Motor Efficiency - an overview | ScienceDirect Topics
Motor efficiency is the most important factor to consider in the development of implantable devices such as ventricular assist devices (VADs) and total artificial hearts (TAHs). The electric energy that is input into the device is converted to mechanical energy by the motor. The excess energy is dissipated as heat into the surrounding tissue and blood.
