In this study, the enclosed-impeller type axial flow blood pump has been research and developed. This pump is mechanism to drain by turning the spindle rotor which became at one with an impeller. High efficiency, the high durability, miniaturization are demanded from the motor which is an actuator. However, magnetic flux became overcrowled in the central part of the tooth of stator, and, with the current motor, decrease of the torque was suggested. Therefore I report this article because I performed reduction of the magnetic induction in the central part of the stator and improvement of the torque by analysis. If magnetic flux is overcrowded, magnetic flux is hard to come to flow through the stator made of electromagnetic steel sheets. Therefore magnetic induction decreased by changing the shape of the tooth of stator. By this, magnetic flux was easy to come to flow, and about 17% torque improved.
