| Abstract |
The paper proposes the change of strategy of controlling the stepping motors using the field-oriented control, by taking over control principles from a.c. motors. In this purpose the identification of a representative PM-hybrid stepping motor is first made, taking into account an equivalent system of magnetic axes, which replaces classical identification in the geometrical system of axes and leads to the definition of the space-phasor. Then system- and axis-transformations for a four-phase system of magnitudes are presented and the resulting rotor-oriented model is deduced. On this base field-oriented control of PM-hybrid stepping motor is described and a particular illustrative self-commutating stepping motor control system is proposed. |
