Abstract
An electric device includes a motor and a motor drive for commanding a torque generated by the motor. A fault control circuit detects a fault condition associated with the motor drive. Upon detection of the fault condition, the fault control circuit adjusts the torque commanded by the motor drive.
Claims15
An electric device comprising:
- a motor having a first winding set and a second winding set;
- and
- a fault control circuit for decoupling one of the first winding set and the second winding set from all circuitry based at least on a fault condition.
The electric device according to claim 17, wherein the component is one of the first winding set, a power source, a motor drive, a sensor, a CPU, and a RAM.
A method for controlling an electric device, the electric device including a motor, the motor having a winding set, the method comprising:
- detecting a fault condition associated with the winding set;
- and
- decoupling the winding set from all circuitry based at least on the fault condition.
