Abstract

THIS INVENTION RELATES TO ELECTRO-MAGNETIC MACHINES CONSTRUCTED OF TWO PARALLEL CO-AXIAL ARRAYS OF PERMANENT MAGNETS FUNCTIONING AS THE ROTOR WITH INTERMEDIATELY A THIRD ARRAY OF POLE PIECES FORMED OF LAMINATIONS MAGNETISED BY COIL MEANS AS THE STATOR. ARRANGEMENTS OF THE ROTOR MAGNETS AND THE STATOR POLE PIECES ARE IN SUCH A WAY THAT A MAGNETIC FLUX PATH CAN BE PROVIDED BETWEEN A PAIR OF MAGNETS INTHE FIRST ARRAY AND A PAIR OF MAGNETS IN THE SECOND ARRAY VIA A PAIR OF THE POLE PIECES. THE MACHINE CAN BE OPERATED EITHER AS A MOTOR OR A GENERATOR BY SWITCHING THE ANGLE OF THE WINDINGS OF THE STATOR COIL AND DISPLACING THE MAGNETS OF ONE ARRAY ANGULARLY WITH RESPECT TO THE MAGNETS OF THE OTHER ARRAY; AND THESE TECHNIQUES CAN ALSO BE USED TO VARY THE TORQUE, POWER, OR SPEED OUTPUT OR THE CURRENT INPUT TO THE MACHINE.(FIG 1)
