Low voltage high power squirrel cage motor

The low-voltage variable frequency motor has the characteristics of wide speed regulation range, low vibration and low noise. The motor adopts the squirrel-cage structure, which is reliable in operation and convenient in maintenance. The installation dimensions and power levels are in accordance with the IEC standard, which is consistent with the corresponding Y series low-voltage motors. Interchangeability and versatility.

The low-voltage variable frequency speed control motor is equipped with an independent cooling fan to ensure that the motor has good cooling effect at different speeds. This series of motors outputs constant torque when operating from 5 (3) to 50 Hz, and outputs constant power when operating from 50 to 100 Hz.

The low-voltage variable frequency motor can be used with many inverters, and controlled by the inverter to achieve the speed under different conditions.

(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
