Improving the efficiency of electric machines using ferrofluids

Abstract: Ferrofluids have a growing importance in technical and medical applications since stable suspensions of magnetic nanoparticles in carrier fluids can be produced. The application of these strong paramagnetic fluids in electric machines by filling the air-gap between stator and rotor to increase the force in linear and the momentum in rotating machines offers an interesting possibility to improve efficiency and thus to save energy. Some calculations of this effect are presented here, including the method of magn… Show more

“…The Taylor-Couette ferrofluid flow has found some technological applications such as in making ferrofluid rotary seals. Ferrofluids have application in the electric motors by filling the air-gap between stator and rotor to improve efficiency and thus to save energy (Nethe et al, 2006). Numerous experiments have been conducted to understand the internal flow and the magnetization in the Taylor-Couette ferrofluid flow.…”

“…São também usados para melhorar a eficiência de máquinas eléctricas. O ferrofluido é colocado entre o estator e o rotor para aumentar a força e a quantidade de movimento em maquinas rotativas (Nethe et al, (2006)). São utilizados também em equipamentos tais como o de ressonância magnética por imagem (Pouliquen, ( 1989)) e em técnicas de separação magnética (Safarik e Safarikova, (1999)).…”
