Electromagnetic vibrator employing rectification of induced currents
Abstract
Abstract THE MOTOR OF AN ELECTROMAGNETIC VIBRATOR COMPRISES A FERROMAGNETIC CORE ARRANGED WITH WINDINGS ENERGIZED WITH ALTERNATING CURRENT AND DIRECT CURRENT, IN WHICH THE DIRECT CURRENT EXCITATION PREFERABLY EXCEEDS THE ALTERNATING CURRENT EXCITATION. THE DIRECT CURRENT FOR A WINDING MAY BE SUPPLIED FROM THE POWER LINE THROUGH RECTIFIERS OR MAY BE INDUCED IN THE WINDING, CLOSED BY A UNILATERAL CONDUCTOR, BY TRANSFORMER ACTION FROM ANOTHER WINDING ENERGIZED WITH ALTERNATING CURRENT. SINCE THE FORCE OF AN ELECTROMAGNET VARIES AS THE SQUARE OF THE FLUX ACROSS THE AIR GAP, THE PRESENCE OF THE DIRECT CURRENT FIELD INCREASES THE EFFECTIVENESS OF THE ALTERNATING CURRENT IN DRIVING THE VIBRATOR.
