YVFE3 High-Efficiency Variable Frequency Three-Phase Asynchronous Motor

Xi’an TaiFu Simo Motors: YVFE3 Series Ultra-High-Efficiency Variable-Frequency Speed-Regulating Three-Phase Asynchronous Motor

Model Explanation

      Taking the YVFE3-132S2-2 as an example: YVFE3—Motor model, YVF indicates variable-frequency speed regulation, E3 represents IE3 ultra-high efficiency; 132—Center height; S—Frame length code; 2—Core length code; 2—Number of poles.

Motor Overview

The Xi’an TaiFu Simo YVFE3 series ultra-high-efficiency variable-frequency speed-regulating three-phase asynchronous motor is derived from the YE3 series motor, achieving an efficiency standard of IE3. Structurally, the heat dissipation fins are arranged in a parallel and vertical distribution, offering a novel design and unique appearance. The terminal box is located on the top of the motor, making wiring more convenient for users. Components such as the frame and end cover are designed for reduced noise and vibration. An axial fan is used for forced ventilation, ensuring that the motor’s temperature rise does not exceed the specified value during long-term constant torque operation at low speeds. The design fully considers the adverse effects of inverter power supply on the motor, ensuring strong overload capacity at high frequencies and maintaining constant torque output at low frequencies.

The YVFE3-80-160 models are equipped with fully enclosed, maintenance-free bearings, while the YVFE3-180-355 models feature front and rear bearings with oiling devices for easy maintenance.

This series of ultra-high-efficiency variable-frequency speed-regulating three-phase asynchronous motors, combined with a variable-frequency device, offers significant energy-saving effects, excellent speed regulation performance, a wide range of speed adjustments, and features such as low noise and minimal vibration. They can be paired with various domestic and international frequency converters and are widely used in industries such as light manufacturing, textiles, chemicals, metallurgy, and machine tools, especially in applications requiring constant torque and constant power speed regulation, as well as in energy-saving speed regulation for fans and pumps, contributing to the automation control of the speed regulation system.

The 4-pole motors in this series comply with the JB/T7118-2004 standard, while other pole numbers comply with IEC34-1 and GB755 standards.

Motor Structure

1. The enclosure protection level is IP55, but it can also be customized to IP55 according to user requirements.
2. The cooling method is fully enclosed with an axial fan (IC416).
3. High-resolution sensors (such as photoelectric encoders, rotary transformers, and tachogenerators) can be added upon user request.
4. Electromagnetic brakes (both power-on and power-off types), gear reducers, and other accessories can be added as per user requirements.
5. Viewed from the shaft extension end, the motor terminal box is located on the right side of the frame but can be positioned on the left side or top based on user requirements.
