Electric motors 55 kW

Description

Asynchronous general industrial motors AIR are a number of models that are connected by the regularity of dimensions and technical parameters. They are unified and meet the RS3031-71 standard with their dimensions. LLC “Dneproresurs”, engaged in the production of this line, has been producing industrial electrical equipment since 1998. Asynchronous electric motors have a number of positive qualities, such as reliability during overloads, high efficiency, low reactive currents, and ease of starting.

Medium Power Motors Features

The 55 kW electric motor is a representative of the AIR line of medium power. It uses AC mains as its power source. Its required parameters: frequency 50 Hz, rated power 220/380 or 380 / 660V, depending on whether “delta” or “star” is used as the connection diagram. The frequency of rotation of its rotor depends on the number of pole pairs on the winding of its stator:

  • 1 pair of poles – 3000 rpm;
  • 2 pairs – 1500 rpm;
  • 3 pairs – 1000 rpm;
  • 4 pairs – 750 rpm.

Along with this, the dimensions of the 55 kW electric motor also change. The length of the shaft, depending on these parameters, is 110, 140, 140, 170 mm, and the height of its axis is 225, 225, 250, 280 mm, respectively. More detailed information about the dimensions of 55 kW electric motors, as well as their weight and other technical parameters can be found in the section “Tech. characteristics of AIR “.

Rules for the use of 55 kW electric motors

AIR series motors must be located in rooms where the temperature is maintained between -40 .. + 40 ° C. Dust content should not exceed 10 mg / cubic meter. m. The air must be free of conductive particles, corrosive or explosive gases / vapors. The degree of protection IP54 protects the product from moisture droplets.

All 55 kW electric motors have a 2 year warranty.
