    Would this variable speed controller work?

    I don't see why it wouldn't, but never hurts to ask. Would this speed controller:

    Work on this motor?

    The router controller will not work with an ac motor. The way it works( at least on a belt grinder) is that the motor is a 3 phase and the controller converts it to a single phase with variable speed. Basically it is a variable speed phase convertor. The router control is a single/single phase speed controller.

    Colin,

    I can not see why this speed controller would not work.
    Your motor is 120volts and 6 amps.
    The speed controller you are looking at will operate a 120 volt motor not in excess of 20 amps.
    Your motor is right in the parameters of this controller.
    The only down side is there is only 3 speed you can use from this controller.
    If I were you I would look at getting a variable speed controller for a ceiling fan.
    Just make sure it is rated for 6 amps or better.
    A rotary dial type will give you a full range of speed adjustment plus you can probably pick one up at your local hardwear store.

    Ok, maybe not hardware store but electrical wholesaler will carry a speed controller for an industrial ceiling fan. I checked quickly on the Internet and they definatley make some that are rated to handle a 15 amp load.

    I believe this type of VFD is to be used with motor with brushes, like router or drill motor. For your regular AC motor, fan controller is likely to work (fan uses a small AC motor).

    Regardless of which motor is being used I believe this controller will still work as long as it is 120volt motor. Just because a motor has brushes does not make it operate different from a standard 120 volt motor. 120volts is 120volts.

    It will slow the motor down but will also result in a lose in power making the motor unable to be used on anything other than the smallest loads. So the big question is--What are you going to do with this combination?
