Making Waves in "O" by Cirque du Soleil
Empire Magnetics, a supplier of specialty motor products, motion control systems and support services, is often called on to develop custom motion control solutions for unique applications and environments where standard motion control components are simply unsuitable. One of Empire's custom motor gearbox assemblies has even made its way into show business as an unnoticed yet essential co-star in "O" by Cirque du Soleil at Bellagio in Las Vegas, Nevada. "In June of 1999, the technical team at Cirque du Soleil contacted us because they needed a robust, submersible motion control solution to provide precise, reliable operation of a motorized, battery powered piano that had to operate in and out of water, show after show, year after year," says Richard Halstead, President, Empire Magnetics. "Additionally, because the piano must also operate in water with performers, safety precautions demanded that the motor operate at less than 24 volts,

while still providing enough power to move the piano around the stage," he says. The solution provided by Empire's team of engineers consists of a hall effect commutated three phase brushless motor integrated with a cycloidal gearbox. The gearbox assembly is integrated into the piano that is the focal point of the show's finale, which features a tank style control system where the motors spin in opposite directions, allowing it to virtually turn on a dime.

In the March 2007 edition of Marine Technology Reporter, MTR published an article entitled "PSS Positioned for Global Growth Opportunities." Due to an error in pagination, the last question/answer of the interview with Martin Anderson, CEO of Triton Group Holdings (pictured) was cut off. MTR Houston is obviously the hub for GOM offshore operations, and just as obvious is the cyclical nature of this business. What are your projections for short- and mid-term business prospects in the oil patch? Anderson The global subsea market has visible growth through 2011 with a substantial increase in the number of subsea wells and subsea developments. The GOM is forecast to maintain a steady level of activity through this period. All of the principal growth regions are deepwater with a growing demand for advanced technologies such as ours.
