Скачать или смотреть omniCOOL system from CUI Inc. uses magnetic bearings for improved performance in dc fans

CUI Inc’s dc fans keep electronics cool in an array of designs. Here, Design World editors review how CUI’s fans built with the omniCOOL™ system use magnetic rotor balancing, along with an engineered sleeve bearing to improve performance and allow for operation at any angle.

This magnetic structure sits in front of the rotor — and because its flux is parallel to the rotor shaft’s axis, it uniformly attracts the whole rotor. Using magnetic repulsion means the fan shaft and bearing sleeve bear no rotor weight. What’s more, the magnetic field lowers the fan’s center of gravity by pulling the shaft downward to minimize tilt and wobble issues associated with traditional sleeve bearings, while dramatically reducing friction.
