Abstract:
1. Method for controlling the power of electronically switched two-phase reluctance machines with direct transmission of the demagnetization energy of a switched-off phase to the following phase, characterized in that the switching-on of the main current (lp) takes place delayed by a duration (t) after the phase commutation, wherein between the locking of the power switch ( 21 X) of a phase (X) and the current conducting phase of the switch ( 21 Y) of the following phase (Y), the self-induction voltage Ua, which arises by the switching-off of the phase (X) at the connection between the main winding ( 112 X) and the power switch ( 21 X), is supplied over a bypass diode ( 22 ) to a phase (Y, X, Y) which is not separated from the source of current, wherein the rise-delay time (t) of the main current depends on the number of revolutions and arises from the superposition of the complementary phase commutation signals with form similar signals which are phase-shifted with respect to the first ones by an angle (v) which is independent of the number of revolutions.
