Electric motor rewinds, repairs and servicing carried out to the highest standards
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 engineers 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. This sophisticated device is employed to diagnose problems with windings that arrive for repair at our Huddersfield Service Centre. It is also used for the final check on all finished jobs before they are returned to the customer.
Surge tests are important because they are the only ones capable of revealing 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 and since moving into our new purpose-built service centre in Huddersfield we have changed from dipping rewinds in varnish to a cleaner, better quality, higher temperature-rated epoxy. As a result, we are now using class H insulation as standard on all our rewinds.
Stripping out old windings correctly plays a major part of ensuring optimal performance and eliminating premature failures. We use the industry-approved method and put our rewinds in the burn-out oven. This burns off all the old insulation from the windings, allowing fast removal of old coils fast and minimising the risk of damage to the stator pack.
Many rewinders use lamps to apply a flame to the windings, a dirty and time-consuming technique which greatly increases the risk of damage to the stator pack.
