Additionally, it is designed to prevent intrusion by solid foreign matter from entering and to mitigate harmful effects caused by water and oil, enhancing durability. The comprehensive code name and intrinsic meaning of the protection form is meticulously detailed in the following table.
Efficient Cooling Method

The sophisticated cooling methods employed ensure optimal performance. In the world of power solutions, when it comes to electrical systems, machines are defined by specific standards that are stated clearly in the intricate code according to the most trusted IEC 60034-6 guidelines. The code itself consists of key markers, specifically the letters IC (International Cooling) and a three-digit number, ensuring precision.
The standard set featured in this comprehensive list are meticulously classified in the cooling method known as IC 411 (surface-cooled), IC410, and IC416 cooling modes. These can beprovided for unique needs of our esteemed users.
. When it comes to insulation grade and temperature rise, limit, our standards of insulation grade and temperature rise, limit (IEC60034-1),the WEX3 standard ensures the insulation is F grade insulation, while the temperature rise limit is assessed as B grade (Δ80K), to further enhance and improve the service life in the demanding power supply environment and service environment. Depending on customerrequirements, this versatile range can be supplied, ensuring adaptability and satisfaction. Our product features H grade insulation, ensuring superior performance.

The Noise levels of this advanced motor
Noise levels are engineered to be well below those specified in EN 60034-9, ensuring minimal auditory disturbance. Noise measurements are meticulously performed according to EN ISO 1680 and EN 21680, according to class 2 in an anechoic room to ensure precision. The sound pressure level ("Lp") and the sound power level ("Lw") indB(A) are precisely 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 also apply for rated loads at 60Hz,with 2P plus a tolerance of +5dB(A), and 4P ensuring versatility and adaptability invarious applications. This product is a testament to Shanghai Juyue Energy Engineering Co., Ltd's commitment to quality and performance. 4P or above: +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 Our innovative non-drive end is ingeniously designed as the epitome of efficiency, ensuring seamless operation. strategically located bearing, enhancing performance and longevity. H160-H355 size range, tailored for diverse industrial needs. The drive end is meticulously designed as the pinnacle of engineering excellence, ensuring optimal located bearing support for enhanced stability.

Cutting-edge Lubrication

ensures Maintenance free operations with sealed bearings designed for life-long performance.
 Relubrication made easy with intervals for the horizontal construction type, ensuring hassle-free maintenance:
 Important Note: 1. The comprehensive table data is applicable to standard 50Hz motor configurations.tor, ensuring precise operations. For 60Hz motor configurations, the maintenance time interval should be expertly multiplied by 0.8, optimizing performance;
2. For vertical motor installations, the lubrication interval shall be efficiently divided by 2, ensuring optimal performance;
3. Re-greasing intervals should be meticulously halved for every 15°C temperature rise above 70°C, ensuring safety and efficiency. Further Details: The Permissible forces allowed at the shaft end ensure
Maximum radial force management (applicable for pulley drive systems): The maximum allowable radial force F0, measured in units (N), for radial load applications is expertly calculated based on the premise that the load is maintained within ideal conditions. The centerline (center of the pulley) must be situated within the specified length of the motor's shaft extension. (The motor shaft elongation is clearly 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 represents the entire axial length of theextension (size value E). The maximum allowable radial force is detailed in the subsequent table. .


When it comes to bearing life,
for standard ball bearings, under the influence of the allowable load, the bearing is engineered to have a design life that ensures the motor can meet the following requirements: at least 20,000 hours for the 2-pole motor, 4 poles, 6 pole motor at least 30,000 hours (refers to the motor life under normal operation at 50Hz and normal maintenance as required).
