ABSTRACT:
A high speed DC brushless motor in which the stator is toroidal and the stator core does not include winding slots. In the preferred embodiment the core material for the stator is an amorphous metal alloy which provides high speed motor efficiency. For some applications core materials like ferrite or low silicon-alloys can be used. According to one embodiment of the invention a ferrite shielding ring can be added surrounding the motor to further improve high speed efficiency.
