Industrial AC & DC Drive & Inverter Repair | Newcastle
For manufacturing, offshore, marine, and oil & gas clients across the UK
When a drive fails, production stops. Northern Power Electronics is an ISO 14001 certified industrial electronic engineering company and NOF member, based in Newcastle upon Tyne.
We repair AC drives, DC drives, and inverters at component level identifying the root cause of failure, not just replacing the board. We serve manufacturing, offshore, oil & gas, marine, and heavy industrial clients across the UK.

Don't see your brand? Contact us — if we have not repaired it before, we will tell you honestly. We repair drives from any manufacturer, including legacy and discontinued models no longer supported by the OEM.
Our Drive Repair Process
AC drives & variable speed drives (VFDs)
DC drives & thyristor motor controllers
Servo drives & servo amplifiers
Soft starters
High-frequency inverters
Drive control boards & gate drive PCBs
Power boards & rectifier sections
Obsolete & discontinued drive units
If your drive model is out of production, that is where we are most useful. Component-level repair means we work on the board itself — not a swap-and-bin approach. We repair drives from any manufacturer, including units with no schematics or discontinued support.
Sectors we repair drives for
Marine & Offshore
Oil & Gas
Wind Energy
Manufacturing
Crane & Hoist
Food & Beverage
Water & Utilities
Heavy Industry
Cost
A component-level repair typically costs 20–50% of the price of a new unit — sometimes far less for high-power drives.
Lead Time
New drives can take 8–20 weeks on back order. A repair is often completed in days, not months. Less downtime, faster return to production.
Obsolete Equipment
If your drive model is discontinued, there may be no direct replacement without costly system redesign. Repair keeps the original running.
Configuration Preserved
Your existing drive holds critical parameter settings, custom configurations, and firmware tied to your process. A repaired unit keeps all of this intact.
Sustainability
Repairing a drive keeps it out of the waste stream. It is the lower-carbon option and extends the working life of your existing equipment.
Previously repaired — and failed again?
We regularly receive drives that have been repaired elsewhere and stopped working again. Our process includes a full root cause investigation before any work begins. We find why the unit failed, not just what failed. That is the difference between a fix and a patch.
Offshore & Subsea
Drive repair for platforms, ROVs, and marine equipment. Obsolete units repaired where replacement lead times are unacceptable.
Oil & Gas
Hazardous area and zone-rated drive repair and refurbishment for oil and gas operations.
Marine & Shipbuilding
AC and DC drives for vessel propulsion, crane, and auxiliary systems. Flexible pricing and terms for marine operators.
Wind & Renewables
Inverter and converter repair for wind turbines, including drives that have failed in service and require full root cause diagnosis.
Manufacturing & Production
Conveyor drives, process line inverters, CNC and machine tool drives across all manufacturing sectors.
Crane & Hoist
DC crane drives, brake controllers, and inverter units for lifting and material handling equipment.
Water & Utilities
Pump drive repair and inverter refurbishment for water treatment and utility operations.
Food & Beverage
Drive repair for washdown and hygienic environments where reliability and fast turnaround are critical.
Heavy Industry & Construction
Drive systems for heavy plant, processing equipment, and industrial machinery across demanding environments.
Frequently Asked Questions
1
Can you repair obsolete AC or DC drives that are no longer manufactured?
Yes. This is one of our most common requests. When a drive model has been discontinued, finding a like-for-like replacement is often impossible without significant system changes. We work at component level, so we can repair the board regardless of whether the manufacturer still supports it. If parts are no longer available, we source alternatives and advise you honestly on the options.
2
How long does a drive repair take?
Most repairs are assessed within 1–3 working days of arrival. Standard repair and return is typically 5–10 working days depending on component availability. If your situation is urgent, contact us to discuss priority turnaround — we will always be straight with you about what is achievable.
3
Do you offer a warranty on repaired drives?
Warranty terms are confirmed at the quotation stage and depend on the nature of the repair and the condition of the unit when it arrives. We are transparent about what we can and cannot cover before any work begins — you will not receive a surprise when it comes to terms.
4
What happens before you start the repair?
We assess your unit and provide a clear quotation before any repair work begins. You decide whether to proceed based on that quotation. We will always tell you honestly if we believe the repair is not worth pursuing — we would rather give you an accurate picture than take on a job that will not deliver value.
5
Can you repair the drive boards themselves, not just swap them?
Yes — and this is what sets us apart. We repair at component level, which means we diagnose the failed part on the board and replace it. We are electronic engineers, not parts swappers. This approach is more cost-effective and produces a more reliable outcome than board replacement in most cases.
6
Can you repair drives from offshore or marine environments?
Yes. We regularly work on drives from offshore platforms, marine vessels, and other harsh environments where salt, moisture, and contamination are a factor. We clean, treat, and repair the unit before testing. If contamination damage is beyond repair, we will tell you clearly before you incur costs.
7
My drive has been repaired before and failed again — can you help?
Yes, and this is more common than you might think. We carry out a full root cause investigation before touching anything. We find the actual cause of failure, document it, and repair it properly. If there is a deeper issue contributing to repeated failures, we will tell you.
8
Do you offer flexible pricing or terms for marine and offshore clients?
Yes. We understand that marine operators and offshore contractors work to different commercial cycles. We are happy to discuss pricing, payment terms, and turnaround requirements on a job-by-job basis. Contact us to talk through your situation before committing.
