Electric motor AIR 90
Description
Electric motors AIR 90 series, with a squirrel-cage rotor, belong to asynchronous motors, manufactured for operation in an alternating current network with a voltage of 380V (three) or 220 / 380V (six terminals). AIR 90 electric motors are produced in climatic version U3 or U2 – for operation under a canopy or in a closed room.

Scope of AIR 90 electric motors
The main condition for the operation of the electric motor is protection from direct exposure to sunlight and precipitation. P54 enclosure protection guarantees protection against dust and splash water.
The AIR 90 electric motor can be manufactured in a gray cast iron or silumin casing.
Electric motors AIR 90 have various mounting options – with feet, with a flange, and a combined version.
Asynchronous three-phase electric motors AIR 90 are used in all industrial areas, in particular, they are installed on electric drives of various industrial machines, heavy mechanisms.

Advantages of AIR 90 engines
The AIR 90 electric motor has a number of significant advantages, in particular, it perfectly withstands short-term mechanical overloads.
Also, the AIR 90 electric motor has a simple and reliable design. The ribbed body, made of gray cast iron or silumin, has special ribs that improve cooling.
The AIR 90 electric motor is distinguished by ease of start-up and easy automation, constant speed at different loads.
The increased multiplicity of starting torques has increased the operational reliability during starts.
The level of efficiency of the engine reaches 81%, which became possible due to the accuracy of its execution.
The noise level is significantly reduced (55 dB), since high-precision bearings are used in the design. The enclosure’s IP54 degree of protection guarantees protection against dust and splash water.
The level of reactive currents is reduced to 0.86, which helps to reduce the risk of overvoltage in the network.
