Electric rotating machine and stator for the same
An electric rotating machine has a rotor having N and S poles and includes a stator with an annular stator core and slots. Multiple-phase stator windings are embedded in the slots, and are formed by winding continuous wires such that straight parts of the stator windings pressed in a flat shape are wound in rings around a grooved cylindrical member. The cylindrical member is inserted into a bore defined by the annular stator core so that the grooves of the cylindrical member are arranged opposite to the slots. The sets of the windings are folded back alternately outside the slots of the stator core and are wound so the sets of the windings are embedded alternately in the direction of the depth of the slots. Leading and trailing ends of the continuous wires are superposed after being wound at least one turn around the circumferentially arranged slots of the stator.
