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.

EV Motors

As electric vehicle manufacturers move toward 600V and higher voltage systems to improve efficiency and
charging speed, the demands on motor insulation have significantly increased – brining with them a greater risk of partial discharge.
OFIL’s UV camera solution offers a precise, non-invasive method to detect external partial discharge activity during surge and Hi-Pot testing, helping manufacturers identify insulation weaknesses early in the process. industry standards
By pinpointing discharge caused by design flaws, material inconsistencies or inadequate insulation layers, our technology helps improve motor reliability, reduce failure rates, and support continuous design improvements.
Integrating UV inspection into the EV motor manufacturing workflow provides a vital layer of quality control that supports both safety and long-term performance in the evolving high-voltage EV landscape.
