Abstract
A control system for an electric motor is arranged to determine the position of the motor from at least one electrical parameter by means of a position determining algorithm which is reliant on movement of the motor to determine the motor position, and to start up the motor from rest by applying voltages to the motor that are independent of the position of the motor.
