Motor overview
    Sima YJTG series variable frequency speed regulation three-phase asynchronous motor is a new generation of variable frequency speed regulating motor developed on the basis of adapting to market needs, introducing advanced foreign technology and summarizing the experience of YJT series variable frequency speed regulating motor.
    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 Simma inverter 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.
    YJTG series variable frequency speed regulation three-phase asynchronous motor and variable frequency device constitute the speed control system. Compared with other speed control methods, the energy saving effect is remarkable, the speed regulation performance is good, the speed regulation range is wide, the noise is low, the vibration is small, and it can be compared with domestic The characteristics of various external frequency converters can be widely used in constant torque and constant power speed regulation in light industry, textile, chemical, metallurgy, machine tool and other industries, as well as energy-saving speed regulation of fans and pumps, which is helpful to achieve Automatic control of the speed control system.
    The 4-pole motor of Sima YJTG 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. .
