Abstract
The present invention relates to an operation control apparatus and a method for a commutatorless motor by which current flows in at least one of the windings of the motor during driving to maintain a large torque. The operation control apparatus and the method according to the present invention allow pulse signals to be output for driving the commutatorless motor in response to signals output from a revolution establishing unit and a rotor position detecting unit, whereby the pulse signals are output so that the delay time for controlling RPM can be obtained in order to allow the current to flow in one of the windings before the current flowing in another winding of the commutatorless motor is interrupted.
