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.
MV/HV motors and generators
OFIL’s UV cameras provide a powerful tool for identifying external partial discharge in large electric motors and generators- whether during OEM design validation, manufacturing quality assurance, or routine overhauls.
Partial discharge, which occurs in stators and rotors due to insulation degradation, contamination or design flaws can compromise equipment reliability if left undetected. By accurately pinpointing discharge activity on stator coils and other critical components, the technology helps prevent costly insulation damage, reduces the risk of unexpected failures, and supports long-term machine reliability.
Workshops benefit from fast, non-invasive diagnostics that eliminate the need for blackout tests, while field teams can perform safe, remote inspections at customer sites. The ability to spot defects early allows manufacturers and service providers to optimize maintenance, reduce downtime, and extend the operational life of high-value rotating equipment.
