Abstract
A motor control circuit for controlling an electric motor may include at least one switching device configured to receive, from a pulse modulation device, a pulse modulated signal and output, based on the pulse modulated signal and to the electric motor, a current. In some examples, a frequency of the pulse modulated signal is below a threshold frequency. The motor control circuit may also include a transient detection circuit configured to detect a current transient, and responsive to detecting the current transient, output a pulse. The motor control circuit may further include a pulse counter configured to update, based on the pulse, a value indicative of a position of a rotor of the electric motor; and output the value indicative of the position of the rotor.
