SINGLE-PHASE COMMUTATOR MOTOR Russian patent published in 2008 - IPC H02K27/22 

FIELD: electricity.

SUBSTANCE: invention is related to electromechanics and may be used in AC electric drives. In suggested single-phase commutator motor excitation windings are used as well as compensation winding, which have independent excitation with program control, independent switching system, which contains windings of additional poles with independent excitation of dissimilar poles with program control, additional poles with tips beveled in relation to geometric neutral so that their axis of symmetry is axis of main poles, sensors of anchor current, transformer EMF (electromotive force) and angle speed, and also device of input-output, microcontroller, to the inlets of which signals arrive from mentioned elements.

EFFECT: minimisation of unbalanced electromotive force in switched sections of anchor winding, provision of regulated compensation of magnetomotive force of anchor and realisation of preset mechanical characteristics.
