Ingress protection
Discover unparalleled peace of mind with the WE series, which offers a superior standard protection level of IP55. For those with specific needs, we proudly offer tailored solutions that elevate protection to IP56, IP65, IP66, and beyond. Trust in our ability to safeguard your equipment from potential threats.
The essence of our premium protective shell lies in its meticulous design to shield against electric shock and prevent contact with live or rotating components. Additionally, it diligently guards against the intrusion of solid foreign elements, water, and oil, ensuring no detrimental effects occur. The following codes and meanings outline our diverse protection standards.

Code	Meaning	First numeral	Meaning	Second numeral	Meaning
IP	Level of protection	5	Dust prevention	5	Protected against water spray (12.5L/min @ 0.3 bar)
		6	Dust tight	6	Protected against water jets or heavy seas (100L/min @ 1.0 bar)

Cooling method

The WE series is engineered with cutting-edge F-class insulation, with its temperature rise evaluated based on B-class standards. For those operating in demanding environments, we offer the option of nano-insulating impregnation resin, which substantially prolongs motor life even in challenging power and usage conditions.
For optimum reliability, our motors utilize advanced insulation materials to separate live components from each other and the shell. The lifespan of these materials is deeply intertwined with both their insulation grade and operating temperature. As motors operate as energy or signal converters, they inevitably produce heat. Our design ensures that temperature rises remain within established bounds, guaranteeing that even with energy losses, the motor functions seamlessly within its designated limits.
