Abstract
The present invention relates to a stator core for improving the fixing properties of a magnet wire, and a motor in which the same is applied. Provided is a stator core which comprises a protrusion pattern part for fixing the distal end portion of a magnet wire, and thus eliminates a process of fixing the wire using a separate member during a wiring process, thereby improving processability and inhibiting an insulating film of the magnet wire from being damaged by an external force such as vibration.
Claims19
A motor, the motor comprising:
- a housing;
- a stator disposed in the housing;
- a rotor disposed in the stator;
- and
- a shaft disposed in the rotor,
- wherein the stator includes a stator core, an insulator coupled to the stator core, and a coil wound on the insulator,
- wherein the insulator includes a body part on which the coil is wound, an edge part extending from the body part, and a protrusion part protruding from the edge part,
- wherein the protrusion part is disposed closer to a top or bottom of the body part than to a center of the body part on an axial direction of the shaft, and
- wherein the protrusion part is disposed closer to one end of the edge part than to the body part.
