摘要： An electric motor assembly including an electric motor and a flywheel assembly. The electric motor includes a rotatable shaft, at least a portion of the shaft being tapered as the shaft extends from the electric motor to an outer end of the shaft, the outer end of the shaft being threaded to receive a securing member. The flywheel assembly, which optionally includes a pulley and/or fan, includes a bore extending through a center of the flywheel assembly, at least a portion of the bore being tapered as the bore extends from an inner periphery facing the electric motor to the outer periphery of the flywheel assembly. The shaft of the electric motor extends through the bore of the flywheel assembly such that the taper of the shaft and the bore center the flywheel-pulley assembly on the shaft and create a self-holding taper arrangement. A securing member can be secured onto the outer end of the shaft to fix the flywheel assembly axially. Methods of forming and use are also provided.

摘要： A single coil, direct current permanent magnet brushless motor including a stator including six alternately-wound coils connected into a single coil having first and second ends, the oppositely-wound coils forming stator poles, and six magnets of alternating polarity coupled to a rotor and rotatably journaled in the stator. A sensor, such as a dual output Hall sensor, is used for sensing rotation of the rotor. A drive circuit, such as an H-bridge circuit, is coupled to the first and second ends of the single coil to drive the motor. The H-bridge circuit includes two high-side switches for alternately receiving signals from the Hall sensor, and two low-side switches alternately receiving signals from the Hall sensor. A high-side switching signal can be controlled by an inverted low-side switching signal. A voltage boost circuit is also provided, having capacitors to provide a boosted voltage to alternately turn on the high-side switches of the H-bridge. The capacitors can be charged by an unregulated bus voltage.
