Abstract (en)

[origin: WO0074205A2] The invention explains principles and circuits for the power control of two-phase SR-Machines featuring a direct recovery of the phase switch-off energy and a 180 DEG phase angle at full load. The power control relies physically on a shorter current flow (duty cycle) at the phase beginning. This can be done either through mechanical phase shift of a second Hall sensor or by using time delay circuits.
