Our Repairs and Overhauls services are designed to ensure the optimal performance and longevity of electrical rotating equipment for the rail, transit, and wind generation industries. With a focus on precision, efficiency, and reliability, we provide tailored solutions to restore equipment to peak condition.

Condition-based repairs
We use advanced diagnostic tools to evaluate the condition of equipment and determine repair needs based on wear and performance degradation. This minimizes unnecessary downtime by addressing issues before they lead to failure. Repairs are focused on specific components or systems identified as requiring attention, ensuring cost-effective and efficient restoration.

Catastrophic damage repairs
Our team is equipped to handle severe failures, including those caused by electrical faults, mechanical breakdowns, or environmental incidents. We perform detailed inspections to evaluate the extent of the damage, including structural integrity, winding conditions, and core functionality. Using OEM specifications or custom designs, we repair or replace damaged components to ensure the equipment is restored to its original performance capabilities.

Structured overhaul projects
Our structured overhaul programs involve a comprehensive assessment and refurbishment of equipment to extend its service life and ensure reliable operation. Each project is tailored to the equipment's unique requirements, with a detailed roadmap covering disassembly, inspection, repair, reassembly, and testing. With a structured approach, we minimize downtime and maintain clear timelines, ensuring the overhaul process is seamless and efficient.

Rewind and recoil programs
For equipment with degraded or damaged windings, we offer complete rewinding services, utilizing high-quality materials for in-house built winding kits and precision techniques to restore electrical efficiency. Specialized recoil services are available for critical components, ensuring proper magnetic field performance and alignment with design specifications. By modernizing winding designs and materials, we improve thermal performance, reduce energy losses, and extend equipment lifespan.

Bearing replacement programs
Bearings are crucial to the performance and longevity of rotating equipment. Our programs focus on replacing worn or damaged bearings with OEM replacements.
