Slowing down the Jet 1442
I believe that the Jet 1442 motor is a standard type induction motor. This
type of motor is frequency dependent - it's speed is governed by the power line frequency. Trying to reduce the voltage being fed to it won't change the speed until the motor's power reduces to the point where it doesn't have enough power to keep up with the power frequency. If a load is applied and the motor cannot rotate at the speed governed by the power line frequency the motor will likely overheat and burn up very quickly. If you want to change the speed bad enough you can either buy a 3 phase motor and a variable frequency drive to run it, or a DC motor and a DC (direct current) power supply for it. Either way you will be spending hundreds of dollars to get this capability. Charley "Jimbo" wrote in message ... I was wondering if it is possible to in any way to slow down the motor on the Jet without damage to it. It would be possible to make a "souped up light dimmer" which is very doable but will it cause damage to the motor? After getting into turning I wish I would have bought a lathe that goes slower for larger pieces. Jimbo |
