Electric Motor Repairs, Maintenance & Overhaul
Houghton International offers a wide variety of electric motor repair, overhaul and maintenance services, on-site or in our specialist workshop.
Electric motor repair
Our electric motors repair services are here to get your motor up and running again, whatever the size, power or application. At Houghton International, our expert team provides electric motor repairs, maintenance and overhauls for all types of motors in a wide range of sectors and industries, on a contracted or emergency response basis.
In case of a sudden unexpected failure, we offer 24/7 emergency repairs to help minimise downtime and have your motor back in service in as short a timescale as possible. Where required our site team can also carry out decomissioning, removal and transportation to our workshop, as well as installation and recomissioning following repair.
If the motors can’t be removed from site, our site services team can carry out some repairs in situ, nationwide.
Electric motor overhaul
A standard electric motor overhaul includes an initial equipment inspection and diagnosis, bearings replacement, a test run and report.
A sample motor overhaul work scope includes –
- Collection from site
- Inspect and record all relevant data from the nameplate
- Carry out electrical and mechanical check tests to verify motor condition and any reported faults, where possible
- Dismantle motor
- Clean and inspect all component parts
- Datum checks, including bearing journals and seatings, shaft extensions, shaft extension run out, shaft seal fits, commutator diameter, and brush surface length
- Repair or replacement of defect components and parts
- Steam cleaning, stove drying and varnishing of stator and rotor windings as specified in IEEE 1068
- Rotating parts dynamically balanced to ISO grade 2.5 or better
- Up to date motor plate fitted before dispatch
- Delivery service to customer site and recomissioning
Following our industry-verified quality processes and operating procedures, all details of our work are recorded on a detailed job card throughout the overhaul process and logged on our digital ERP system. This controls the quality of the overhaul and allows us to build a history of the motor for future reference.
If we detect the need for repair beyond the scope of the overhaul, these will be reported and a quotation provided. Upon approval, our experienced engineers will carry out the work on a standard or emergency basis in line with your requirements.
Electric Motor rewind
We specialise in complete electric motor rewinding and our engineers are capable of re-engineering and upgrading electric motors efficiency and reliability. All motors are wound to Class F or higher thermal class, upgrading the insulation quality where beneficial to our HiFLEX coil design. To learn more visit our electric motors rewinding services page.
Preventative Maintenance and Emergency Repairs
We provide a preventative maintenance service that includes regular checking and fault prevention for your motors as well as emergency repair needs.
Compliance
Houghton International fully complies with IEEE 1068 specification Clause 2 in relation to electric motors overhauls. Our workshop is EASA accredited, meaning that Houghton International has successfully demonstrated its compliance to EASA AR100 and follows the prescribed good practices to consistently deliver quality electro-mechanical repairs that maintain or improve efficiency and reliability.

A electric motor can be repaired, however an inspection would be required to identify whether this is economically viable. Having your electric motors repaired may be the quickest and most cost-effective way to getting your operations going again, not to mention that it’s often more environmentally friendly than replacing with new. We can work with your operations team to determine the best course of action and to get your motor to usual operating conditions.
This largely depends on the size, damage to the motor and your priorities. Some smaller motors are more economical to replace however there might be a long waiting period for a new motor. Motor repairs can have a quicker turnaround time, and can be a more efficient, eco-friendly solution. Our engineering team can help you assess which is the best option for you.
There are many causes of motor failure. Some causes include overheating, surge voltages, poor ventilation, poor alignment, lack of lubrication, excessive moisture and loose connections. An inspection of the motor can determine what could have caused the failure and how to prevent it happening in the future.
Yes, older motors may be fixed or reconditioned. Old motors may no longer be manufactured so replacing them isn’t an option. With technology like 3D laser scanning and printing capabilities along with extensive reverse engineering capabilities, Houghton International are able to restore old motors to continue your operations.
The cost for a motor rewind largely depends on its specification and voltage. We will always aim to identify the solution best suited to your needs. We recommend reaching out to us so that we can provide you with and initial quotation for your motor rewind.
