Abstract
An insulating jacket structure of a stator of a direct current motor includes a body, and multiple extension plates extended outward from the body. Each of the extension plates has an inverted U-shaped receiving recess which has two sides having two distal ends each formed with a protruding locking snap. Multiple outer annular plates are extended outward from the two sides of the receiving recess, and a gap is formed between any two adjacent outer annular plates. The poles of the silicon steel plate assembly of the stator are received in the receiving recess, and the silicon steel plate located at the lowermost layer of the silicon steel plate assembly is snapped and locked by the locking snaps of the receiving recess.
Claims7
An insulating jacket structure of a stator of a direct current motor, comprising:
- a body, having a through hole;
- and
- multiple extension plates, extended outward from the through hole of the body in a radiating manner, each of the multiple extension plates having a receiving recess whose cross-section is substantially inverted U-shaped, the receiving recess of each of the multiple extension plates having two sides having two distal ends each formed with a protruding locking snap.
An insulating jacket structure of a stator of a direct current motor, comprising:
- an insulating jacket body, having a through hole;
- multiple extension plates, extended outward from the through hole of the insulating jacket body in a radiating manner, each of the multiple extension plates having a receiving recess whose cross-section is substantially inverted U-shaped, the receiving recess of each of the multiple extension plates having two sides having two distal ends each formed with a protruding locking snap;
- multiple outer annular plates extended outward from the two sides of the receiving recess at the distal ends of each of the multiple extension plates, and a gap being formed between any two adjacent outer annular plates;
- and
- a silicon steel plate assembly, laminated by multiple silicon steel plates, and having a hub, multiple poles and multiple pole faces, each of the poles of the silicon steel plate assembly received in the receiving recess of each of the multiple extension plates of the insulating jacket, wherein the silicon steel plate located at the lowermost layer of the silicon steel plate assembly is snapped and locked by the locking snaps protruded from the two distal ends of the receiving recess, the hub of the silicon steel plate assembly is located in the through hole of the insulating jacket body, and each of the pole faces is located outside of each of the multiple outer annular plates.
