PURPOSE:To provide a motor driver which can perform a positive control operation by. eliminating the need for the operation of a relay. CONSTITUTION:After the rotation direction of a motor shaft 20 is inverted since the output from a control means 2 is switched from a first rotation direction command signal to a second rotation direction command signal, the operation of a first movable contact RL1-1 is prohibited for a predetermined amount of time by a prohibition means 5. Then, after the rotation direction of the motor shaft 20 is inverted since the output from the control means 2 is switched from the second rotation direction command signal to the first rotation direction command signal, the operation of a second movable contact RL2-1 is prohibited for a predetermined amount of time by the prohibition means 5. |
