Vorrichtung zur Steuerung einer elektrischen mehrphasigen synchronen Rotationsmaschine und eine elektrische mehrphasige synchrone Rotationsmaschine mit einer derartigen Vorrichtung

摘要

The device (2'') has generation units for generating output signal representing an angular position of a rotor. A digital table (20) has memory location storing digital words addressed by a rotor angular position signal (theta(t)) and delivering binary control signals (200-202) whose number is equal to number of phases. Each control signal controls switching of a high power switch (250H) and a low power switch (252B) along a temporal sequence predetermined based on an instantaneous value of the rotor angular position signal.
