Patent

CA 2143866

A wound stator for a permanent magnet electric machine has an array of coils ("C") on the outer rim of a generally cylin- drical stator body (40). The stator coils ("C") are wound directly on the stator body (40) by providing the stator body with a plu- rality of mutually circumferentially-spaced, coil-retaining and forming members (52, 54) around which the ends ("E") of the sta- tor coils ("C") are coursed so that the coil sides ("S") project in a direction parallel to the center axis of the stator. Wire connections are formed between coils (60, 62, 64) of a phase, and wire loops (180) are formed between the last wound coil (60-10) of one phase and the first wound coil (62-1) of a subsequently wound phase. Mechanisms are provided for clamping the stator start wires and for temporarily retaining the wire loops (180).
