Abstract

AN AC PERMANENT MAGNET SYNCHRONOUS ELECTRICAL MACHINE INCLUDES A STATOR (1) AND A ROTOR (2). AN AIR GAP (7) IS PROVIDED BETWEEN THE OUTER CIRCUMFERENCE OF THE ROTOR (2) AND THE INNER WALL OF THE STATOR (1). THE MINIMUM AIR GAP LENGTH OF THE AIR GAP (7) IS Gmin, AND A MECHANICAL ROTATING ANGLE OF A POSITION WITH THE MINIMUM AIR GAP LENGTH IS ZERO DEGREE. THE NUMBER OF THE POLE PAIRS OF THE ELECTRICAL MACHINE IS P. AN AIR GAP LENGTH OF A POSITION WITH AN ELECTRICAL DEGREE OF P.? IS G(P.?). G(P.?) OF A POSITION WITHIN A CERTAIN ELECTRICAL DEGREE RANGE IS INVERSELY PROPORTIONAL TO A COSINE FUNCTION OF THE ELECTRICAL DEGREE. (FIGURE 4)
