Advanced Ingress Protection
Standard with an IP55 protection grade, the WE series motors can be customized to meet IP56, IP65, IP66, and beyond, catering to specific customer requirements for enhanced safety and performance.
The motor shell protection level is meticulously designed to safeguard against electric shock, prevent proximity to live or rotating parts, block solid foreign entry, and avoid adverse effects from water and oil ingress. The protection forms are codified as follows:

Efficient Cooling Method
The WE series utilizes F-class insulation, with temperature rise evaluated under B-class standards. For demanding environments, nano-insulating impregnation resin is available to significantly enhance the motor's longevity and performance.
To ensure unparalleled reliability, the motor incorporates high-quality insulating materials between live components and the casing. The life span of these insulators is intrinsically linked to their grade and operating temperature. As a dynamic component, the motor inevitably experiences energy losses during operation, leading to temperature increases. However, the insulation grade, maximum service temperature, and resistance-measured temperature rise are strictly regulated by the following table to guarantee optimal performance within safe temperature parameters.

Bearings, being critical wear components, require regular maintenance and timely grease replacement to maximize their lifespan. Failure to promptly replace damaged bearings can lead to motor burnout. Designed to last, the motor's bearings boast a service life of at least 20,000 hours for 2-pole motors, and an impressive 30,000 hours for 4-pole and 6-pole motors, assuming regular maintenance under normal 50Hz operational conditions.
