摘要： Methods and apparatus are provided for an axial electric motor. The apparatus comprises, a stator having coils thereon for producing a magnetic field, a rotor rotated by the magnetic field, and an output shaft coupled to the rotor. The rotor includes a magnetic and non-magnetic component. The non-magnetic component has a lower density than the magnetic component. One or both of the rotor components have apertures therein for ventilation and weight reduction. Permanent magnets are desirably mounted on the magnetic component of the rotor facing the stator and portions of the rotor behind the permanent magnets are hollowed out to be thinner than portions of the rotor between the permanent magnets. This reduces rotor weight without significantly affecting magnetic flux density in the rotor or motor torque.

The coils are preferably formed from a flat ribbon a portion of whose principal surface is perpendicular to the teeth. A supporting frame is desirably fixedly coupled to the ring and rotatably coupled to the output shaft.

摘要： Methods and apparatus are provided for an electric vehicle embodying an axial flux traction motor directly coupled to a wheel thereof. The traction motor comprises a stator having coils for producing a magnetic field, an annular rotor magnetically coupled to the stator and mechanically to an output shaft. Permanent magnets of alternating polarity are mounted on the annular rotor. Magnetic shunts bridge a portion of the stator slots above the coils. The magnets are arranged in groups with group-to-group spacing exceeding magnet-to-magnet spacing. Adjacent edges of the magnets diverge. The method comprises, looking up d- and q-axis currents to provide the requested torque and motor speed for the available DC voltage, combining at least one of the d- and q-axis currents with a field weakening correction term, converting the result from synchronous to stationary frame and operating an inverter therewith to provide current to the coils of the motor.
