Abstract
Method and apparatus for insulating induction machine conductive connectors by sliding a closed-end insulating sheath over the connector. The sheath is circumferentially secured to the conductive connector with a biasing element, such as an elastomeric stretchable fabric, stretch tape or heat shrink material. Additional insulative materials as well as resin curing catalysts or accelerants may be added to the sheath.
Claims13
An induction machine insulator, comprising:
- an electrically insulating, pliable sheath having closed lateral sides, a closed distal end, and an open proximal end, adapted for slidable insertion over and envelopment of an induction machine conductor inserted therein;
- a stretchable circumferential biasing element coupled to the sheath, and adapted for securing the sheath under tension over an induction machine conductor after insertion therein;
- and
- auxiliary insulation coupled to the sheath and arranged inside the sheath.
1 more element
An induction motor, comprising:
- a housing;
- a rotor rotatively coupled within the housing;
- a stator within the housing, concentrically enveloping the rotor, having a plurality of stator coils that are conductively coupled in series by stub connectors;
- and
- a plurality of induction machine insulators covering each stub connector, each insulator respectively having:
- an electrically insulating, pliable sheath having closed lateral sides, a closed distal end, and an open proximal end, slidably inserted over and enveloping the stub connector retained therein;
- a stretchable circumferential biasing element coupled to the sheath, and securing the sheath under tension over the stub connector;
- and
- auxiliary insulation coupled to the sheath and arranged inside the sheath.
