What Our Customers Say

For over twenty years our association with Priest Electric has and continues to be a great relationship. We appreciate the professional work performed, the products we have bought and the training and special service given by Lee and his staff.

Jerry Wilks, Round Mountain Gold, Round Mountain, Nevada.

We are very happy with the customer service, motors and the machine shop at Priest Electric. We get visits at least once a week to make sure all our needs are being addressed. We always get help locating motors or parts in rush situations. The machine shop at Priest Electric caters to us during machine break downs which is very much appreciated by us and our customers.
We thank Priest Electric for all they do for us.

We've tried the other guys in the past, and regretted it. Priest Electric always delivers above and beyond our expectations. They are top shelf in my book, and I'm happy to be working with them.

Electric Motor Frame Sizes

When electric motors began to be standardized by NEMA, one of the first standards released was motor frame sizes.

There are three generations of motors:

  • Original (pre-1952)
  • U Frames (1952-1964)
  • T Frames (1964-Present)
