Winding two-speed engines with a large number of pairs of poles.
Abstract
Schemes of pole-switching windings with a ratio of pole numbers of 12: 2 and 24: 2 are proposed. The diagrams of switching on the windings of two-speed asynchronous motors are given. It is shown that due to the independence of the winding leads (for each of the number of pole pairs), such motors can be widely used in industry.
