    motor rotation question

    Hi folks! Pop needs some help. I bought 3 motors from WT Tool. The price was right. The problem is they only rotate clockwise. I designed a jackshaft to reverse the rotation. This rig saps power. Here is the question: if I rotate these motors 1800 will the shaft rotate counter clockwise? Nothing will change but the orientation of the motor to the power tool. I found out that most power tools need a counter clockwise rotation.

    Re: motor rotation question

    Pop, usually you can swap supply wires on your motor to change the direction. Can you post a picture of the rating plate?
    There's never enough time to do it right, but there's always enough time to do it over.

    Re: motor rotation question

    ​No Jason, There is no way to reverse rotation by swapping supply wires. That's the reason I got these motors for $50 each. They were made for HVAC use.
    I designed a jack shaft system to provide a counter clockwise rotation. The jack shaft design is simple, motor pulley to jack shaft pulley, jack shaft pulley to machine. The system saps power from the 3/4 hp. motors. My idea is if I turn the motor 180 degrees I will have a counter clockwise rotation.

    If the motors are PSC (permanent split capacitor,) then they are reversible. These motors usually have a 2 - 5 MF run capacitor, externally connected to motor thru two brown leads. Because they are PSC, they don't have start switches. You remove the end bells, turn rotor around in case and reverse the end bells. These motors don't come with any kind of mounting plate, as they are held in by either bolts thru end bells, or and clamps. A picture would be worth a thousand words.
