Abstract
A field gradient motor with a stator housing and first and second stator disks fixed to the stator housing for turning B-field flux lines 90 degrees toward a motor air gap of the field gradient motor. A shaft is rotatably retained by the housing, and a rotor has a hole and keyway for producing a nonferrous hole through the shaft. A plurality of tangentially magnetized triangular magnets are fixed to the rotor. In operation, the stator housing, the stator disks, the rotor, the permanent magnets, and the shaft cooperate with the coil produce an electromagnetic action of the motor. The stator housing can be an iron ring, and the first and second stator disks and the rotor can be steel.
Claims18
A field gradient motor comprising:
- a stator housing;
- a motor air gap in the field gradient motor;
- first and second stator disks fixed to the stator housing comprising means for turning B-field flux lines toward the motor air gap;
- a shaft rotatably retained by the housing;
- a rotor retained relative to the shaft;
- a plurality of permanent magnets fixed to the rotor;
- a coil;
- wherein the stator housing, the stator disks, the rotor, the permanent magnets, and the shaft cooperate with the coil produce an electromagnetic action of the motor.
