Product Description

YVF2 series variable frequency speed regulation three-phase AC motor adopts special design technology and belongs to an AC speed regulating motor powered by inverter power supply. The series of motors and inverters form a mechatronic system that can operate at constant torque and constant power over a wide range.
YVF2 series variable frequency speed control AC asynchronous motor has wide speed regulation range, low vibration and low noise. The motor adopts a squirrel-cage structure, which is reliable in operation and easy to maintain. The variable frequency speed control AC motor is equipped with an independent fan system to ensure that the motor has good cooling effect at different speeds. This series of motors outputs constant torque when operating in the 3-50Hz frequency range and constant power when operating at 50-100Hz.

(1) High efficiency and remarkable energy saving;
(2) Speed regulation smoothing can stepless speed regulation in the range of 5-100HZ.
(3) When the low frequency starts, the torque is less affected by the load;
(4) The starting current is small, no additional starting equipment is required;
(5) Small in size, light in weight, and the same size as the Y series;
(6) An axial fan is installed in the hood, which has good cooling effect at various speeds;
(7) Wide application range, constant torque operation below 50HZ, constant power operation above 50HZ;
(8) Compared with the electromagnetic speed regulating motor, the structure is simple, the use is reliable, and the maintenance is convenient.


Main process flow of the motor
Motor stator: casing processing → punching press → iron core seating → coil making → weaving → dipping paint drying
Electronic rotor: blank shaft processing → iron core press installation → iron core cast aluminum → rotor string shaft → weave → dipping paint drying → dynamic balance
Motor assembly: stator rotor assembly → machine test → motor appearance coloring → packaging storage
