DEVICE FOR MATCHED ROTATION OF ASYNCHRONOUS MOTORS |
摘要 |
FIELD: electrical engineering.SUBSTANCE: invention relates to electrical engineering and can be used in electrical engineering. Device for matched rotation of asynchronous motors comprises two double-speed asynchronous motor with short-circuited rotors, each having two independent groups of windings at stator. Outputs of first groups of stator windings of two-speed asynchronous motors with squirrel-cage rotor are connected to supply mains. Outputs of second groups of stator windings and zero point of two-speed asynchronous motors with squirrel-cage rotor are connected with four-phase communication line. Phase link connected with unit of variable resistors, which is connected with movable contacts of three-phase switch.EFFECT: three-phase switch includes two groups of fixed contacts, first of which is connected to supply mains, and contacts second fixed group of three-phase switch connected to each other and with neutral wire communication line.1 cl, 1 dwg |
