Hi,
Here’s a simple job taking less than an hour to do. My home made belt grinder motor proved to be poor at starting although it ran well once the drive belt had been given a tug in the right direction.
This morning I removed the motor which is a common ¼ HP single phase 1425RPM type and stripped it to reveal the centrifugal switch. With a quick clean of the contacts and lubrication of moving parts including the bearings it was re-assembled and now works much better.
Before stripping an electric motor I always centre pop the motor main body and end covers adding two pops to one side and three to the other; this ensures it goes back together correctly.
I wonder how many such motors have been scrapped just for the need of a bit of work. Once the weather warms up I’ll completely dismantle the grinder and give it a decent spray painting job.
Kind regards, Col.
