Abstract

A method of forming a stator for a brushless motor comprising providing a stator core having a generally rectangular body and having a plurality of teeth extending generally perpendicularly from a side of the body, and forming the stator core into a generally circular shape.

Claims

1. A method of forming a stator for a brushless motor comprising:

providing a stator core having a generally rectangular body and having a plurality of teeth extending generally perpendicularly from a side of the body, each of the teeth including a tip portion having extending flanges; and

bending the body of the stator core in the direction of the extending teeth until the extending flanges of the tip portions contact the extending flanges of adjacent teeth, thereby forming the stator core into a generally circular shape.

2. The method according to claim 1 further including placing a coil of electrical wire around each of the teeth prior to forming the stator core into a generally circular shape.

3. The method according to claim 2 wherein placing a coil of electrical wire around each of the teeth includes wrapping the electrical wire around each tooth.

4. The method according to claim 2 wherein placing a coil of electrical wire around each of the teeth includes forming a plurality of coils of electrical wire and placing one of the plurality of coils on each of the teeth.
