Take YVFE2 - 132S2 - 2 as an example: YVFE2 is the motor model. YVF indicates variable - frequency speed regulation, and E2 represents IE2 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.

Xi'an Simo YVFE2 series high - efficiency variable - frequency speed - regulating three - phase asynchronous motors are a new generation of variable - frequency speed - regulating three - phase asynchronous motors developed to meet market needs. They are developed on the basis of introducing foreign advanced technologies and summarizing the factory's many years of experience in producing YJTG series variable - frequency speed - regulating three - phase asynchronous motors.
In terms of electromagnetic design, the stator and rotor slot shapes, winding forms, and connection methods have been adjusted to adapt to the power supply of the frequency converter. Moreover, it can not only ensure the overload capacity of the motor at high frequencies but also maintain a constant torque output at low frequencies. In terms of structural design, the mounting dimensions are the same as those of the Y - series motors. Except for a slightly smaller length dimension, other external dimensions are also the same as those of the Y - series motors, with strong interchangeability, which is convenient for users to match. This series of motors uses an independent axial - flow fan for forced ventilation to ensure that the motor has a good cooling effect within the entire frequency range and the temperature rise does not exceed the specified value.
The speed - regulating system composed of the YVFE2 high - efficiency variable - frequency speed - regulating three - phase asynchronous motor 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 applied to constant - torque and constant - power speed - regulating occasions in industries such as light industry, textiles, chemicals, metallurgy, and machine tools, as well as energy - saving speed regulation of fans, water pumps, etc., helping to realize the automatic control of the speed - regulating system.
The 4 - pole motors of this series comply with the provisions of "Technical Conditions for Small - sized Variable - Frequency and Variable - Voltage Speed - regulating Three - phase Asynchronous Motors and Power Supplies" JB/T7118 - 93. The motors of other pole numbers comply with the provisions of IEC34 - 1 and also with GB/T755.
