How It Works

There are a variety of reasons that can cause the failure of an electric motor. Our technicians have the know-how and over 30 years of experience repairing AC and DC motors from a wide range of models, brands, applications, so whatever the problem with your motor, we have probably come across it before. Our workshop is available 24 hours a day, so we are well placed to complete your repair quickly and efficiently.


Once your AC motor or DC motor has been received, our team undertakes a detailed investigation into the cause of the problem. This will include a range of electrical and mechanical tests, before providing a repair report to advise the fault (if any), repair required, repair cost and delivery time.


If we receive your approval for repair, we will start carrying out the works based on our initial repair report. The typical turnaround time for a motor repair is 4 - 5 working days. However, we can often offer a faster service for critical motors on request, sometimes completing the same within 2 - 3 hours of receiving the motor (this will be dependant on the fault).


When the required motor repair has been completed, our experienced engineers carry out detailed tests using specialist equipment, giving you the peace of mind that the repaired motor meets the standards you would expect.

AC Motor Repair

​An AC motor can have one, or several, faults. The problem(s) could be electrical and/or mechanical. If it is electrical, it can be within the windings or in auxiliary parts (if fitted), such as feedback devices including resolvers, encoders and tachogenerators.

AC motors can also have brake assemblies and force vent fans. These extra features on the motor can also have electrical faults. If the fault is the result of mechanical failure or mechanical wear, this could include damage to the bearing journals, bearing housings, shaft, or elsewhere.

Thanks to our extensive in-house facilities, we can test all aspects of AC motors and provide you with a cost-effective solution to quickly get your machine back into production.

DC Motor Repair

DC Motors can also have electrical and/or mechanical faults. This type of motor has an armature, along with a permanent magnet stator or field windings. We have experienced engineers in-house to carry out rewinds of the armature and/or field if required.

Similar to AC motors, DC motors can also be fitted with auxiliary parts such as feedback devices, brakes and fans; all of which can present their own electrical faults. Mechanically, the most common wear on a DC motor is the commutator, which requires servicing (the frequency of the service will be dependent on the use of the motor).

Our machining facilities allow us to service and repair even the largest commutator without any issues.

1-Year Warranty On All Repairs

The Alpha Electrics 1-year Warranty on all servo motor and servo drive repairs gives you peace of mind and reassurance in the work we carry out on your servo motor and/or servo drive. In the unlikely event of a fault relating to our repair, you can return it to us free of charge and we will resolve the issue immediately.
