Calnetix Technologies Adds Another Magnetic Bearing Patent to Its Portfolio

Calnetix Technologies recently received a patent on the company’s radial magnetic bearing invention.  It is the fifth patent spearheaded by Principal Research Engineer Alexei Filatov.

“Our invention pertains to applications requiring large radial clearances between stationary and rotating parts, such as pumps, fans and compressors, and more specifically for hermetically sealed systems,” said Filatov. “For example, the requirement may arise when the rotating part is submerged into some sort of a chemically aggressive liquid or a gas that has to be isolated from the stationary part of a machine by means of a hermetically sealed can.”

The large clearances that are now practical with this new invention make Calnetix’s patented magnetic bearings a suitable choice for systems where sizeable particles are present in the processing gases or fluids, which could cause damage to a machine utilizing traditional magnetic bearings with smaller gaps. As another example, large clearances may be needed when pumping delicate liquids, such as blood, where small clearances would result in large shear forces that could destroy the cells.

“We’re proud of Alexei and the rest of our team for their insatiable desire to forge new grounds and design systems to better meet market needs,” said Vatche Artinian, Co-Founder, chairman and CEO of Calnetix Technologies. “This high level of ingenuity permeates throughout the company and is a reason why we remain at the forefront of high-speed permanent magnet motor generators, power electronics and magnetic bearings.”
