Vehicle drive systems

Motor, as the “heart” of new energy vehicles, its technological innovation directly drives the green transformation of the industry. Permanent magnetization, high-speed, oil-cooled flat line, integration, miniaturization, lightweight, high efficiency, high power density and other objectives have achieved significant results. For insulation, the core need remains to isolate conductors from each other or from the iron core through high-performance insulating materials.

Sui On insulating occupies an important position in the field of motor insulation with a wide range of proven products and the ability to develop new solutions quickly:

With NOMEX® aramid paper, NOMEX® aramid paper and polyimide film, they offer excellent thermal, mechanical and chemical protection, as well as excellent breakdown voltage performance.

Responding to added demands: Accommodating chemical resistance (NSN) for cooling media (ATF), improved partial discharge resistance for 800V high-voltage systems, and higher thermal conductivity requirements, for example SOFLEX NSN laminated paper and PEEK materials.

Sui On insulating is committed to providing high-quality insulation solutions to the new energy vehicle industry in order to promote the continuous innovation and development of motor technology.
