Abstract
A resolver stator includes a stator coil which is fixed to magnetic poles of the resolver stator by a resin softer than an epoxy, whereby disconnection in the stator coil is avoided when the resolver stator is used in an environment in which temperature varies in a wide range. Wire ends of the stator coil are each wound around a terminal and fixed thereto such that one part of the wound wire end is left free from the terminal, whereby disconnection of wires is avoided.
Claims10
A resolver stator comprising:
- a stator coil including a plurality of winding portions each wound around a magnetic pole via ring-shaped insulation caps, the stator coil being impregnated with a liquid or melted resin and fixed to the magnetic poles by curing the resin, wherein:
- the resin is softer than an epoxy;
- and
- a peripheral part of one of the ring-shaped insulation caps is provided with a plurality of terminals, wire ends of the stator coil are each wound around one of the plurality of terminals such that each wire end and the terminal form a winding-connecting part, and the wire end and the terminal are fixed to each other by soldering or fusing at one portion of the winding-connecting part and are independent from each other at the remaining portion of the winding-connecting part such that the wire end disposed in the remaining portion of the winding-connecting part is formed as a free wire end.
