I. Overview of YVFE3 series ultra-efficient variable frequency speed regulating motor:

YVFE2/E3 series variable frequency speed regulation three-phase asynchronous motor is a new generation of variable frequency speed regulating motor developed on the basis of introducing foreign advanced technology and summarizing the experience of YJT series variable frequency speed regulating motor produced by our factory for many years.

In terms of electromagnetic design, the stator, rotor slot and winding form, connection method, etc. are adjusted to adapt to the power supply of the inverter, and it can not only ensure the overload capability of the motor at high frequencies, but also Maintain constant torque output at low frequencies. In terms of structural design, the installation size is the same as that of the Y series motor. Except for the small length, the other dimensions are the same as those of the Y series motor, and the interchangeability is strong, which is convenient for users to use. This series of motors adopts independent axial flow fan forced ventilation to ensure that the motor has good cooling effect in the whole frequency range, and the temperature rise does not exceed the specified value.

Compared with other speed control methods, YVFE2/E3 series variable frequency speed regulation three-phase asynchronous motor and frequency conversion device have remarkable energy saving effect, good speed regulation performance, wide speed regulation range, low noise and small vibration. With the characteristics of various inverters at home and abroad, it can be widely used in the fields of constant torque and constant power speed regulation in light industry, textile, chemical, metallurgy, machine tools and other industries, as well as energy-saving speed regulation of fans and pumps. To achieve automatic control of the speed control system.

The 4-pole motor of YVFE2/E3 series motor complies with the requirements of JB/T7118-93 of "Small-scale variable-voltage variable-speed speed-regulating motor and power supply technical conditions". Other pole motors comply with IEC34-1 and also comply with GB/T755. .

Second, YVFE3 series ultra-efficient variable frequency speed control motor model description

Take YVFE2/E3-200L1-6 as an example: YVFE2/E3 represents the motor model; 200 represents the center height (mm); L represents the frame length code; 1 represents the core length code; 6 represents the motor pole number.
