DEVICE FOR PROGRAM CONTROL OVER M-PHASE STEPPING MOTOR Russian patent published in 1994 - IPC

FIELD: automatics. SUBSTANCE: device has power supply source, program setting unit, counter, control program storage, m power keys, m-phase stepping motor, OR gate, master generator, clocking unit, second pulse counter, storage of programs of control over position of rotor, second OR gate, delay gate connected in proper way. As several programs are entered into control program storage in advance then setting proper code one may timely select required step (microstep) of motor. Increased accuracy of generation of microsteps is achieved by change in program by compensation of error between required values of currents in phases of motor and values obtained experimentally thanks to input of greater number of levels of quantization of currents by two or more times than it is necessary to set required value of microstep of motor. EFFECT: expanded application field and increased accuracy of generation of microsteps of motor. 6 tbl, 5 dwg
