ABSTRACT:
In a brushless dc motor, commutation is performed without the use of rotor position sensors. A voltage across a non-conducting winding of the motor is measured, a voltage across a conducting winding of the motor is computed, an emf Park vector is computed from the voltages, an imaginary component of a rotated emf Park vector is extracted, and the imaginary component is processed to determine when to perform the commutation from one winding to the next sequential winding.
