface thereof toward the center thereof; a plurality of coils wound around the stator teeth; and a guide member configured to allow tip ends of the plurality of coils to be routed along a coil-winding guide groove formed on a surface thereof and including a vibration preventing pattern formed protruding from an inner wall of the coil-winding guide groove.

15 . 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 in the center of the stator; a guide member disposed on an upper side of the stator and configured to allow a part of the coil to be wound along a coil-winding guide groove formed on an upper surface thereof; and a plurality of vibration preventing patterns formed protruding from an inner wall of the coil-winding guide groove.
