YJTG/YVF series variable frequency speed regulation three-phase asynchronous motorDetailed product description：

The YJTG series variable frequency speed regulating three-phase asynchronous motor is a new generation of variable frequency speed regulating motor developed to meet market demand, based on the introduction of advanced foreign technology and the summary of our factory's years of experience in producing YJT series variable frequency speed regulating motors. In terms of electromagnetic design, adjustments have been made to the slot shapes, winding types, and connections of the stator and rotor to adapt to the power supply of the frequency converter. This ensures that the motor has overload capacity at high frequencies and maintains constant torque output at low frequencies. In terms of structural design, the installation dimensions are the same as those of the Y series motor. Except for the length dimension, other external dimensions are also the same as those of the Y series motor, with strong interchangeability and easy compatibility for users to use. This series of motors adopts independent axial flow fans for forced ventilation, ensuring that the motor has good cooling effect throughout the entire frequency range and the temperature rise does not exceed the specified value.

The speed regulation system composed of YJTG series variable frequency speed regulation three-phase asynchronous motor and variable frequency device has significant energy-saving effect, good speed regulation performance, wide speed regulation range, low noise and small vibration, and can be matched with various frequency converters at home and abroad compared with other speed regulation methods. It can be widely used in constant torque and constant power speed regulation occasions in industries such as light industry, textile, chemical industry, metallurgy, machine tools, as well as energy-saving speed regulation of fans, water pumps, etc., which helps to achieve automatic control of the speed regulation system.

The 4-pole motor of YJTG series motor complies with the provisions of JB/T7118-93 "Technical Conditions for Small Variable Frequency and Variable Voltage Speed Control Motors and Power Supply", and the motors with other pole numbers comply with the provisions of IEC34-1 and GB/T755.
