Abstract
In some examples, a controller device includes processing circuitry configured to determine an alpha voltage and a beta voltage based on time durations for control signals for power-conversion circuitry that drives an electric motor including a rotor. In some examples, the controller device also includes a flux estimator configured to estimate a speed of the rotor and an angle of the rotor based on the alpha voltage and the beta voltage.
