I like to do bench grinders

Today I will show the beginning of work on a disk grinding machine. It will be with a 750-Watt motor. 1400 revolutions. Grinding discs 180 mm. Here are a few photos.

to be continued.

 

So work on these machines came to an end. As always, there are few photos of some parts.

I am unclear how you are making 3 phase motors run on single phase ? Are you using capacitors to shift the phase over?

 

Good afternoon. I use a capacitor. Starting capacitor 150 Microfarad. Working capacitor 30 microfarads. Here are some diagrams.

 

All circuits are checked by me. Work well.

 

Really nice. Very quiet. Nice use for spare motors.

You should have a go at making a small surface grinder next

 

I’m making a new machine with such an electric motor. 380 volt electric motor. 1400 revolutions. 550 watts. It will be a machine tool for two steel disks. Grinding. Next photo of the electric motor.

 

I would like to know how to "do" a grinder?

 

When I do this work, Disc Grinder will then be something else.

 

Thanks for the electrical diagram ! I'v got a couple three phase motors in the basement I'l try this on .

 

This is what the machine will look like
