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

FIELD: engines and pumps.

SUBSTANCE: invention relates to ACS and can be used in programmable discrete drive motor. Claimed device comprises the main four cycle reversible pulse distributor for control over stepped motor including two-digit reversible binary counter. Clock, permit and count direction inputs of the latter are connected to appropriate clock pulse, control and reverse buses. The latter are group inputs of said distributor. Besides, it comprises two inverters and XOR elements. Note here that additionally this device incorporates 1^st and 2^nd standby distributors, unit of majority gates, 1^st and 2^nd sets of XOR of fault address detection unit. First outputs of the main and standby distributors are connected to 1^st…3^rd inputs of 1^st majority gate. Second outputs of the main and standby distributors are connected to 1^st…3^rd inputs of 2^nd majority gate. Third distributor outputs are connected to 1^st…3^rd inputs of 3^rd majority gate. Third distributor outputs are connected to 1^st…3^rd inputs of 3^rd majority gate. Outputs of majority gates are connected via power amplifiers to windings of stepped motor to make the 1^st group output of the device. 1^st and 2^nd output of fault address detection unit group are connected to 1^st…3^rd outputs of the main and standby distributors.

EFFECT: expanded operating performances, higher reliability, simplified operation.
