The invention refers to the sphere of automatics, eletrotechnics and can be used for multi-mode control of step-motors with any number of phases from 3-m with permanent magnet, variable reluctance and hybrid rotors acting in the electrical drives of executive mechanisms of robots, machine tools and computer peripherals. The aim of the invention is to simplify the device and widening of its functional possibilities. The device contains two power sources, two groups of power amplifiers, m multiplexers, m-2 regime setting buses, binary counter, logical element 2OR, polarity Yp setting bus, strokes Yt setting bus, logical elements 2NOR. The presented device favorably differs from the analogous devices by its simplicity and wide functional possibilities. Altogether under all possible phase switching schemes of the m-phase step motor to the corresponding power amplifiers, it provides 4(2m-3) various unipolar and bipolar regimes of phase commutation. |
