Asynchronous motors for general industrial purposes of types A2 and AO2 are designed for continuous operation from a three-phase alternating current network.
The ratings (power, current, voltage, number of revolutions, efficiency) refer to the nominal values of climatic factors external environment and minimum ambient temperatures: -40°С during operation and -45°С during storage.

Electric motors of all dimensions are manufactured with six output ends. Winding connection scheme - "triangle", "star" and triangle / star at the request of the customer.
The engines have similar designs to the currently produced AIR series in terms of the degree of protection against environmental influences:

closed version (IP44) (IP54) made of cast iron (АО2) - size 3 to 9;
closed version (IP44) (IP54) made of aluminum alloys (AOL2) - sizes 1 to 3

The structure of the designation of the electric motor consists of marking the design according to the degree of protection (AO2, AOL2), designating the type of the 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 design and category of accommodation.
Symbol example:
AO2-62-4U3 - an electric motor of a closed ventilated version with a frame and shields made of cast iron, size 6, 2nd core length, four-pole (1500 rpm), climatic version U, placement category 3.

STRUCTURAL SCHEME OF DESIGNATION OF ENGINES

The AO2 multi-speed electric motor is used in the drive of mechanisms with step speed regulation. The power of the AO2 multi-speed motor is set based on certain conditions. First release of a unified single series induction motors with general purpose AO was carried out in 1949. This series has now been discontinued. Since 1961, the second single series of AO2 asynchronous electric motors has been produced.

Features of AO2 electric motors

Despite the fact that this series has been discontinued, electric motors do not cease to be popular. The equipment of the old series has a rather long service life.

Over time, such equipment was successively replaced by a series of engines 4A, 4AM and then - AIR. It should be noted that AO electric motors have significant differences in dimensions, in comparison with motors of the 4A, 4AM, AIR series. So far, reliable operation of AO2 series engines has been carried out. Therefore, many are interested in information regarding the description, specifications and dimensions of this equipment. With some information, it will not be difficult to find a replacement.

The asynchronous electric motor, which is distinguished by its basic design, with the presence of a squirrel-cage rotor of the AO2 series, is designed to drive certain mechanisms that are not characterized by any special requirements for characteristics regarding slip, environmental conditions, and energy performance. The basic version can be represented by several electrical modifications.

For rotors of electric motors of the AO2 series of the main execution aluminum filling is characteristic. An increased starting torque is achieved by using a special shape of the grooves, and an increased nominal slip is achieved by filling the rotor with silumin (an alloy of aluminum and silicon). For electric motors with a closed ventilated design, a compartment is provided internal parts from the external environment with a shell, which is a protection against the ingress of water and small objects. You can buy an electric motor of any configuration in our company at an affordable price.

To drive woodworking machines, asynchronous electric motors of a new series (closed, ventilated and protective) are used. Electric motors of this series with a cast-iron housing are designated A, and with an aluminum housing - AL. The letter O is added to the designation of closed electric motors, indicating that the electric motor is blown (AO, AOL). After the designation A and AL, three digits characterize the electric motor: the first digit indicates the outer diameter of the stator package, the second is the length of this package in arbitrary units, the third digit indicates the number of poles.

Asynchronous electric motors of a single series are produced for standard voltages of 127/220, 220/380 and 500 V, with the connections of the stator windings, respectively: triangle to star, triangle to star and star.

Instead of electric motors of the A and AO series, since 1961 a new series of electric motors has been produced. It has better energy performance, as well as smaller dimensions and weight. A new series of electric motors is designated with the addition of the number 2 (A2, A02, AK.2, etc.). Based on the basic design of electric motors of types A2 and A02, modifications AP2 and AOP2 with increased starting torque are produced; AC2 and AOC2 electric motors with increased slip; AK2 electric motors with a phase rotor; electric motors A2 and A02 are multi-speed.

These electric motors are produced for voltages of 220/380 and 500 V with increased starting torque and a squirrel-cage rotor. Execution closed, blown. Form of execution M-101.

The main technical data of electric motors of the AOP2 series are given in Table. fifteen.

THREE-PHASE ASYNCHRONOUS ELECTRIC MOTORS VAO SERIES EXPLOSION-PROOF

These electric motors are produced with a squirrel-cage rotor. They are designed to work in installations with the possible formation of firedamp "(methane), with the presence of explosive coal dust and vapor, gas-air mixtures of 1, 2, and 3rd category of flammability groups. Form of execution - M-101.
