When two power supplies with near-by frequencies are connected to a 2-phase induction motor, the motor generates the two kinds of oscillatory torque components, which have frequency components of the summation and the difference between the frequencies of the power supplies. These oscillatory torque components are sinusoidal and the torque with the frequency component of the difference is considerably larger than the torque with the frequency component of the summation. Consequently, the motor behaves as a swing motor, which alternately changes the direction of rotation.
Because of the regularity on the period of blood beat in human body, this swing motor is suitable for the driver of an artificial heart. We propose here to use this swing motor as the pump for the artificial heart, which is used to send the blood at an operation of heart.
In this paper, we present the fundamental theory and the characteristics on the swing motor, and the outline of the motor action for the artificial heart.
