Abstract
An electric motor comprising a stator and a rotor, the stator comprising: a stator core having a yoke and a plurality of teeth extending inwardly from the yoke, a slot being formed between adjacent teeth; windings wound around the teeth; and a dielectric slot liner disposed between the stator core and the windings in each slot for insulating the stator core from the windings. Each slot liner comprises a body conforming the stator core in the slot and two ends each with a lip structure protruding relative to the body in a radial direction of the stator to increase the creepage distance between the winding and a distal end of a corresponding tooth of the stator core.
Claims7
An electric motor comprising:
- a stator and a rotor disposed in the stator, the stator comprising:
- a stator core having a yoke and a plurality of teeth extending inwardly from the yoke, a slot being formed between each pair of adjacent teeth;
- windings wound around the teeth;
- and
- a dielectric slot liner disposed between the stator core and the windings in each slot for insulating the stator core from the windings;
- wherein each slot liner comprises a body conforming to the stator core in the slot and two ends each with a lip structure protruding relative to the body in a radial direction of the stator to increase the creepage distance between the winding and a distal end of a corresponding tooth of the stator core.
