Development of a Linear Electromagnetic Actuator for Implantable Artifical Heart
IEEE Translation Journal on Magnetics in Japan, 1988 This paper deals with the configuration, principle of operation, and experimental results concerning a linear pulse motor for an implantable aritificial heart. The linear pulse motor is designed to be as small as possible so as to minimize the space occupied. The mover is made of laminated Permendur sheets 0.35 mm in thickness.
