Features of AIR 71 electric motors
The AIR 71 B2 electric motor operates at a rated speed of 3000 rpm. The AIR 71 electric motor is equipped with a squirrel-cage rotor, designed for use in a network with an alternating current frequency of 50 Hz, at a voltage value of 220, 380 V.
The AIR 71 electric motors differ in the shaft rotation height of 71 mm, the shaft diameter of 19 mm, and the power of 0.75 kW. The climatic version corresponds to the U3 marking.
The engine body is made of silumin alloy, the degree of protection corresponds to the IP 54 marking, which means that the engine is protected from dust and splashing water.
Electric motors AIR 71 v2 are available in various mounting options: on feet, with a flange, combined (feet in combination with a flange).
Scope of AIR 71 electric motors
AIR 71 electric motors are designed for use in various industries, and their versions provide the necessary versatility. So, the AIR 71 electric motor can be produced in the basic version, in a modification for various environmental conditions (tropical, agriculture, chemically resistant). Also, the AIR 71 electric motor differs in dimensional accuracy for installation – high and increased accuracy.
Electric motors can also be equipped with additional devices, for example, an electromagnetic brake.
Some modifications of electric motors are produced with increased slip characteristics. There are also highly specialized options for electric motors, for example, for use on ships, for driving monoblock pumps.
