Feasibility Study on Inductively Driven Shaftless Centrifugal Pump for Biomedical Applications

By combining power electronics, innovative induction machine design, and centrifugal pump principles, a distinct design of the shaftless and compact pump device has been proposed. The mathematical model of the proposed device has been derived. Three-dimensional finite element method was applied to analyze the performances and to verify the mathematical model of the device. An experimental test-rig was fabricated. Both the analysis results and the experimental measurements support the feasibility of the system. The advantages of the proposed design, such as being shaftless and having far less risk of leakage or contamination of the fluid to be pumped, make it significant in biomedical and bioengineering applications
