Asynchronous engines of general industrial assignment types A2 and AO2 are designed for a long mode of operation from a three-phase alternating current network.
Nominal characteristics (power, current, voltage, number of revolutions, coefficient useful action) refer to the nominal values \u200b\u200bof climatic factors external environment and minimum values Environmental temperatures: -40 ° C during operation and -45 ° C during storage.

Electric motors of all dimensions are made with six output ends. Scheme connection of windings - "Triangle", "Star" and a triangle / star at the request of the customer.
Engines have similarities currently produced by the AIR implementation by the degree of protection against environmental protection:

closed version (IP44) (IP54) from cast iron (AO2) - from 3 to 9 envelope;
closed version (IP44) (IP54) from aluminum alloys (AOL2) - from 1 to 3 envelope.

The structure of the motor designation consists of marking the execution according to the degree of protection (AO2, AOL2), the notation of the electric motor type (the first digit indicates the sequence number overall size, the second is - marking the length of the core), the number of poles, climatic execution and the category of placement.
Example of the conditional designation:
AO2-62-4U3 is an electric motor of a closed plotting with a bed and locks from the cast iron, the 6th dimension, the 2nd length of the core, a four-pole (1500 rpm), climatic execution in the category of placement 3.

Structural engine designation scheme

1 - product name;
2 - Marking of the AO2 series, AOL2
3 - first digit envelope, the second digital conditional length of the stator core;
4 - f-independent ventilation, 2P-frequency regulation, with increased slide.
5 - the number of poles (2; 4; 6; 8; 10; 12);
6 - B-Temperature protection,
7 - the designation of the climatic execution of the engine according to GOST 15150 (y; T; m; TV);
8 - designation of the category of engine placement according to GOST 15150 (3; 4);

An example of recording engine designation AO2-32-4U3 voltage 220 / 380V, 50Hz network frequency, 3 kW, version IM1081 with input device K-3-1:

9.9.4. Multi-speed engines of the A2 series, AO2

The A2 and AO2 series engines were intended to drive mechanisms with stepped speed adjustment. They were developed on the basis of Hell of the AOL2 series 1 - 3rd dimensions and AO2 3 - 9 of the dimensions in the capacity range from 0.43 to 45 kW. Degree of protection AD - IP44 according to GOST 17494-72. Nominal mode of operation is a long S1 according to GOST 183-74. Technical data Hell of the AO2 series for nomin

the taxi mode of the Raoota, depending on the speed of rotation, is listed in Table. 9.62. The ratio of the minimum torque in the starting process to nominal when turned on to the largest rotation frequency is 1, for the remaining speed of rotation - 0.8.
