Design analysis for a solenoid blood pump actuator.

An analysis of a solenoid suitable for direct actuation of a physiological blood pump is carried out in this paper. A general theoretical study of the electromechanical energy conversion process in the solenoid is presented, as well as a discussion of the characteristics of the magnetic circuit configuration. A computer program is described which is based on these results and is used to optimize the solenoid design with respect to conversion efficiency.
