An electric motor is an electrical machine that is designed to convert the energy of an electromagnetic field into mechanical work. Such a device can be used to ensure the functioning of machines, escalators, compressor units, pumps, ventilation equipment, etc. In order to choose the most optimal electronic engine AIR, you need to go to the site , which contains complete information about all currently produced models.
Electric motors for general use
The induction motor was first developed in 1949. At that time, two series of such units were produced - A and AO, which were popular for more than ten years. In 1961, a unified series of A2 and AO2 models was released into mass production.
In the 70s of the last century, devices 4А and 4АН entered production, the technical and economic indicators of which fully corresponded to the world level of technology development. After some time, a modernization process took place, which made it possible to achieve such changes as:
- noise reduction;
- weight reduction;
- performance improvements.
Motor Specifications
The AIR electric motor is an asynchronous device with a squirrel-cage rotor. Structurally, this device is quite simple, which significantly increases the degree of its maintainability. This is facilitated, among other things, by the complete absence of mobile contacts. In this regard, the cost of this equipment is also insignificant.
The degree of motor protection according to GOST 17494-87 reaches IP54 and IP55, depending on the model. Insulation class of heat resistance of all types of devices - "F" in accordance with GOST 8895-93.
The manufacturer has provided a cooling method 1C-0151. The motors use the S1 operating mode. At the same time, models with a climatic version of the U2 and U3 types are available on the market. All engines have a class 2 noise level at idle.
The power of the motors varies from 0.18 to 132 kW. They are capable of developing from 750 to 300 rpm. The efficiency of such devices can reach 95.4%.
