Testing a rewound electric motor in our workshop

Electric motor rewinds, repairs and servicing carried out to the highest standards

A 45kW compressor motor repaired by rewinding.
Electric motor rewinds, repairs and servicing are carried out to the highest standards at Westin Drives. Rewinding has been at the core of our business since it was established in 1921.

Cheap new motors have made the rewinding of standard small frame motors almost redundant, but there is still a big demand for the sort of specialist rewind service provided by our experienced engineers. 

​We are SKF Certified Rebuilders, one of a handful of UK companies to be granted this accreditation. Our engineers are also certified EX motor repairers, qualified to carry out flameproof electric motor repairs.

A rewind is often the fastest, most cost-effective solution for even the smallest of motors, as they may have special features such as non-standard shafts and flanges. Rewinding is the only viable option for obsolete motors. Our rewinders have years of experience rewinding AC single and three-phase motors, slip ring motors, DC field and armature, brakes, clutches, solenoids and servo motors.  We can repair motors of any physical size to 3.3Kv. 

To give our customers the best electric motor rewind service, Westin Drives has invested in a portable surge tester. It is used to diagnose problems with windings that arrive for repair and for the final check on jobs before they are returned to the customer. Surge tests are important because of the ability to reveal turn-to-turn insulation weaknesses. Such weaknesses, found at voltages above the operating potential of the device under test, can be signs of an impending motor failure. Surge tests are also used to find shorts and other faults in windings and coils.

Our machine is capable of testing motors up to 12kV. An added benefit is that it can be taken on site for the swift diagnosis of winding problems. In addition, the machine generates a detailed report on the state of each tested winding, which is then provided to the customer.
​
Servo motors are a type worth rewinding should they require it. As they are often bespoke to the machine they drive, replacement by a new motor can involve long lead times and high prices. It takes skill and experience to rewind such motors as even the smallest mistake during the process could lead to failure. We have been successfully rewinding servo motors for many years.
​
We continuously try to develop all aspects of our business. For example, we have changed from dipping rewinds in varnish to a cleaner, better quality, higher temperature-rated epoxy. Stripping out old windings plays a major part in ensuring optimal performance and eliminating premature failures. We use the industry-approved method and use a burn-out oven to remove old insulation, allowing fast removal of old coils and minimising the risk of damage to the stator pack.

CASE STUDY Voltage conversion rewind

THE CHALLENGE: A customer wishes to run his his three-phase planer thicknesser from a single-phase supply. He likes it because it’s an old Wadkin and they’re solidly built. 'They don’t make them like they used to', he says.

THE SOLUTION: As the motor is non-standard, we decide the best thing would be a voltage conversion rewind on the stator to take it from a 415V to a 220V three-phase supply. A single-phase to three-phase inverter would then be fitted.

​Our rewinder is tasked with the job. The conversion is a simple formula, but basically to decrease the supply voltage from 415V to 220V the amount of turns per coil in reduced and the gauge of the wire increased.
