This paper describes a new method of deriving greater torques per unit volume from Permanent magnet (PM) machine configurations. The method involves splitting of the stator teeth in order to introduce a magnetic gear ratio in to the torque equation. Also some of the theory and mathematical equations behind the design of the new split teeth machine have been shown and descried. Two different initial designs of the new machine topology have been developed using two dimension (2D) finite element (FE) simulations and compared to a convectional brushless DC Machine of the same dimensions. Gains of output torques of all three machines designed were shown for the purpose of comparison.
