| Abstract |
The paper deals with powerful step motors designed for numerical control of machine tools, industrial manipulators and robots. An equation concerning the instantaneous value of the electromagnetic torque has been derived following the analysis of the instantaneous state of the energy and the co-energy of the magnetic system of the motor phases. This allows for the calculation of a family of curves expressing the function average torque - initial angle of the switching on of the phase (the average dynamic error) for a given control frequency. The possibilities to drive the motor with shortened pulses as well as operating it in autocommutation mode and the combination of these two ways of control for achieving maximum torque have been studied. |
