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


Model Explanation



西安泰富西瑪電機:YVFE3系列超高效變頻調速三相異步電動機型號說明


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.

Motor Structure

  1. The enclosure protection level is IP55, and it can also be made into IP55 according to user requirements.
  2. The cooling method is full - enclosed cooling with an axial flow fan (IC416).
  3. According to user requirements, various high - resolution sensors (photoelectric encoders, resolvers, and tachogenerators) can be equipped.
  4. According to user requirements, electromagnetic braking devices (both power - on and power - off braking are available), gear reducers, and other accessories can be equipped.
  5. When viewed from the shaft extension end, the motor junction box is located on the right side of the frame. It can also be located on the left side or at the top of the frame according to user requirements.

Main Technical Performance and Technical Parameters of the Motor

  1. The motor operates in continuous duty.
  2. The rated voltage is 380V, and the rated frequency is 50HZ. The voltage and frequency at the rated point can also be determined according to user requirements.
  3. The insulation class is F.
  4. For center heights of H80 - 255, 5 - 50HZ is for constant - torque speed regulation; for center heights of H250 - 355, 3 - 50HZ is for constant - torque speed regulation, and 50 - 100HZ is for constant - power speed regulation. The high - frequency range can also be determined according to user requirements.
  5. It has a strong overload capacity.
  6. It has good low - speed performance.
  7. The frame numbers of 280 and below use the Y connection method, and 315 - 355 use the △ connection method.

Operating Conditions of Variable - Frequency Motors

  1. The altitude does not exceed 1000m.
  2. The ambient air temperature varies with the season, but does not exceed 40℃, and the minimum does not exceed - 15℃.
  3. The average relative humidity of the wettest month is 90%, and the average minimum temperature of that month is not higher than 25℃.

Ordering Notes for Xi'an Simo Variable - Frequency Motors

  1. Please indicate the motor model, power, speed regulation, voltage, frequency, noise, and installation type when placing an order. If the noise level is not specified, it will be supplied as level 2.
  2. If there are special requirements, please indicate them in the contract and contact the manufacturer in advance.
