Abstract: The invention relates to a novel 4-phase motor and generator device with increased efficiency for generating electrical energy. The device features a stator wall with eight stator slots and four pole groups, and an armature rotatable within the stator wall. The eight stator slots are divided into four pole groups of opposing stator slots, the two opposing stator slots include a N stator slot and a S stator slot. N and S stator slots are alternatively activated in response to rotation of the armature. The activation of the pole groups results in a rotating magnetic field within the stator wall, and only six of the eight poles are actively coupled in any given configuration. The invention also includes a method of operating the motor for generating electrical energy with increased efficiency and an environmentally friendly manner compared to conventional motors.
