AC Motor Repairs

At Mawdsleys, AC Motor repairs aren’t just something we do — they’re what we do best. For decades, businesses like yours have trusted us to get them back up and running fast — with no compromise on quality. We know that when an AC motor grinds to a halt, so does your operation. And that has a knock-on effect that your customers will feel. That’s why our seasoned M&E engineers don’t waste a second. Whether it’s a rapid refurb or a precision motor repair, we turn around your AC Motor within an agreed lead time — no delays, no excuses. From 1kW to over 1,000kW, we handle it all with rigorous quality processes and proven procedures that stand up to the toughest scrutiny. AC motor repairs are our bread and butter.

Full Mechanical and Electrical Inspection

When your AC motor arrives at Mawdsleys — whether delivered by you or collected by our trusted courier network — it enters a process built on precision, not promises.

We log every motor with full traceability under our ISO 9001:2015 accreditation. That means accountability from the moment it enters our facility to the moment it leaves — fully repaired and ready for service.

Our engineers carry out a full mechanical and electrical inspection. We test windings for faults, check resistance and insulation integrity, and if the stator’s compromised, we rewind it to its original spec using only high-grade enameled copper and class-rated insulating varnish. Then we move to the rotor — checking condition, balance, every tolerance to ensure it meets all standards.

To Repair or to Replace?

When an AC motor fails, the clock starts ticking. Do you repair the motor? Or rip it out and replace it? The answer depends on a few critical factors — and getting it wrong can cost more than just money.

Age of the motor: If your AC motor’s been in service for years, it might be time to consider a modern, energy-efficient replacement. But don’t jump too fast — rewinding or repairing an older motor is often faster and far more cost-effective than starting from scratch with a new install.

Use of the motor: The more horsepower an AC motor delivers, the greater the operating cost. If a smaller motor that is used infrequently begins to underperform, the cost to the business may not be substantial, even if the motor is inefficient. In this scenario, motor repair can be a cost-effective solution. If the motor has a bigger output, the cost of underperformance will soon outweigh the cost of a repair or replacement.

Time: A quality AC motor repair from Mawdsleys can be turned around in as little as 24 hours. An AC motor replacement? Between sourcing, shipping, and fitting — that’s more time, more disruption, and more cost.
