Advances compact motors for artificial hearts; leaves open clinical translation pending velocity gains and human testing.
A linear pulse motor designed for totally implantable artificial hearts demonstrated superior loading ratios and motor constants compared to conventional motors, though increased drive velocity is needed to reduce volume.
Yamaguchi et al. (1998) studied Totally implantable artificial heart (TAH). Linear pulse motor (LPM) vs. Linear oscillatory actuator, brushless dc motors, and ultrasonic motor was evaluated on Mechanical output/volume ratio and the motor constant. The linear pulse motor achieved a kinetic thrust of 77 N and velocity of 80 mm/s, with a loading ratio over eight times larger than industrial rotary motors.
