Study on Driving Motor for Magnetic Levitated Artificial Heart Pump

H. Wang, S.Q. Liu

Abstract


A driving motor and its control system for magnetic levitated artificial heart pump are introduced. On the basis of traditional brushless DC motor, the stator removes slot and adopts coreless winding. The advantage of slotless stator and the design are introduced. The control system is designed based on back EMF method to control sensorless motor. IC ML4435 is used as the central control chip. The speed can be governed smoothly by adjusting the input voltage. The advantage is simple and has low power consumption.
