Asynchronous engines of general-industrial purpose A2 and AO2 are designed for a long mode of operation on a three-phase alternating current network.
Nominal characteristics (power, current, voltage, number of revolutions, utility coefficient) belong to the nominal values of the climatic factors of the environment and the minimum ambient temperature values: -40 ° C during operation and -45 ° C during storage.
Electric motors of all dimensions are made with six output ends. The circuit of the windings is “triangle”, “star” and a triangle /star at the request of the customer.
Engines have similar ones that are currently produced by a series of AIR by the degree of protection against environmental exposure:
- Closed execution (IP44) (IP54) from cast iron (AO2) - from 3 to 9 dimensions;
- Closed execution (IP44) (IP54) from aluminum alloys (AOL2) - from 1 to 3 dimensions.
The structure of designation of the electric motor consists of marking the execution by the degree of protection (AO2, AOL2), designation of the type of electric motor (the first digit indicates the serial number of the overall size, the second - marking the length of the core), the number of poles, climatic execution and the placement category.
An example of a symbol of the symbol:
AO2-62-4U3-electric motor of a closed blowing performance with a bed and shields of cast iron, 6th dimensions, 2nd core length, four-pole (1,500 rpm), climatic execution U, category of accommodation 3.
Structural scheme for the designation of engines
1-name of the product;
2-labeling of the AO2 series, AOL2
3-the first digit of the dimensions, the second digit is the conditional length of the stator core;
4-F-independent ventilation, 2P-frequency regulation, with high sliding.
5-the number of poles (2; 4; 6; 8; 10; 12);
6-B-temperature protection,
7-designation of the climatic execution of the engine according to GOST 15150 (y; m; m; TV);
8 - designation of the category of engine placement according to GOST 15150 (3; 4);
An example of recording the designation of the AO2-32-4U3 engine with a voltage of 220/380V, the network frequency of 50Hz, 3KW, execution IM1081 with the introductory device K-3-1:
1. For intra-Russian deliveries:
Engine AO2-32-4U3, 220/380V, 50Hz, IM1081, K-3-1, 3N
