Variable Speed Drive Repair
When a Variable Speed Drive (VSD) fails, the impact is often immediate. Production stops, critical processes come to a standstill and maintenance teams are under pressure to restore operations as quickly as possible.
At Fletcher Moorland, we specialise in Variable Speed Drive Repair, Variable Frequency Drive (VFD) Repair, AC Drive Repair, Industrial Inverter Repair and Frequency Inverter Repair, helping manufacturers across the UK minimise downtime and extend the life of their equipment.
Whether you refer to them as Variable Speed Drives, Variable Frequency Drives, VFDs, inverter drives, AC drives or motor drives, our experienced engineers provide a comprehensive drive repair service for industrial applications of every size.

How can we help repair your VSD?
From power module failures and damaged IGBTs to control PCB faults and ageing capacitors, our engineers repair drives at component level wherever practical, delivering a reliable and cost-effective alternative to replacement.
Urgent Repair
Manufacturers we commonly work with:
Unlike many repair companies, we don't simply replace failed components. Every drive undergoes a structured diagnostic process to identify the root cause of the failure before repairs begin.
As an authorised Nidec Drives Systems Integrator and long-standing repair specialist for leading manufacturers including ABB, Siemens, Control Techniques, Danfoss, Schneider Electric, Lenze and SEW-Eurodrive, Fletcher Moorland combines decades of engineering experience with advanced diagnostic equipment to deliver repairs you can trust.
Whether you need an emergency industrial drive repair, a planned refurbishment or advice on whether repair or replacement is the best option, our engineers are here to help keep your industry running.
What is a Variable Speed Drive & How Can We help?
A Variable Speed Drive (VSD), also commonly known as a Variable Frequency Drive (VFD), AC Drive, Frequency Inverter or Inverter Drive is an electronic device used to control the speed, torque and direction of an electric motor.
Rather than running a motor at full speed continuously, a Variable Speed Drive adjusts the voltage and frequency supplied to the motor, allowing equipment to operate only at the speed required for the application. This not only improves process control but can also significantly reduce energy consumption, minimise mechanical wear and extend the lifespan of connected equipment.
Variable Speed Drives are widely used across industry to control:
- Pumps
- Fans
- Compressors
- Conveyors
- Mixers
- Extruders
- Packaging Machinery
- HVAC Systems
- Cranes & Hoists
- Water Treatment Equipment
- Food Processing Machinery
- Automated Production Lines
When a drive fails, these critical systems can quickly become inoperative, leading to costly production downtime. That's why rapid diagnosis, expert repair and thorough testing are essential before returning equipment to service.

We’re not the type of company to just repair a fault then send the VSD back to you, if some components have aged or failed then it could just be a short time later that others do. Our VSD repair process is a full refurbishment. We will replace all components that either have a ‘hard’ fault or those that we know degrade with age. In most cases we will replace with components that have a higher working temperature threshold as we know these will last longer. Typical components are electrolytic capacitors, opto-isolators, relays and cooling fans. All solder joints are reflowed too, as we know this helps to provide a long-lasting refurbishment.
The final critical step is the verification of our repair work. All VSDs are powered up with a suitable motor and are run under loaded conditions. We fortunately have a 350 amp load rig to test all VSDs. Under load, a VSD is working hard, it’s doing what it would on site and all components are being fully tested. It’s only after a satisfactory load test that we will send a repaired VSD back to you. As a verification, a SERVICEview video of the test will be emailed.
4 Simple Steps to Getting Your Variable Speed Drive Back in Action
Nationwide Collection
For most Variable Speed Drive Repairs we arrange nationwide collection using our own fleet of vehicles. Simply tell us the equipment type, fault details, and urgency (we do offer a premium service for Emergency work).
Should we not be able to collect with our own fleet, we work with a number of approved courier suppliers who can collect & deliver your unit to our workshops in Stoke-on-Trent, Staffordshire.
Emergency VFD Repair
Unexpected Variable Speed Drive failures rarely happen at a convenient time. Whether it's a failed conveyor drive stopping production, a pump inverter tripping repeatedly or a packaging line refusing to restart, every minute of downtime can impact productivity and profitability.
Our engineers understand the pressure maintenance teams face when critical equipment fails.
That's why Fletcher Moorland offers a responsive Variable Speed Drive Repair Service designed to diagnose faults quickly, repair drives efficiently and return equipment to service with minimal disruption.
From obsolete inverter drives through to the latest intelligent Variable Frequency Drives, our workshop supports a wide range of industrial applications across manufacturing, food production, water treatment, logistics, rail and energy sectors.
If repair isn't the most economical solution, our engineers can also advise on replacement options, upgrades and retrofit solutions through our partnerships with leading drive manufacturers.
