Simulation of ۸ and۱۶ polar magnetic bearing operation using finite element

Abstract:Nowadays, compared to the past, the growth of technology in suspension systems have led the magnetic bearings to a more powerful and economical design. Such bearings proved to have lots of benefits such as performance capability in high speeds and the ability to perform action without lubrication in different performances. That cause a decrease in the environmental and system pollution and makes it possible to work in vacant environments. Such bearings which work without friction show to have little attrition. In This paper, investigates the operation of magnetic bearing having ۸ and ۱۶ polar at a velocity rate at ۳۰۰۰۰ rpm and gap tolerance ranging from ۲ to ۰.۵ mm. The magnetic for condition simulates based on finite element by optimizing the best mesh measurement.
