ABSTRACT

The paper deals with a technical-economic analysis of variable speed low power induction motors used in medical equipment drive systems. The study aims at developing of high performance electric drives for medical equipment, with high-speed response and exploitation even closer to the stability limit of induction motors. It appears that in the current economic and technical context, an interference is very necessary between the optimal design of the induction motor in steady state and its performance when operating at variable speed. Computer Aided Design becomes a digital lab, where prototypes are built and tested. In this case, the costs involved for experimenting are zero, and operation of the machine at variable voltages and frequencies is guaranteed. The research carried out showed that a constant torque operation, for minimal voltage and frequency, means a decrease in engine efficiency with 11.7% for the same usable power.
