This question may be in the wrong section/forum/site but I am lost trying to work this out.
I have a motor rated to .66hp and 940rpm which needs replacing. The motor I am replacing it with is 1.5hp and 2850rpm. Its used to run an old saw via belt and pulleys. I can get the rpm of the larger pulley near enough where it needs to be using a pulley on the motor 35% of the size of the original, but the increased HP will probably cause the belt to slip, plus it means finding a specific pulley for a motor from 1960.
If I use a variable resistor of some kind, I could slow the RPM down to the speed of the original, but I cannot work out what that will do to the HP.
Any help would be appreciated,
Jordan
