Abstract
The Numerous lift installation require two speeds of rotation for the work. One of them is necessary for lifting, and another for exact stop of a cabin at a level of a floor. Now in these installations two speed motors with two separate windings are used. In this paper the opportunity of creation of the highly effective two-speed motor with pole-changing winding for lifts and elevator installations is considered. The industrial test results of motors with such windings are shown. The advantages of motors with pole-changing windings over conventional motors with two separate windings are given.
