The WE series comes standard with an impressive protection grade of IP55, with possibilities for customization to IP56, IP65, IP66, and beyond, tailored to meet specific customer requirements.
The protection level of the shell is meticulously designed to shield against electrical shocks, prevent contact with live or rotating parts within the shell, block solid foreign objects, and guard against the detrimental effects of water and oil ingress. The protection forms are translated into codes with specific meanings as follows:
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
Designed with precision, the WE series employs F-class insulation, while temperature rise is evaluated based on B-class standards. To extend durability in complex environmental conditions, a nano-insulating impregnation resin is available as an upgrade, enhancing longevity in diverse power supply and usage environments.
For reliable operation, insulating materials separate live parts from the shell and each other. The lifespan of these materials is intricately linked to their insulation grade and the operating temperature. As an energy or signal conversion element, the motor experiences energy loss during operation, leading to temperature rise. Typically, the insulation grade, maximum service limit temperature, and resistance-measured temperature rise limit conform to the following table. Within these limits, the motor functions flawlessly.
Insulation grade | Limited temperature°C | The temperature rise limit K |
B | 130 | 80 |
F | 155 | 105 |
