Zusammenfassung:electrical engineering; electromechanical engineering; variable-speed motors. SUBSTANCE: proposed single-layer winding is wound at pitch Y = Z1/8; its coil number is a multiple of 36 with three parallel circuits per phase; circuits of one phase are connected to star of two other phases; it has six leads of which three ones, 8C1, 8C2, 8C3, are designed for connecting motor to supply mains at 2p = 8 and three other leads, 6C1, 6C2, 6C3, for its connection to supply mains at 2p = 6. EFFECT: reduced input of expensive insulating materials, facilitated winding operation, extended range of active material application at all speeds. 5 dwg
