Abstract

A method for winding a stator of a multi-phase motor includes successively winding each of a plurality of teeth on the stator with a continuous winding wire to connect each of the phases in the motor together. The wound wire is disconnected between any two phases where respective ends of the two phases connected by the winding wire are not neutral ends. A jumper wire is connected between a neutral end of any one of the phases to a neutral end of at least one other phase if the neutral end of any one of the phases is not connected to the neutral end of at least one other phase by the winding wire.

Claims (9)

1. A method for winding a stator of a multi-phase motor, said method comprising the steps of:

successively winding each of a plurality of teeth on the stator with a continuous first wire to connect each of the phases in the motor together;

disconnecting said first wire between any two phases where respective ends of the two phases connected by said first wire are not neutral ends; and

connecting a second wire between a neutral end of any one of the phases to a neutral end of at least one other phase if said neutral end of said any one of said phases is not connected to said neutral end of said at least one other phase by said first wire,

wherein said first wire connects any two phases where respective ends of said any two phases are neutral ends.

2. The method as defined in claim 1 , further comprising the step of routing said first wire through a plurality of slits in an insulator attached to an end of said stator when winding from one tooth to the next tooth.

3. The method as defined in claim 2 , wherein said slits have differing depth to prevent said first wire from making electrical contact between any of the phases.

4. The method as defined in claim 1 , wherein said stator is wound using a needle winder.

5. The method as defined in claim 1 , wherein said stator is wound in a single tooth winding pattern.
