ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to electric motors and more specifically to a motor with an external rotor and a method for assembling the motor.
Motors with external rotors or “inside out motors” of the type to which the present invention generally relates have magnetic elements mounted on a rotor. These magnetic elements may include permanent magnets and/or electromagnets. A stator located inside the magnet elements includes a bearing for rotatably mounting a rotor shaft on the stator so that the rotor may rotate relative to the stator as a result of the magnetic interaction of the magnetic elements and magnetic fields generated by energizing windings of the stator. Typically, only one or two windings are wound on a bobbin of an inside out motor. Pole members provided around the bobbin, between the magnetic elements and the windings, direct the magnetic flux generated by the energized windings to improve the performance of the motor.
SUMMARY OF THE INVENTION
Generally, a method for assembling an inside out motor generally includes the steps of stacking a plurality of laminations together to form a pole member. A stator is molded around the pole member so that an end of the pole member is located adjacent an exterior surface of the molded stator. An electrically conductive magnet wire is wound around the molded stator adjacent the pole member to form a winding of the motor.
In another aspect of the invention, a method for molding a stator for use in an inside out motor includes stacking laminations together to form a pole member. The stator is molded around the pole member so that an end of the pole member is located adjacent an exterior surface of the molded stator. An electrically conductive magnet wire is wound around the molded stator adjacent the pole member.
Other objects and features of the invention will be in part apparent and in part pointed out hereinafter.
