Electric motors 4 kW

Description

We have been producing industrial equipment for more than 15 years, and during this time we have identified a priority goal: to produce asynchronous motors of the AIR series, in particular, electric motors with a capacity of 4 kW.

Features of 4 kW AIR electric motors

One of the representatives of this series is the 4 kW electric motor. It is used in alternating current networks with a frequency of 50 Hz. In this case, the rated power should be 220, 380 or 660 V. The maximum deviation from the passport data is 5%. Variations of this model are represented by models with different heights of the shaft axis. It can be 100, 112 or 132 mm. In this case, the length of the shaft varies from 60 to 80 mm.

Depending on the number of poles on the stator, the rotor speed of the electric motor changes.

Motor rotor speed (rpm)

  • 3000 rpm;
  • 1500 rpm;
  • 1000 rpm;
  • 750 rpm

Degrees of protection of AIR electric motors

Like other models of the AIR series, 4 kW electric motors have an IP54 degree of protection, which prevents the negative impact of dust and splashes of water on the working elements of the product. At the same time, when the product is in operation, there should be no conductive particles or aggressive vapors /gases in the air that react with the metal.

The permissible temperature range is -40 .. + 40 ° С. With high humidity, the upper threshold drops to + 25 ° C. The 4 kW electric motor must be located at an altitude of 1000 m above sea level.

Subject to the operating instructions, the warranty period for 4 kW electric motors is 24 months from the date of purchase.
