Three 5-axis Magnetic Bearing Controllers, One Cabinet

On January 4, 2017, a new active magnetic bearing-supported motor compressor went into production use at a natural gas pumping station in Japan. The installation features the first use of a new magnetic bearing control cabinet with unique control electronics packaging.

The single cabinet enclosure contains three 5-axis magnetic bearing controllers: one for the compressor bearings, one for the motor bearings, and one installed spare that can serve either the motor or compressor bearing system.

To read about the design of the motor compressor system and the application of the compact Zephyr digital controllers, download the article “Three 5-Axis Magnetic Bearing Controllers, One Cabinet,” which originally appeared in the Gastech Show Daily on April 7, 2017.

Efficient Balancing of Active Magnetic Bearing-Supported Rotors

Shafts of high-performing rotating equipment experience a certain mass unbalance distribution resulting from manufacturing tolerances, component assembly and material nonhomogeneities. The residual unbalance generates uneven forces on the rotor as it spins, resulting in vibrations and the transfer of dynamic loads to the bearings and supporting structure.

To limit the negative effects of rotor vibration, ISO and API standards set balancing criteria and acceptance levels for residual rotor unbalance. Whether magnetic or fluid film bearings are used in the machine, there is a prerequisite for spinning a rotor to its rated speed. The rotor must be balanced to meet an acceptable residual unbalance level.

The ability of an active magnetic bearing (AMB) system to tolerate high levels of unbalance on the rotor by applying unbalance force rejection control algorithms does not alter the balancing requirements. Rotors supported by AMBs and rotors supported by fluid film bearings are subject to the same balancing requirements.

In the June 2016 issue of COMPRESSORtech2, Andrea Masala of Waukesha Magnetic Bearings discusses the options and considerations in performing low- and high-speed balancing of active magnetic bearing-supported rotors. Two case studies are also discussed.

May the Magnetic Force Be With You

By Richard Shultz, Waukesha Magnetic Bearings
Published in Fluid Handling, January/February 2016

Groningen, Europe’s largest natural gas field, was discovered in 1959. Production began in 1963, and by the end of the decade nearly 50% of the field’s reserves were depleted with free-flow operation. Nederlandse Aardolie Maatschappij (NAM), a joint venture between Royal Dutch Shell and ExxonMobil, was created in the mid-1990s to find the most cost-effective way to extract gas from the field and extend the life of its reserves.

By upgrading the field’s equipment, including installation of motors and compressors, the field could supply gas to all of the Netherlands, Germany, and Belgium for an additional 40 years. The challenge was to achieve at least 87% availability and a low total cost of ownership.

Magnetic bearings are a proven technology for large standalone motor compressor strings, like the ones at Groningen, to provide both high availability and a low total cost of ownership, as well as lower power consumption (due to decreased rotating losses), lower maintenance costs, and lower CAPEX costs compared to conventional bearings.

Read the article in the January/February 2016 issue of Fluid Handling, or download it below, for more about the operating principles of magnetic bearings, system design considerations, and the application of the technology at Groningen.

Waukesha Magnetic Bearings to Present at MaintCon 2014 in Bahrain

Waukesha Magnetic Bearings, an industry leader in custom-engineered magnetic bearing systems for large turbomachinery and high-performing rotating equipment, is proud to announce that Chief Engineer Richard R. Shultz will be delivering a presentation at the third biennial Middle East Maintenance Conference & Exhibition (MaintCon), Dec. 7-10, 2014, in Bahrain. The presentation, which is co-authored by Mamdouh B. Al-Aidarous, Saudi Aramco, PE Mechanical, with Rotating Equipment & Dynamic Analysis (REDA), will focus on Bearing System Reliability and Availability, including consideration of a magnetic bearing system for an enhanced oil recovery (EOR) motor compressor.

“MaintCon 2014 in Bahrain is a tremendous opportunity to discuss the newest technologies from around the globe, and we are excited that Richard Shultz will be sharing the unique benefits of magnetic bearing systems with attendees this year,” said Jay A. Burnette, President of Waukesha Bearings Corporation™.

Shultz’s presentation will examine the design of canned magnetic bearings in a hermetically sealed motor compressor. The canning, a highly corrosion-resistant metallic lining, allows the bearings to operate directly immersed in the process gas. With the elimination of the need for shaft seals, the system’s reliability is increased, and no maintenance is required for the magnetic bearings. Specific attention will be paid to the benefits of the condition monitoring capabilities within the magnetic bearing system.

Shultz is the Chief Engineer for bearing systems at Waukesha Magnetic Bearings. He has 20 years of industrial experience designing magnetic bearing systems and auxiliary bearing systems, specializing in rotordynamics and control system design. He has recently instructed at the Magnetic Bearing Short Course at Texas A&M University’s Turbomachinery Symposium and the Middle East Turbomachinery Symposium in Qatar.

In conjunction with the presentation, all of Waukesha Bearings Corporation’s operating companies, including Waukesha Magnetic Bearings, Waukesha Bearings®, Inpro/Seal® and BearingsPlus™, will be exhibiting at the event with local partner Eastern MSAR at booth B06 and B08. Attendees are invited to talk with representatives about all the Waukesha product lines, including hydrodynamic bearings, magnetic bearings, brush seals and engineered sealing solutions.

Canned Magnetic Bearings Prove Cost-Effective

In 2002, a leading oil and gas customer approached Waukesha Magnetic Bearings with the challenge of developing a bearing for a hermetically sealed integral motor compressor. Availability and reliability were the customer’s primary objectives. The end user could achieve a significant cap-ex savings on the installation if the motor compressor could be located outdoors, with no building or enclosure required.

The sealed characteristic the Waukesha bearings and electrical connectors delivered in the end did eliminate the requirement for a costly enclosure for the motor compressor and the end user realized a significant project cap-ex savings.

Canned Magnetic Bearings Minimize Corrosion in Oil & Gas Processing

Safely immerse motor compressors in process gas without risking costly damage.

By Richard Shultz, Waukesha Magnetic Bearings
Published in Pumps & Systems, August 2014

Active magnetic bearing (AMB) reliability and availability levels have surpassed oil bearings after 10 years of technological advancements. These advances have made an impact on the industry, drawing attention from major original equipment manufacturers globally.

In 2002, an oil and gas processing company required a bearing for a hermetically sealed integral motor compressor. The natural gas from the well contained hydrogen sulfide, which led the company to pursue a corrosion-resistant canned bearing. Finding a reliable bearing for this hermetically sealed integral motor compressor was a challenge—but one worth the cost.
