【Abstract】 A new control system of the brushless motor was designed for driving the impeller blood pump. Instead of using rotor position sensor, the peripheral position of the rotor was detected by measuring the inductive voltage in the motor coil, produced by rotor magnets. The results demonstrated that the reliability and performance property of the motor were improved, the motor length and control wires were reduced. It has made the blood pump more convenient for clinical use.更多还原
