Latest Patents
One of her latest patents is titled "Method and apparatus for monitoring rotational position of an electric machine." This invention involves a method for monitoring an electric motor using a pulse-type rotational position sensor. It includes monitoring a signal output from the sensor and a reference signal associated with the control signal for the electric motor. The position of the rotor is determined based on a nominal rotor position, nominal rotational speed, and the timing of the reference signal. The electric motor is then controlled based on the rotor's position.
Another significant patent is "Single processor dual motor control." This invention provides a motor control processor for sampling motor phase currents of multiple variable frequency controlled electric motors. It features an analog-to-digital (A/D) converter with multiple analog inputs and a controller that determines the maximum desired switching frequency for the motors. The controller selects a base period and defines a phase shift time delay to effectively control the sampling of motor phase currents.
