re: Help

What do you mean when you say you had the motor “converted to 220”? A motor that is not designed to run on 220V cannot be made to run on 220V. There are motors that are designed to run on either/or depending on how certain connections are made. Is the motor designed to run this way? Also, as rjgray asks, is it plugged into a true 220V outlet?
Changing the plug on a motor designed to run on 110V to adapt it to a 220V outlet can lead to all kinds of bad things happening. Since the motor runs, it may well be designed to run on 220V, but may be wired incorrectly internally.
Some 220V motors will try to run on 110V, but you will permanently damage the motor by overheating the windings.

So,
1) Make sure the motor is designed to run on 220V. The operating voltages should be stamped on the motor plate.
2) Using a multimeter, check the supply voltage at the plug for 220V. There should be 3 prongs. One will be ground. Measuring each of the others to this prong will read 110V . Reading across the other two will show 220V. If it doesn’t, something is wrong.
3) Confirm that the motor is wired correctly for 220V.

What type of saw is it?
