   Ingress protection

WEX3 standard ingress protection is IP55. Depending on customer requirements, this range can be supplied with IP56, IP65 or IP66 ingress protection.
The protection level of the shell is mainly to prevent electric shock to human body or close to live parts or rotating parts, to prevent solid foreign matter from entering and to prevent harmful effects caused by water and oil,  The code name and meaning of the protection form is shown in the table below.

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 cooling methods for electrical machines are stated in code according to IEC 60034-6. The code consists of the letters IC (International Cooling) and a three-digit number.
The standard featured in this list are classified in the cooling method IC 411 (surface-cooled) IC410 and IC416 cooling modes can be provided for special needs of users.

WEX3 standard Insulation grade is F grade insulation, and the temperature rise limit is assessed as B grade (Δ80K), to further improve the service life in the power supply environment and service environment.Depending on customer requirements, this range can be supplied H grade insulation.

.   Noise levels
Noise levels are well below those specified in EN 60034-9. Noise measurements are performed according to EN ISO 1680 and EN 21680 according to class 2 in an anechoic room. The sound pressure level "Lp" and the sound power level "Lw" in dB(A) are indicated for the individual frame sizes in the operating datasheets. They apply for rated loads at 50 Hz, plus a tolerance of +3 dB(A). They apply for rated loads at 60Hz , 2P plus a tolerance of  +5dB(A), and 4P or above: +3dB(A).

Note:  1. The standard configuration is deep groove ball bearing: H80~280 are sealed and maintainable, H315~355 are relubricated bearings;
2. Optional 1: Re-lubricated bearing, suitable for H160~280 motors
3. Optional 2: Angular contact ball bearing, which is mostly suitable for vertical installation of V1 and can bear larger axial load;
4. Optional 3: Cylindrical roller bearing, which is mostly suitable for horizontal motor installation and can bear larger radial load. .   Bearing location
Motor standard design:
H80-H132 Non-drive end designed  as the located bearing. H160-H355 Drive end designed  as the located bearing.

Mounting type	Frame sizes	Poles	RT≤40°C
B3, B5, B35	80 to 280	2P	20000h
		4P	40000h

Relubrication intervals for horizontal construction type:
 

Mounting type	Frame sizes	Poles	Lubrication interval(h)			Grease quantity (g)
			40°C	50°C	60°C
B3, B5, B35	160 to 355	2P	2500	1000	500	30
		4P	5000	2500	2000	40

Note: 1. The table data is applicable to 50Hz motor. For 60Hz motor, the time interval should be multiplied by 0.8;
2. For vertical motor installation, the lubrication interval shall be divided by 2;
3. Re-greasing intervals should be halved for every 15°C rise above 70°C. .   Permissible forces at the shaft end
Maximum radial force (for pulley drive system): The maximum allowable radial force F0(unit: N) for radial load is based on the premise that the load line (center of pulley) must be within the length of the motor shaft extension (the motor shaft elongation is shown in the installation size code E size). The radial force length X (mm) is the distance from the axial extension shoulder to the radial force F0 action line, so when the length X= Max, it is the total length of the axial extension (size value E). Maximum allowable radial force as below table.


.   Bearing life
For standard ball bearings, under the action of allowable load, the bearing design life of the motor can meet the following requirements: at least 20000 hours for the 2-pole motor, 4 poles, 6 pole motor at least 30000 hours (refers to the motor life under normal operation at 50Hz and normal maintenance as required).
