Clawtooth motors have the feature that they can be made thin in the axial direction. This makes them suitable for appliances, automobile accessories, and small‐sized industrial motors. On the other hand, there is a need for thinner HEV and elevator motors and large‐sized industrial motors. In this study, we examined ways of increasing the output of clawtooth motors. We arrived at the following conclusions. (1) The optimal stator structure was determined and the prospects of attaining the target specification of 123 N‐m were determined. (2) Three important manufacturing tasks, assurance of core assembly accuracy, thin coil manufacture, and rotator insertion, were identified. (3) Experimental results and the results of analysis were in agreement with respect to the EMF. (4) The experimental cogging torque results and finite element analysis (FEA) results were in agreement with the FEA results at sixth order but not at second and fourth order. (5) Although the core needed to be divided in the circumferential direction in order to increase its size, it was clear that the influence on the torque was small. (6) Use of a divided core is a good solution for enlargement of clawtooth motors.
