In this study, a bearing and motor system of the right heart pump was designed for a continuous flow total artificial heart. We evaluated the performance of the motor in the winch examination. Also, we examined the influence of the gap between the stator and the rotor under the constant drive voltage condition. The gap was changed from 1.0 mm to 2.5 mm. The motor with larger gap has higher rotational speed coefficient, and lower torque coefficient. On the other hand, the motor with smaller gap has lower rotational speed coefficient and higher torque coefficient. In shaft output, we could not find significant difference with the operational range. The motor with larger gap has lower efficiency when the torque is larger than 5.0 mNm. The motor with larger gap has higher efficiency when the torque is smaller than 5.0 mNm.
