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. The first release of a unified series of asynchronous 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.

Asynchronous electric motor, which is distinguished by its basic design, with 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, separation of internal parts from external environment shell, which is protection against ingress of water and small objects. You can buy an electric motor of any configuration in our company at an affordable price.
