Abstract
In various embodiments, a method of controlling a motor and motor control system may be provided. The method may include applying exciting pulse-width-modification (PWM) or continuous sinusoidal voltages to a motor. The method may further include measuring one or more the applied exciting voltages to the motor. The method may further include measuring one or more currents from the motor. The method may also include calculating one or more back electromotive force (BEMF) voltages based on the one or more currents. The method may include adjusting the exciting voltages based on the one or more back electromotive force (BEMF) voltages and the phase angle difference between the calculated back EMF voltages and the measured currents. The motor control system may include the various detecting circuits of the exciting voltages and the motor currents from the motor with low pass filters.
