Reducing RPM on RPM Single Phase Electric MotorReducing speed on a rpm motor with pulleys Tools

Aug 09 32 I m trying to figure out the cheapest yet most efficient way to reduce the RPM output of my electric motor from RPM to 60 RPM Is this obtainable with a V Belt pulley design I know it s possible on paper but would this be safe/realistic I was also looking into worm gears but Oct 15 32 Im looking at a coote grinder and Ive noticed that he recommends a rpm motor for the 8 and 10 contact wheel modelsI have a nice rpm craftsman motor with built in switch and overheat protection alreadyProblem is its a rpmCorrect me If Im wrong but couldent I use a 2 pulley on the motor and a 5 pulley on the grinder to reduce my speed to the proper range

Grinder speed control Canadian Woodworking and Home how to decrease motor speed of grinder

Aug 30 32 Re Grinder speed control I think it can be done but you need a speed controller designed specifically for induction motors It would likely be cheaper to buy a new grinder Also it s not good for the motor and could over heat it There are speed controllers for ceiling fans which have induction motors but it s a different type of wiring then a grinder motor and it s built for that proposehow to decrease motor speed of grinder Johnson Outboard Motors How To Information eHow Don t just sit there scratching your head find useful info on Johnson Outboard Motors on eHow

Motor RPM issue or VFD on food grinder how do I slow the revs on an angle grinder for polishing

Jan 09 32 The physical size of the frame won t allow for a larger pulley on the grinder so I thought of using a gear motor With a 2 1 ratio the gear motor still doesn t have enough torque SO I m wondering if using a VFD on the Leeson motor will decrease it s torque value and/or RPM when you dial it down to a reasonable RPM which is around 100 RPM If you try to reduce the speed with some current reduction device on the grinder then the motor will not have the torque necessary to drive the polishing pad the resistance on the motor can cause that to burn out The reduced speed of a polisher is obtained through gearing
