In this paper, to provide a reduction in the size and weight of a motor, improvements in the torque density by the use of a three-dimensional bent core were examined. A motor using a three-dimensional bent core can collect flux leakage. The torque density could be improved by 10% by effectively using the magnetic flux. As a result, reductions in the size and weight of the motor are possible, and an increase in the performance of an automobile or a robot can be expected.
