Motor Overview

The Xi’an TaiFu Simo YVFE2 series high-efficiency variable-frequency speed-regulating three-phase asynchronous motor is a new generation of variable-frequency speed-regulating motor, developed to meet market demands by introducing advanced foreign technology and building on the experience of producing the YJTG series variable-frequency speed-regulating three-phase asynchronous motors.

In terms of electromagnetic design, adjustments have been made to the stator and rotor slot shapes, winding forms, and connection methods to adapt to the conditions of inverter power supply. This design ensures that the motor can maintain strong overload capacity at high frequencies while also sustaining constant torque output at low frequencies. Structurally, the installation dimensions are the same as those of the Y series motors, except for smaller length dimensions. Other external dimensions are also consistent with the Y series motors, ensuring strong interchangeability and ease of use for customers. This series of motors uses an independent axial fan for forced ventilation, ensuring good cooling effects across the entire frequency range, with temperature rise not exceeding specified values.

The YVFE2 high-efficiency variable-frequency speed-regulating three-phase asynchronous motor, when paired with a variable-frequency device, offers significant energy-saving effects, excellent speed regulation performance, a wide range of speed adjustments, low noise, and minimal vibration. It can be matched with various frequency converters both domestically and internationally. This motor is widely applicable in industries such as light manufacturing, textiles, chemicals, metallurgy, and machine tools, particularly in scenarios requiring constant torque and constant power speed regulation, as well as in energy-saving speed regulation for fans and pumps, facilitating the automation control of speed regulation systems.

The 4-pole motors in this series comply with the provisions of the “Technical Conditions for Small Variable-Frequency Speed-Regulating Three-Phase Asynchronous Motors and Power Supplies” JB/T7118-93. Motors with other pole numbers comply with IEC34-1 and GB/T755 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.
