YVFE3 High-efficiency Variable-frequency Three-phase Asynchronous Motor

Xi'an Simo Motor: YVFE3 Series Ultra-high Efficiency Variable-frequency Speed-regulating Three-phase Asynchronous Motors

Model Explanation

Take YVFE3 - 132S2 - 2 as an example: YVFE3 is the motor model. YVF indicates variable - frequency speed regulation, and E3 represents IE3 ultra - high efficiency; 132 is the center height; S is the frame length code; 2 is the core length code; 2 is the number of motor poles.

Motor Overview

Xi'an Simo YVFE3 series ultra - high efficiency variable - frequency speed - regulating three - phase asynchronous motors are variable - frequency motors derived from the YE3 series motors, and their efficiency reaches the ultra - efficiency standard of IE3. In terms of structure, its heat sinks are distributed in parallel and vertical forms, with a novel structure and a unique appearance. The junction box is located on the top of the motor, which is convenient for users to connect wires. The design of components such as the frame and end covers is reasonable, making the overall machine have lower noise and less vibration. Axial flow fans are used for forced ventilation to ensure that the temperature rise of the motor does not exceed the specified value when it runs at low - speed constant torque for a long time. The adverse effects of the power supply of the frequency converter on the motor design are fully considered, ensuring the overload capacity of the motor at high frequencies and maintaining a constant torque output at low frequencies.
YVFE3 - 80 - 160 adopts fully - enclosed maintenance - free bearings, and YVFE3 - 180 - 355 has oil injection devices on the front and rear bearings, which is convenient for maintenance.
The speed - regulating system composed of this series of ultra - high efficiency variable - frequency speed - regulating three - phase asynchronous motors and the frequency - conversion device, compared with other speed - regulating methods, has significant energy - saving effects, good speed - regulating performance, a wide speed - regulating range, low noise, small vibration, and can be matched with various domestic and foreign frequency converters. It can be widely used in industries such as light industry, textiles, chemicals, metallurgy, and machine tools for constant - torque and constant - power speed - regulating occasions, as well as for energy - saving speed regulation of fans and water pumps, helping to realize the automatic control of the speed - regulating system.
The 4 - pole motors of this series comply with the regulations of JB/T7118 - 2004, and the motors of other pole numbers comply with the regulations of IEC34 - 1 and also with GB755.
