    Properly sized sheaves and belts. You can get any speed you want to end up with.

    I want to directly couple motor to pump
    No great load on the pump, and will only be used intermittently

    Gear motor. Much more expensive than buying one already at speed desired.

    OK, now I am a bit confused...

    A DOL will alter voltage/current to help a motor start, a synchronous motor needs a mechanical assit to start rotating.

    How does your DOL work with this motor?
