Electric Motor Repair & Overhaul

Electric motor repair

Our electric motor 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 motor 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 motor 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, bearing replacement, a test run and report.

A sample 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 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 repairs beyond the scope of the overhaul, these will be reported to the customer and a quotation provided. Upon approval by the customer, our experienced engineers will carry out the work on a standard or emergency basis in line with the customer’s requirements.
