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.
Electric Aircraft Motors
As the electric aircraft industry advances, particularly in motor design, managing partial discharges under varying pressure conditions becomes increasingly critical. Partial discharge is more likely to occur at high altitudes due to reduced atmospheric pressure – a phenomenon explained by Paschen’s Law, which shows that breakdown voltage decreases as pressure drops.
OFIL offers precise, visual solutions for detecting and analyzing external partial discharge in electric aircraft motors. Our UV cameras are uniquely suited for identifying early-stage discharge activity that could compromise motor insulation and performance, especially in low-pressure environments.
The compact and lightweight design of electric aircraft motors, combined with fluctuating pressure conditions, demands advanced diagnostic tools. Integrating OFIL’s UV camera technology into manufacturing and testing processes allows manufacturers to detect PD early, mitigate damage, and gain critical insights into insulation performance and design effectiveness.
By incorporating UV inspection tools, manufacturers can enhance motor quality, safety, and reliability – essential for the evolving demands of electric aviation.
