The hydrodynamic bearing can reduce the power consumption and the size of rotary blood pumps. Tilt-controllable motors have been developed to work in conjunction with hydrodynamic bearing to permit stable levitation and rotation. Tilt-control motor (TCM) can rotate a rotor and control its tilt angles with an actuator. Hybrid Magnetic Bearing (HMB) is for the exclusive use of tilt angle control. The height and the diameter of TCM are 20 mm and 36 mm, respectively. The height and the diameter of HMB are 4.5 mm and 36 mm, respectively. The results of electromagnetic field analysis show that TCM has sufficient performance. Developed TCM can generate a motoring torque of 26 mNm at 2600 rpm above target torque. The results of analysis show that HMB can generate tilt-control torque. Developed HMB can produce tilt-control torque of 47.6 mNm which is approximately equivalent to analytical value.
