May enable smaller implantable artificial hearts; leaves open in vivo durability and clinical translation.
Linear pulse motors designed for artificial hearts demonstrate significantly higher motor constants and loading ratios compared to conventional rotary motors, indicating potential for further miniaturization of totally implantable artificial hearts.
Yamaguchi et al. (1997) studied Heart Failure (Artificial Heart Development). Linear pulse motor (LPM) vs. Rotary motors (brushless DC motors) was evaluated on Motor performance (kinetic thrust, velocity, loading ratio, and motor constant). The linear pulse motor designed for artificial heart driving achieved a kinetic thrust of 77 N at 80 mm/s, with a loading ratio over eight times larger than industrial rotary motors.
