Diagnostics and maintenance for reliable operation

As HV and MV motors operate under increasing electrical and mechanical stress, early issue detection is critical. Our diagnostics identify emerging faults, while our maintenance services preserve asset condition through planned and preventative programs, including inspection, testing and routine servicing such as vibration analysis and partial discharge testing.

Your benefit: Reduced risk of failure and extended asset life through early detection and proactive maintenance.

Specialist engineering for complex motor systems

With increasing technical stress and failure risk, our in-house engineering teams develop tailored solutions to manage key failure mechanisms. We prioritize repair before replacement to improve reliability and extend asset life, supported by advanced engineering capabilities including health assessments, root cause analysis (RCA), design and repair, reverse engineering, retrofits and upgrades.

Your benefit: Improved reliability and longer asset life through tailored engineering solutions that address root causes and optimize performance.

Comprehensive repair, rewind and field service capability

We restore HV and MV motors to reliable operation through expert repair and rewind services - often saving assets others would replace. Our capabilities include mechanical and electrical repairs such as shaft repairs, slip rings, welding, machining and full component restoration, alongside rewinds that restore electrical integrity and extend asset life, with responsive on-site support when needed.

Your benefit: Reduced downtime and extended asset life through complete repair, rewind and field service support.

In-house coil and bar manufacturing

Precision-manufactured coils and bars are critical to the performance of large, high- and medium-voltage machines. Our in-house manufacturing ensures consistent quality and reliable operation under high electrical, thermal, and mechanical stresses. It is supported by advanced insulation systems including VPI and resin-rich technologies, with large-scale VPI capability in the US supporting ultra-large applications (15 ft tank). All coils and bars are manufactured under strict quality and document control.

Your benefit: Reliable performance and reduced risk through high-quality, in-house manufactured coils and bars, with tailored insulation systems and responsive delivery.

Secure storage and critical motor readiness

Planned asset management is key to reducing risk and downtime. Our secure, temperature- and humidity-controlled storage facilities in Falkirk, UK and Alvin, TX, USA operate to recognised industry standards, ensuring high-voltage and medium-voltage motors are preserved, maintained, and ready for rapid redeployment when needed. Services include short-term and long-term storage, preservation, inspection, and periodic testing to maintain operational readiness.

Your benefit: Reduced downtime and rapid deployment with stored, preserved, and fully tested motors ready when needed.

Repair or replace, the right decision

For large HV and MV motors, repair is often the preferred option, but replacement may be required depending on condition, availability, and operational requirements. We provide clear, independent guidance to support repair or replacement decisions, including technical assessment, cost comparison, and lifecycle considerations. For customers in North America, our motor distribution business ensures the right motor is available, ready to go when needed.

Your benefit: Better-informed decisions balancing cost, risk, and long-term performance, with access to replacement solutions when needed.
