    In an machine this type(Refer Photo) of motor used for shifting purpose.Old one was damaged so I'm trying to change the new motor.

    It having only two wires.When these wires are interchanged,the motor running in both clockwise and anti clockwise direction.
    But some times,if the motor is wired for clockwise direction means also the motor running in anticlock wise direction.
    Working Voltage:230VAC
    Please help to solve the issue..

    Synchronous motors such as this will run either direction.
    If a particular direction is required, you will have to acquire one which has an internal spring or mechanism, which, if motor starts in the wrong direction, the spring/mechanism loads up and throws the rotor in the opposite/correct direction.

    The motor is labelled CCW/CW in other words, counter clockwise/clockwise.

    A two wire AC connection cannot determine the direction. The motor sees no difference when the two wires are reversed. So there is not "wiring it for CW" or "wiring it for CCW."
