Способ регулирования скорости асинхронного двигателя, подключенного через тиристорный коммутатор к питающей сети, при котором изменяют частоту однофазного питающего напряжения, подаваемого на статорную обмотку двигателя путем подачи управляющего напряжения на тиристоры коммутатора, отличающийся тем, что управляющее напряжение одновременно подают на два тиристора одной группы вентилей коммутатора и один тиристор другой группы вентилей, подключенных к трем фазам статорной обмотки двигателя, затем через интервал времени, равный tинт = T/2n, где Т - период напряжения питающей сети; n - целое число в интервале от 1 до 10, отключают управляющее напряжение на одном из двух тиристоров одной группы вентилей коммутатора и одновременно подают управляющее напряжение на тиристор другой группы вентилей коммутатора, подключенный к той же фазе статорной обмотки двигателя, после чего цикл переключений повторяют.A method of controlling the speed of an induction motor connected through a thyristor switch to a supply network, in which the frequency of a single-phase supply voltage supplied to the stator winding of the motor is changed by supplying a control voltage to the switch thyristors, characterized in that the control voltage is simultaneously applied to two thyristors of one group of switch valves and one thyristor of another group of valves connected to the three phases of the stator winding of the motor, then after a time interval equal to t int = T / 2n, where T is the period of the supply voltage; n is an integer in the range from 1 to 10, the control voltage at one of the two thyristors of one group of switch gates is turned off and simultaneously the control voltage is applied to the thyristor of the other group of switch gates connected to the same phase of the stator winding of the motor, after which the switching cycle is repeated.
