Rotating Machines
Manufacturers and service providers of electric motors and generators operate in a market where performance, reliability, and safety are non-negotiable. Whether producing new machines, overhauling used units, or developing advanced EV motors, early detection of insulation defects and partial discharges is essential to ensure long-term durability and compliance with industry standards. OFIL provides inspection solutions designed for the needs of rotating machine applications. Our UV inspection technology enables accurate pinpointing and visualization of external partial discharge (corona PD and surface PD) activity – issues that can compromise winding insulation, reduce operational life, and lead to unexpected failures. From OEMs and coil manufacturers to repair workshops and EV developers, OFIL’s tools help identify problems early, streamline quality control, and support efficient maintenance practices.
Windings & Coils
For manufacturers of stator and rotor windings, maintaining high insulation integrity is essential to delivering reliable, long-lasting components.
OFIL’s UV inspection technology enables precise detection of external partial discharge during the design, manufacturing, and QA stages.
By identifying discharge caused by improper corona grading, insufficient insulation coating, or localized surface defects, manufacturers can catch potential issues before coils are installed into machines.
The ability to perform fast, non-contact inspections directly on the factory floor helps improve production quality, reduce returns, and ensure compliance with high-voltage performance standards – supporting both process efficiency and end-user trust.
