Electric Motor Repair & Rewinds


Getting the most from your electric motors

Specialising in electromechanical engineering, Houghton International’s services include mechanical and electric motor repairs to a broad range of equipment including AC and DC motors, pumps, gearboxes, generators, turbines and transformers.

We provide a comprehensive range of mechanical and electrical repairs, overhaul and rewind services for electric motors and generators in a range of sizes and brands, with handling facilities up to 40 tonnes.

Our electric motor repair and rewind services cover a wide range of electric motors, including random wound stators and armatures, and non-standard soft coil and preformed high voltage coils. We also carry out rotor and stator rewinds on motors and generators and have specialists in gearbox and pump repairs in house.

As specialists in EX hazardous area motor repairs, we have experience in the repair and overhaul of hazardous area equipment and also experience with submersible pump motors, water and oil filled motors.

We provide ad hoc repair and maintenance to tight turnaround and schedules, deliver volume, planned maintenance programmes and pioneer industry-leading solutions with the objective of maximising plant efficiency and reliability whilst minimising costs and machine downtime.

AC DC Motor Generator Rewinds and Repairs - Houghton International

Our services range from standard inspections and overhauls to complete electric motor rewinds. In addition, our engineers are capable of re-engineering and upgrading electric motors to be more efficient and durable. We operate a 24-hour call out 365 days of the year to ensure we are always available when needed.

Work is carried out by an experienced team of multi-skilled electromechanical engineers on customer’s premises or in-house in our purpose-built workshop. We have burn off, Vacuum Pressure Impregnation (V.P.I) facilities and in-house coil manufacturing capabilities to speed up

We carry out extensive electrical and mechanical light run testing of the overhauled assemblies using 415 to 1000V to rotate the motors, whilst carrying out measurements of vibration analysis and alignment checks, to ensure the serviced/overhauled motors meet a high-quality standard.

Additionally, during electric motor rewinds, we individually test all windings and the full motor winding using Baker Test equipment to fully test and verify all electrical components for Megger (IR), resistance of connections, Hipot/Flash, interturn surge test, Polarisation index, phase line to line and line to ground testing.

Houghton International complies with and in some areas exceed IEEE 1068 specification and have controlled process and records in place to manage the rewind process. All motors will be wound to Class F or higher thermal class, upgrading the insulation quality where possible to our HiFLEX coil design.

Our workshop is EASA accredited, meaning that Houghton International has successfully demonstrated that it complies with EASA AR100 and follows the prescribed good practices to consistently deliver quality electromechanical repairs that maintain or improve AC electric motor efficiency and reliability.

We also offer preventative maintenance services, which include motor management, condition monitoring, vibration analysis, laser alignment and thermographic imaging.
