Let’s say you’ve got an 160kW electric motor that needs a rewind. You are either going to send it for a rewind or replace it. Does the environment or circular economy play a part in your decision?

A motor repair with some interesting UK engineering history
Recently, there was a great deal of interest in an article I wrote about the resurrection of a DC motor. This reminded me of a much more interesting recovery and refurbishment of a DC motor.

I’ve had 35 years in and around the motor repair business and this was …
Everyone knows the importance of core loss testing, but why do so many rewinders dismiss it?
“One of the most important quality assurance tools in the motor rewinding trade is the core loss tester Websites and promotional material from electric motor rewind companies from around the world tend to push one message “Quality Electric Motor Rewinds”, after all, nobody is going to admit to being sub-standard in a competitive industry. But what amazes me, is how …
A small UK engineering company, an ABB inverter and a redesigned control system
How over £500,000 was saved when an already obsolete unit became……more obsolete! Obsolescence is an issue in industries there’s no getting away from it, however, there are many ways to tackle it.

What is a Star Delta Motor Starter?
A 3 phase electric motor has 3 coils. These coils can be configured or connected either end to end (as a triangle) in Delta configuration or with 3 ends together as a Star. Why use 2 types of coil windings? If a stationary electric motor were started directly in Delta mode the current drawn would be very high. To handle this …
