Abstract
A method of operating a synchronous motor includes using a rotor angle observer model to calculate an observed rotor angle and a speed estimator model to calculate an observed angular speed of the rotor. The observed rotor angle may be used to ensure that the stator magnetic field generated by the stator is oriented 90° ahead of the rotor magnetic field. The observed angular speed may be used to regulate the motor operation to achieve the desired speed.
