Abstract
A circuit for calibration a motor position in a motor having multiple phases including first, second, and third phases is electrically connected to a first phase winding and a second phase winding of the motor. The circuit comprises a comparator having first and second inputs; and a plurality of resistors electrically connected between the motor and the comparator, the plurality of resistors comprising: first parallelly-connected resistors and second parallelly-connected resistors which are connected in series and are connected between the first input of the comparator and the first phase winding of the motor, third parallelly-connected resistors and two or more fourth parallelly-connected resistors which are connected in series and are connected between the second input of the comparator and the second phase winding of the motor, and fifth parallelly-connected resistors connected in series with the second parallelly-connected resistors and connected in series with the fourth parallelly-connected resistors.
