How can I slow down RPM on my bench grinder DIY Home

Oct 18 2014 0183 32 Nope Bad for the motor bad for what you re working on You have to reduce the voltage so far to appreciably slow the motor that there s insufficient current supply available for it to maintain speed under load Or the unloaded speed has to be way too high The way it s done properly is by PWM Pulse Width Modulation...

How Speed of a Universal Electric Motor is Controlled

A motor which can be operated either on DC direct current or on single phase AC alternating current is called a universal motorUniversal motors are known to sometimes overspeed when run with no loadThis article explains three different methods of controlling the speed of a universal electric motor and describes what determines the RPM of a universal motor...

Building a speed reduction pulley system Briar Press A

Think of the pulley system as a gear reduction A 2 inch pulley driving a 4 inch pulley reduces the speed in half If you get a 2 inch pulley and a 4 inch pulley on a 1/2 inch intermediate shaft with pillow block bearings on each end mounted on a frame of some sort and drive the 4 inch pulley with the 2 inch on the motor and drive the 22 inch wheel on the press off the other 2 inch pulley...
