Abstract
Embodiments of the present disclosure include insulating devices, motor stators, and motors. The insulating device comprises at least one insulating frame and at least one insulating wrapping layer; the insulating frame has at least two support ends with the same orientation and arranged at intervals; the insulating wrapping layer is a cylindrical structure, and at least one open end of the cylindrical structure wraps the at least two support ends on the insulating frame and is supported by the support ends to form a winding space. The insulating device can balance the copper wire space factor and the manufacturing cost.
Claims10
An insulating device comprising:
- an insulating frame with two support ends sharing an orientation and arranged at intervals;
- and
- an insulating wrapping layer having an elongated hollow rectangular structure, the elongation defining a primary axis;
- wherein an open end of the elongated hollow rectangular structure wraps the two support ends on the insulating frame and is in turn supported by the two support ends to form a winding space in an interior of the elongated hollow rectangular structure;
- wherein a stator winding extends through the winding space along a primary axis.
A motor stator comprising:
- a stator core with windings;
- and
- an insulating device including an insulating frame with two support ends sharing an orientation and arranged at intervals, and an insulating wrapping layer having an elongated hollow rectangular structure, the elongation defining a primary axis;
- wherein an open end of the elongated hollow rectangular cylindrical structure wraps the two support ends on the insulating frame and is in turn supported by the two support ends to form a winding space in an interior of the elongated hollow rectangular structure;
- wherein the stator core has a stator slot;
- wherein a stator winding extends through the winding space along a primary axis
- the insulating wrapping layer is positioned in a stator slot and runs through the stator slot;
- and
- the insulating frame supports a corresponding insulating wrapping layer from one end of the stator slot.
