Abstract
A split stator is manufactured in such a manner that an adhesive is applied on a teeth part of a split core to form an adhesive layer, the split core is inserted in a lower die, a molten insulator material containing fibrous fillers is injected in the die, and an upper die is moved to form an insulator. In the insulator, the fibrous fillers are oriented in random directions, providing increased thermal conductivity.
Claims10
A split stator member comprising:
- a split core member having a teeth part;
- and
- an insulator formed on an outer periphery of the teeth part with an adhesive layer being interposed therebetween,
- the insulator being formed of a resin material by resin molding directly around the adhesive layer on the outer periphery of the teeth part,
- the resin material is a resin containing a filler having a non-spherical shape, and
- the non-spherical filler is oriented in a random direction in the resin-molded insulator.
