Abstract

PURPOSE:To increase the reliability of a stop control and to eliminate a backup mechanism, by shifting a rotor to the constant position stop range after once decelerating the rotor down to the zero speed. CONSTITUTION:A position detecting means 4 detects a magnet 3 mounted to a part of a rotor 2 which is driven by a motor 1; and a comparing part 5 which produces the signal to give a forward or backward drive to the motor 1 at both sides of a blind sector of a certain range and to the output signal. Furthermore a speed control means 12 gives a control to the motor 1 to a slow speed, forward low speed and backward low speed each; and a means 6 detects that the speed of the motor is reduced to zero. Thus a slow operation is given to the motor 1 by a stop command after the speed of the motor is reduced to a level near zero. Then a speed control is given to the motor 1 under a forward or backward low speed when a specific point of the rotor 2 reaches a prescribed control range that is decided by the output of the detector 4. And the motor 1 is stopped when the specific point of the rotor 2 reaches the blind sector.
