Cerritos, California – June 9, 2015 – Calnetix Technologies, a leader in high-speed permanent magnet motor generators, power electronics and magnetic bearings for a variety of applications and industries, announced today that Developmental Engineer Rasish Khatri will present at the ASME Turbo Expo in Montreal, Canada next week.
The paper to be presented on June 16 is entitled “Demonstrated Operability and Reliability Improvements for a Prototype High-Speed Rotary-Disc Atomizer Supported on Active Magnetic Bearings,” and is co-authored by Khatri, Calnetix Co-Founder and Director of Technology for Magnetic Bearings Larry Hawkins and Dedert Director of Product Development Claude Bazergui.
“Together with our OEM partner Dedert, we designed and fabricated a technically advanced rotary-disc atomizer driven by a permanent-magnet electric motor and supported by active magnetic bearings,” said Khatri. “The atomizer, which is part of a larger spray-dryer system, was installed and tested at a pharmaceutical-processing plant, and we had to overcome several challenges imposed on the bearing system by the atomizing process.”
“We experienced large, highly-dynamic rotor imbalances and large, quasi-periodic external radial impulses on the magnetic bearings,” said Hawkins. “A novel impulse detection and recovery system was introduced to alleviate the effects of external impulses and additionally, several design changes were systematically implemented to mitigate the effects of the unusual rotor imbalances. These changes were successful in improving the operability and reliability of the machine, and we’re looking forward to sharing our findings.”
Calnetix also will be exhibiting and featuring a new booth, #704, at the ASME Turbo Expo, which is now in its 60th year of bringing together the best and brightest experts from around the world to share the latest in turbine technology, research, development and application in gas turbines, steam turbines, wind turbines, fans/blowers, Rankine cycle and supercritical CO2.
