Patent ID: 10916984

Abstract:
An axial flux rotor for use in a motor with a stator is provided. The rotor includes a body including an outer periphery defined by outside radius OR. The body further has a central opening defined by inner radius IR and a plurality N of rotor poles defining an axis of rotation of the body. The body has first and second opposed faces. The rotor also includes a plurality of spaced apart axially imbedded magnets extending from the first face. At least one of the axially imbedded magnets has a minimum depth defined by defined by the equation wherein BrS is the Remanent Flux Density of Surface Mounted Magnet, wherein OR is the outside radius of the body, wherein IR is the inner radius of the body, wherein N is the number of rotor poles, and wherein BrA is the Remanent Flux Density of Axially Imbedded Magnet.
