Electrically controlled magnetic movement
Abstract
Abstract THE ELECTRICALLY CONTROLLED MAGNETIC MOVEMENT COMPRISES A PERMANENT MAGNET ACTING AS A ROTOR, AND A STATIONARY ELECTROMAGNET OR STATOR HAVING THREE POLES SPACED AROUND THE ROTOR. TWO POLES OF THE OPPOSITE POLARITY ARE ABOUT 180* APART, AND A THIRD POLE HAVING THE SAME POLARITY AS ONE OF THE TWO POLES IS DISPOSED ABOUT 90* FROM THE FIRST TWO POLES. THE ROTOR ASSUMES A REST POSITION BETWEEN FIRST TWO POLES. WHEN THE ELECTROMAGNET IS ENERGIZED THE ROTOR TURNS ABRUPTLY WITH A SNAP ACTION TO A NEW POSITION GENERALLY TRANSVERSE TO ITS REST POSITION. THIS IS DONE WITH GREATLY INCREASED TORQUE COMPARED TO PREVIOUSLY KNOWN MOVEMENT OF THE DAME GENERAL TYPE. WHEN THE STATOR IS AGAIN DEENERGIZED THE ROTOR TURNS ABRUPTLY BACK TO ITS ORIGINAL REST POSITION, WITHOUT NEED FOR A RESTORING SPRING. STOP MEANS ARE EFFECTIVE TO LIMIT THE ROTATION OF THE ROTOR TO SOMEWHAT LESS THAN 90*.
