Abstract
A stator structure includes at least one stator part having a single rolled steel sheet to serve as a waist post with a gap. A first stator part includes a first engaging portion. A second stator part includes a second engaging portion corresponding to the first engaging portion. The first and second stator parts are of the same material. When the first stator part is assembled with the second stator part, the first engaging portion is engaged with the second engaging portion so as to form the stator structure with a waist post.
Claims15
A stator structure, comprising:
- at least one stator part having a single rolled silicon steel sheet as a waist post with a gap, and a plurality of projections formed on two opposite ends thereof;
- and
- another two stator parts, each having an opening with a plurality of notches formed on an inner surface thereof;
- wherein a coil is directly wound and extends axially around the waist post, the projections pass through the notches and are securely fit with the notches, respectively.
A stator structure, comprising:
- a first stator part having a first connecting portion;
- a second stator part having a second connecting portion;
- a plurality of projections formed on two opposite ends of the first stator part and the second stator part;
- and
- another two stator parts, each having an opening with a plurality of notches formed on an inner surface thereof;
- wherein the first and second stator parts have the same shapes and are of the same material, the first connecting portion contacts the second connecting portion, and the first connecting portion is coupled with the second connecting portion to form a waist post of the stator structure for allowing a coil to be directly wound and to extend axially thereon, and the projections pass through the notches and are securely fit with the notches, respectively.
A stator structure, comprising:
- a first stator part having a single rolled silicon steel sheet with a waist post, and having a plurality of projections formed on two opposite ends thereof;
- and
- a second stator part having a silicon steel piece to be assembled with an end of the first stator part, and having an opening with a plurality of notches formed on an inner surface of the opening;
- wherein a coil is directly wound and extends axially around the waist post, the projections pass through the notches and are securely fit with the notches, respectively.
A stator structure, comprising:
- a first stator part having a single rolled silicon steel sheet;
- a second stator part having another single rolled silicon steel sheet;
- a plurality of projections formed on two opposite ends of the first stator part and the second stator part;
- and
- another two stator parts, each having an opening with a plurality of notches formed on an inner surface thereof;
- wherein the first and second stator parts are assembled with each other to form a waist post;
- a coil is directly wound and extends axially around the waist post, and the projections pass through the notches and are securely fit with the notches, respectively.
