ABSTRACT:
An apparatus for controlling a rotational motion of a motor is disclosed which includes: a signal generator generating a rotational state signal indicative of a rotational state of the motor; and a controller producing a control signal for controlling the rotational motion of the motor, based on the rotational state signal generated by the signal generator, to thereby control the motor based on the produced control signal. The controller produces the control signal during a start up of the motor, such that the produced control signal is not affected by a noise component which is incorporated into the rotational state signal during the start up of the motor.
