Overview

    The YE4 series three-phase asynchronous motor is a highly efficient and energy-saving motor. Its efficiency complies with the Class 2 energy efficiency standard in GB 18613-2020 "Energy Efficiency Limits and Energy Efficiency Grades for Motors", corresponding to the IE4 energy efficiency grade in the International Electrotechnical Commission (IEC) standard.

Basic parameters

• Power: 0.75kW - 355kW
• Number of poles: 2, ​​4, 6, 8 poles
• Voltage: Usually 380V, other voltage options are also available
• Frequency: 50Hz
• Frame size: 80-355
• Protection level: IP55, which can effectively prevent dust from entering and water from splashing into the motor
• Insulation level: F level, with high heat resistance and impact resistance

Performance characteristics

• High efficiency and energy saving: With optimized electromagnetic design, high magnetic silicon steel sheets and low-loss materials, the efficiency is increased by 2% - 3% on average compared with the corresponding specifications of the YE3 series.
• Smooth operation: By optimizing the electromagnetic design and vibration reduction structure, as well as more accurate rotor dynamic balance calibration, the noise and vibration of the motor during operation are effectively reduced, providing a stable and quiet environment for equipment operation.
• High reliability: Using domestic first-line brand bearings, silicon steel sheets and enameled round copper wires, high-strength castings, high-precision bearings and high-temperature resistant insulation materials, with IP55 protection level, it is suitable for harsh working conditions such as dust and humidity, and reduces maintenance frequency.
• Excellent starting performance: With high starting torque, it can quickly start the load, and the starting current is small, which has less impact on the power grid.
• Good heat dissipation performance: The efficient design reduces the heat generated by the motor during operation. Combined with the improved cooling structure, it can effectively delay the aging of the insulation material and extend the life of the motor. It can also operate stably in high temperature or closed environments.

Application areas

    It is suitable for general places and machinery without special requirements, such as metal cutting machine tools, pumps, fans, transportation machinery, mixers, agricultural machinery, food machinery, etc. It is also widely used in manufacturing, mining, chemical, steel, electric power and other industrial fields, providing reliable and efficient power support for various mechanical equipment.

Installation and use

• Installation method: There are multiple installation methods to choose from, including horizontal (B3, B5, B35, etc.) and vertical (V1, V3, V5, etc.), to meet the installation needs of different equipment.
• Environmental requirements: The ambient temperature varies with the seasons, the highest shall not exceed +40℃, the lowest shall not be lower than -15℃ (except for special ambient temperature motors), and the altitude shall not exceed 1000m (except for high altitude motors).
• Transmission mode: Flexible coupling, spur gear and pulley transmission are allowed.
• Starting mode: Direct starting, Y/△ starting, reduced voltage starting, variable frequency starting and other starting modes can be used.
