Abstract
An AC motor, and method of operation, including a synchronous motor with a magnetic rotor, and a stator positioned at a fixed distance from the magnetic rotor. A no-back mechanism is configured to oscillate when the synchronous motor is rotating in a desired direction, and the no-back component is configured to move to a stopping position when the synchronous motor is rotating in an undesired direction.
Claims20
An AC motor comprising:
- a synchronous motor;
- a magnetic rotor;
- a no-back component, wherein the no-back component is configured to oscillate when the synchronous motor is rotating in a desired direction, and wherein the no-back component is configured to move to a stopping position when the synchronous motor is rotating in an undesired direction;
- and
- a stator positioned at a fixed distance from the magnetic rotor.
2 more elements
An AC synchronous motor, comprising:
- a housing comprising a motor cup;
- a magnetic rotor within the motor cup;
- a stator within the motor cup and positioned at a fixed distance from the magnetic rotor;
- and
- a no-back component connected between the motor cup and the rotor, wherein the no-back component is configured to oscillate when the rotor is rotating in a desired direction, and wherein the no-back component is configured to rotate to a stopping position when the rotor is rotating in an undesired direction.
2 more elements
A method of operating an AC synchronous motor, the method comprising:
- rotating a rotor with respect to a stator within a motor cup in a first and desired direction;
- catching the rotor with a no-back component connected between the motor cup and the rotor when the rotor is rotating in a second and undesired direction.
