. Noise levels
Noise levels are well below those specified in EN 60034-9, ensuring a quieter operational experience. Noise measurements are performed according to EN ISO 1680 and EN 21680 according to class 2 in an state-of-the-art anechoic room, ensuring precision and accuracy. The sound pressure level "Lp" and the sound power level "Lw" in dB(A) are indicated for the individual frame sizes in the comprehensive operating datasheets, making data accessible and clear. 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, offering flexibility and reliability: +3dB(A).
. Vibration levels
Vibration limit (IEC60034-14)
 Note: Grade "A" is applicable to motors with no special requirements on vibration. It is the default configuration. Grade "B" for motors with special vibration requirements

Bearing type
 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.

Lubrication

Maintenance free - sealed for life bearings
 Relubrication intervals for horizontal construction type:
 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 depicted in the installation size code E size). The radial force length X (mm) isthe 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 axialextension (size value E). Maximum allowable radial force, as seen in the table below. Bearing life For


standard ball
bearings, under the action of allowable load, the bearing design life of the motor can meet the required standards. Essential performance criteria include the following: ensuring compliance with the following requirements: at least a remarkable 20000 operational hours for the 2-pole motor variant. The motor with 4 poles, and the 6 pole motor model should perform for at least an impressive 30000 continuous hours of service. (This standard refers to the motor's expected life span under consistent normal operation conditions at 50Hz and accompanied by routine maintenance as required).
