The WE series motors are engineered with a standard protection grade of IP55, offering excellent defense against environmental factors. For tailored protection, these motors can be customized to IP56, IP65, IP66, and beyond, based on specific customer needs.
The protective shield of the WE series is meticulously designed to prevent electric shock, intrusion of solid foreign objects, and the detrimental effects of water and oil ingress. Detailed below are the protection codes and their defined meanings:
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 employs advanced F-class insulation, with temperature rise evaluated under B-class standards. For enhanced durability in challenging power supply and operational environments, nano-insulating impregnation resin is an available option, significantly prolonging motor life.
Reliable operation of the motor is ensured through superior insulating materials that separate live components either from the casing or from each other. The durability of these materials is intrinsically linked to their insulation grade and thermal performance. As an integral element for energy or signal conversion, the motor experiences natural energy loss, which results in rising temperatures. Nevertheless, the motor's insulation grade, maximum service temperature, and permissible temperature rise assessed through resistance methods meet the stringent criteria outlined below. Within these parameters, the motor is designed to perform optimally.
Insulation grade | Limited temperature°C | The temperature rise limit K |
