Ingress protection
The standard WE series provides IP55 protection, with options for customization to IP56, IP65, IP66, and beyond, tailored specifically to meet customer requirements.
The protection level is crucial to guard against electric shocks, ensure safe distances from live or moving parts, and block foreign solids. It also prevents damage from water and oil ingress. The following codes define the varied protection forms available:

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

Boasting F-class insulation, the WE series is evaluated based on a B-class temperature rise. For enhanced longevity in demanding environments, nano-insulating impregnation resin is an available option.
To ensure reliable operation, motors are insulated to separate live components from each other and the casing. The lifespan of this insulation is tightly linked to its class and the operating temperature. Energy conversion during motor operation intrinsically causes heat buildup. Under standard conditions, the insulation grade, maximum allowable temperature, and resistance method-assessed temperature rise meet the table's criteria, ensuring smooth motor performance within these limits.

Bearings, as critical wear components in motors, require consistent maintenance and timely grease replacement to maximize their lifespan. Neglecting damaged bearings may lead to motor burnout. For loads within permissible limits, motor bearings are designed to last: a minimum of 20,000 hours for 2-pole motors and at least 30,000 hours for 4-pole and 6-pole motors, assuming normal operation at 50Hz and adherence to maintenance protocols.
