DEVICE FOR STEPPED MOTOR CONTROL Russian patent published in 2014 - IPC H02P8/00 H02P8/20 

FIELD: engines and pumps.

SUBSTANCE: invention relates to ACS and can be used in systems with discrete drives built around three-phase, four-phase and six-phase steeped motors. Claimed device implements Hamming coding algorithm by hardware means to reveal and indicate the address of single fault. For this, proposed device incorporates 1^st, 2^nd and 3^rd convolves, reference check discharge buses, indicator, power amplifier unit with current and voltages tranducers for every phase.

EFFECT: expanded operating performances, variable timing mode controlled by switching selection buses.
