Abstract
A method for operating a salient motor is provided. In one example implementation, the method can include determining, via a controller of the motor, a series of estimated injection angles. The method can further include injecting, via the controller, a high-frequency signal into the motor at each of the series of estimated injection angles to provide a series of high-frequency signal injections. The method can further include, responsive to each of the series of high-frequency signal injections, processing, via the controller, one or more signals associated with each of the series of high-frequency signal injections. The method can further include determining, via the controller, one or more operating parameters based at least in part on the series of estimated injection angles.
