Calnetix Technologies' Lubell, Hawkins to Teach Short Course, Tutorial at Annual Pump & Turbomachinery Symposium Next Week

September 17, 2014

Lubell’s workshop to cover gas foil and magnetic bearings for oil-free rotating machinery; Hawkins to go over new active magnetic bearing requirements for compressors

Cerritos, California – September 17, 2014 – Calnetix Technologies, a pioneer in high-speed permanent magnet motor generators, power electronics and magnetic bearings for a variety of applications and industries, announced today that Dan Lubell, Manager of Rotating Machinery, and Larry Hawkins, Director of Technology, Magnetic Bearings will present at the annual Pump and Turbomachinery Symposia in Houston next week.

Lubell’s all-day short course on Monday will cover gas foil and magnetic bearings for oil-free rotating machinery, and Hawkins’ 90-minute tutorial will go over new American Petroleum Institute (API) active magnetic bearing requirements for compressors.

“Along with my co-presenter, Luis San Andres from Texas A&M University, we’ll provide practicing engineers with a comprehensive review of existing gas foil bearing technologies that includes their principles of operation, analysis and experimental verification and comparison amongst other gas bearing types as well as the integration of gas foil bearings into actual rotor-bearing systems, both hot and cold,” said Lubell. “We’ll also include an introduction to magnetic bearings and their applications in oil-free micro turbomachinery.”

Hawkins’ program will take place from 10:30 a.m. to Noon on Wednesday and include co-presenters Erik Swanson of Xdot Engineering and Analysis and Andrea Masala of Waukesha Bearings.

“Active magnetic bearings (AMBs) are being used in an increasing number of compressors for the oil and gas industry. The applications include cryogenic compressor-expanders, subsea processing, pipeline and other processor compressors,” said Hawkins. “To address the more widespread use of AMB supported rotors, the 8th edition of API 617 includes a new annex which, for the first time, presents an extensive set of specifications that AMB supported compressors and compressor/expanders must meet for API service. The tutorial presents a brief review of AMB concepts, AMB impact on rotordynamics, a discussion of the new requirements and their rationale, and a case study. It is intended for engineers designing, specifying and reviewing AMB machinery that must meet the new API specs.”

In addition to the courses above, Calnetix will exhibit its latest technology at stand 701 in the Pump and Turbomachinery Symposia Exhibit Hall at the George R. Brown Convention Center.
