Annotation

A magnetic gearbox with a three-phase stator winding, powered by a static frequency converter with a sinusoidal current, which is in phase or in antiphase with the EMF of the idling winding, will have in this mode the maximum values ​​of the electromagnetic moments of the shafts proportional to the stator current. Such a gearbox will have no “overturning” of the rotors as long as the frequency converter is able to increase its current with increasing load.

The electromagnetic moments of the rotors of the magnetic gear are a consequence of the presence of the electromagnetic moment of the stator. The electromagnetic moments of the rotors are rigidly related to the electromagnetic moment of the stator through constant coefficients.

A mathematical model of an adjustable magnetic gearbox with a three-phase stator winding and the results of modeling a dynamic system are presented. Offers the structure of the output shaft speed stabilization system, such as a wind turbine. The introduction of the main research results is illustrated.
