Variable Characteristic motors which can change the magnet flux have been focused since these motors can improve the low load efficiency and also can reduce the magnet quantity. This paper introduces 2 new motors, the one has a changeable winding connection; named as Matrix Motor and another one has compounded magnet-motive forces; named as CMMF motor. These motors are realized by integration of motor and power electronics.
