Electric motors 75 kW

Description

Among asynchronous motors, models included in the AIR series are in special demand. This is a line of unified engines for Interelectro that meets the RS3031-71 standard. It is produced by Dneproresurs LLC, which has been manufacturing industrial equipment for more than 15 years. The popularity of this series is due to its quality, ease of setup, use, maintenance and high efficiency factor.

Parameters of 75 kW electric motors

Electric motor 75 kW is one of the representatives of the AIR line. Like its other models, they are demanding on the power supply. It should be an AC power grid with a frequency of 50 Hz and a rated voltage of 220/380 or 380 / 660V. The indicated values ​​should not fluctuate by more than 5%. A larger deviation can cause unstable operation of the product and, as a result, its failure. Electric motor 75 kW has the only modification at release – a general industrial motor. Any adjustments, such as an electromagnetic brake or thermal sensors, must be agreed with the manufacturer in advance.

The engine has 4 variations:

  • 2 poles on the stator winding, 3000 rotor revolutions per minute;
  • 4 poles, 1500 rpm;
  • 6 poles, 1000 rpm;
  • 8 poles, 750 rpm

The dimensions of the motor shaft are also associated with these parameters. Its diameter varies from 70 to 80 mm, the height of the axis is from 250 to 280 mm, and the length is from 140 to 170 mm. More detailed information about this series and about each of its representatives separately – on our website, in the section “Tech. characteristics of AIR “.

Electric motors 75 kW must be located in rooms with a temperature of -40 ° C .. + 40 ° C. The maximum allowable dust content is 10 mg / m3. m. The air must not contain conductive particles or aggressive vapors / gases.

Any 75 kW electric motor is covered by a 2-year warranty from the date of purchase.
