Beschreibung
Zusammenfassung:	FIELD: electrics. ^ SUBSTANCE: invention concerns electric equipment and can be applied in control of electric machines with both commuted and non-commuted magnetic flux density, applied in domestic appliances. Electric machine, such as commuted induction motor, includes rotor and at least one electric phase winding. During motor manufacturing control chart is obtained, containing defined lead angle profile which depicts feed voltage form of phase winding with account of angular position of rotor within rotor rotation range. The data is stored in control unit memory together with angle correction index applied to given lead angle profile part. Angle correction index compensates difference between given input voltage and measured input voltage. Correction index can be transmitted to control unit by radio signals. ^ EFFECT: simplified control process for electric machines operating at high rates. ^ 10 cl, 10 dwg
