したステツプモータの制御装置。 It consists of a step motor and an encoder that generates a signal periodic to the rotation of the step motor. During constant speed rotation, the encoder signal is used (feedback) to switch the phase of the step motor and control the rotation. A step motor control device consists of a circuit (hereinafter referred to as an open loop control circuit) that controls the rotation by switching the phase of the step motor at a predetermined cycle when starting or stopping rotation (hereinafter referred to as an open loop control circuit). When the end of the closed loop is detected by the circuit that detects the end of the closed loop control, a separate motor rotation detection circuit detects the rotation speed of the motor, and determines the optimum speed for stopping the motor. A control device for a step motor, comprising a circuit that can select a phase switching procedure in accordance with the rotational speed.
