Abstract
A wound stator for a permanent magnet electric machine has an array of coils on the outer rim of a generally cylindrical stator body. The stator coils are wound directly on the stator body by providing the stator body with a plurality of mutually circumferentially-spaced, coil-retaining and forming members around which the ends of the stator coils are coursed so that the coil sides project in a direction parallel to the center axis of the stator. Wire connections are formed between coils of a phase, and wire loops are formed between the last wound coil of one phase and the first wound coil of a subsequently wound phase. Mechanisms are provided for clamping the stator start wires and for temporarily retaining the wire loops.
