Abstract
Generally described, the present disclosure is directed to examples of electric devices that include first and second stator assemblies located within a rotor assembly. The configuration of the electric device, including the configuration of the first and second stator assemblies, results in the electric device generating a stronger magnetic field and therefore outputting a higher torque when current is provided to the second stator assembly and generating a weaker magnetic field and therefore outputting a higher rotational speed when current is provided to the first stator assembly.
Claims25
An electric device comprising:
- an axle;
- a first stator assembly having a first pole and a first coil around the first pole;
- a second stator assembly having a second pole and a second coil around the second pole;
- and
- a rotor assembly having a housing and a plurality of permanent magnets coupled to the housing, wherein the first and second stator assemblies are located within the rotor assembly and are spaced apart from each other along a length of the axle.
An electrically powered vehicle comprising:
- an electric device that includes a rotor assembly, an axle, and first and second stator assemblies, the rotor assembly having a housing and a plurality of permanent magnets on the housing, each of the first and second stator assemblies having a pole and a coil wrapped around the pole, wherein the first and second stator assemblies are positioned within the rotor assembly and spaced apart from each other along a length of the axle.
A system comprising:
- an electric device that includes a rotor assembly, an axle, and first and second stator assemblies, the rotor assembly having a housing and a plurality of permanent magnets on the housing, each of the first and second stator assemblies having a pole and a coil wrapped around the pole, wherein the first and second stator assemblies are positioned within the rotor assembly at a spaced apart distance from each other along a length of the axle;
- a power source;
- and
- a controller coupled to the power source and the electric device, the controller configured to selectively electrically couple the power source to a respective one of the first and second stator assemblies.
A system comprising:
- an electric device that includes a rotor assembly, an axle, and first and second stator assemblies, the rotor assembly having a housing and a plurality of permanent magnets on the housing, each of the first and second stator assemblies having a pole and a coil around the pole, wherein the first and second stator assemblies are positioned within the rotor assembly at a spaced apart distance from each other along a length of the axle;
- a power source;
- a controller, the controller configured to generate control signals;
- and
- a switch coupled to the controller, the power source and the electric device, the switch configured to selectively couple the power source to a respective one of the first and second stator assemblies in response to receiving a control signal from the controller.
