A Tubular Self-Synchronous Motor for Artificial Heart Pump Drive

Buildup and test of a permanent magnet, tubular, self-synchronous motor and the associated microprocessor-based power conditioning link are discussed. The motor is controlled for variable frequency axial oscillation demonstrating suitability to function as an energy conversion intermediary between a battery pack and an artificial heart pumping element. Strengths and weaknesses of the test bed system are discussed along with future plans directed toward development of an implantable pump drive for an artificial heart.
