Motor conversion 220 to 120
Hello,
I am considering buying a 220v dust collection sys from a friend. I do not have 220v in my house (other than the dryer) and would rather not wire for just the dust collector. Can I convert the existing motor to 120? If so any ideas how?
Thank you.
Happy and safe holiday season to all!

Its very likely that you will be able to do this. You need to look at the nameplate on the motor for its voltage requirements. If the motor can be wired 120 volt the voltage block on the nameplate will have 120/240 or 115/230. If it shows 120 volt then a wiring diagram is commonly present it the wiring enclosure (sometimes on the inside of the cover plate) of the motor or there will be a diagram of the connections for 120 or 240 on the name plate itself. If no wiring diagram is present and it says 120/240 on the nameplate of motor of the dust collector then you will have to have the owners manual or contact the manufacturer for wiring instructions.
Also when you convert to 120 you will double your amps required for the motor. This may or may not have an impact on whether you will be able to use this on a typical 120 volt 15 amp or 20 amp circuit in your home. It will depend on the horsepower of the motor.

To emphasize what Roger said: When you convert this motor to 120 (if you can convert this motor to 120) you will double the amps required. Generally, if this dust collector was set up for 220, it probably requires enough power that it will need its own circuit, either at 120V or 220V. This means that you will probably have to run a new wire for this dust collector, and if you are doing so, you might as well make it a 220V circuit.
However you should look at the nameplate for the motor, and see if a) it can run at 120 and b) what the amp requirement will be.

You will (most likely) need a dedicated circuit for this unit at either voltage, so you should leave it at 240 volts unless you have a specific reason not to.
