FIELD: transformation equipment engineering, namely, engineering of transformers for converting constant voltage to alternating voltage for powering synchronous hysteresis electric motors, in particular, gyroscopic devices.
SUBSTANCE: in the method firstly launching alternating voltage is injected into synchronous hysteresis electric motor at frequency twice below working frequency, then frequency is increased up to working frequency, then launch voltage is reduced to working voltage. Device contains contact for connecting power, contact for connecting load, regulating organ, inverter, set-point generator, phase splitter, timer, frequency switch.
EFFECT: reduced readiness time.
