Electric motor rewinds
At IPS, we comply with – and in some areas exceed – IEEE 1068 specification for electric motor rewinds and have controlled procedures and records in place to manage the electric motor rewind process. All electric motors are wound to Class F or higher thermal class, upgrading the insulation quality, where beneficial, to our HiFLEX coil design.

IPS’s facility encompasses over 120,000 sq ft of purpose built engineering space, ideally located for national and global transport links.
The Ronnie Mitten Works houses everything needed for motor rewinds and repairs, including in-house coil manufacturing facilities and a dedicated winding bay.
Our adjacent Large Machine Shop offers 40-tonne craneage and 13 metre working height, with 15,000 sq ft dedicated to larger machines and specialist projects.
Work is carried out by an experienced team of multi-skilled electro mechanical engineers on customer’s premises or in-house in our purpose-built workshop.
We have burn off and Vacuum Pressure Impregnation (VPI) facilities as well as in-house coil manufacturing capabilities for absolute control over quality and lead times.
Fully experienced in the rewind of a wide variety of electric motors in a range of voltages, with both soft and preformed coils, we routinely rewind more complex motors such oil and water filled motors and large machines.
Houghton International supplies a range of coils specifically designed for the repair market, including HiFLEX – our fully cured, fully tested, totally flexible insulation system for improved fit, quicker installation and reduced risk of damage.
Manufacturing our own coils helps us provide the quickest and most cost-effective service alongside full quality assurance.
In many cases, motor rewinding is also more cost-efficient and environmentally friendly, as the stator housing, rotor and shafts are retained and reused. This significantly contributes towards the circular economy, minimising waste through reusing, repairing, refurbishing and recycling existing materials and products.
