Claw teeth motors have a feature that can make axial the length thin. This makes them suitable for appliances, automobile assistant machines, and small-sized industrial motors. On the other hand, there is a need to thin HEVs, elevators and large-sized industrial motors. In this study, we examined a higher output of the claw teeth motor. We arrived at the following conclusions as a result of our research. 1) The optimal stator structure was determined and the prospect of attaining the specification of 123N·m was determined. 2) A manufacturing subject called core assembly accuracy reservation, thin coil manufacture, and the rotator insertion method became clear. 3) The experimental results and the analysis results were in agreement with respect to the EMF. 4) The experimental cogging torque results and FEA results are in agreement in the 6th degree. But the 2nd and the 4th degrees of the experimental cogging torque results did not agree with the FEA results. 5) Although the core needed to be divided in the direction of the circumference for enlargement, it was clear that the influence on the torque is small. 6) Division of the core is a good solution for enlargement of the claw teeth motor.
