Electric motor fed by direct or rectified current

Claim 1

IN THE COMBINATION COMPRISING A VARIABLE RELUCTANCE MOTOR HAVING AN INDUCTOR CONSTITUTED BY A MAGNETIC CIRCUIT INCLUDING A FIRST GROUP OF PROJECTING POLES AND A FIELD WINDING, AND AN ARMATURE CONSTITUTED BY A NON-WOUND AND A NON-POLARIZED MAGNETIC CIRCUIT WITH A SECOND GROUP OF PROJECTING POLES, AND MEANS FOR FEEDING SAID WINDING OF SAID INDUCTOR FROM A DC SOURCE AND COMPRISING AN ASTABLE OSCILLATOR INCLUDING AN RC CIRCUIT FOR DELIVERING UNIDIRECTINAL VOLTAGE IMPULSES OF WHICH THE FREQUENCY IS DETERMINED BY SAID RC CIRCUIT, MEANS FOR CONTROLLING SAID FREQUENCY ACCORDING TO THE LOAD OF THE MOTOR, THE LATTER SAID MEANS COMPRISING AN ARRANGEMENT OF THE POLE STRUCTURE OF THE MAGNETIC CIRCUIT OF THE MOTOR ADAPTED TO CAUSE THE RELUCTANCE THEREOF TO BE PROGRESSIVELY VARIED IN EACH CYCLE CORRESPONDING TO A ROTATION BY ONE POLE PITCH DURING A ROTATION OF ABOUT HALF OF SAID POLE PITCH BETWEEN THE POSITIONS WHEREIN THE REAR EDGES OF THE POLES OF THE STATOR ALIGNED WITH THE FORWARD EDGES AND WITH THE REAR EDGES OF THE POLES OF THE ROTOR RESPECTIVELY, AND CIRCUIT MEANS CONNECTED IN SERIED WITH THE WINDING OF THE INDUCTOR TO PROVIDE A VOLTAGE VARIATION ACROSS ITS TERMINALS DUE TO THE VARIATION OF THE CURRENT INTENSITY IN SAID WINDING DEPENDING UPON LOAD AND SPEED VARIATION OF THE MOTOR, SAID CIRCUIT MEANS BEING CONNECTED TO THE RC CIRCUIT OF THE OSCILLATOR TO CONTRIL THE RELEASE OF THE VOLTAGE IMPULSES SUPPLIED BY SAID OSCILLATOR.
