Multi-speed electric motors AO2. AC asynchronous motor AOL asynchronous motor

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 external diameter stator package, the second length of this package in conventional 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 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. 15.
