Siemens Celebrates 20 Years of Perfect Harmony and Announces Peter Hammond Scholarship Recipient

By Business Wire News   


To honor Peter Hammond, inventor of the Perfect Harmony drive, Siemens announced today that it will fund a $40,000 collegiate scholarship in his name. The Siemens Peter Hammond Scholarship Fund will be awarded to an undergraduate student who has achieved outstanding academic success in the Department of Electrical and Computer Engineering at University of Pittsburgh Swanson School of Engineering.

Siemens is celebrating the success of Hammond and the 20th anniversary of the Perfect Harmony drive with an employee picnic at the company’s New Kensington facility near Pittsburgh on Aug. 9. Employees and their family members are invited to attend and tour the world-class factory.

“I am privileged and honored to celebrate these two milestones with our employees and the customers we serve,” said Anne Cooney, President, Process Industries and Drives, U.S. “To be able to invest in our future with the Siemens Peter Hammond Scholarship Fund is a true reflection on the cornerstone we built with Perfect Harmony and have continued to nurture and develop.”

The Perfect Harmony drive came into existence in 1994 after Hammond concocted the idea and put thoughts into action. Hammond was working on scaling up a low-voltage drive design for medium-voltage, when he had a better idea: a modular, scalable and power-quality compliant, medium-voltage variable frequency drive (VFD) system. Twenty months later the first PERFECT HARMONY prototype — a 1,000 hp VFD capable of 4160 volts output — was successfully tested with more than 5,000 feet of submersible medium-voltage cable. When the drive went into production, its business grew exponentially.

More than 13,000 Perfect Harmony drives are used across the globe today, and around 70 percent of all medium-voltage, variable frequency drives produced globally are based on the original Perfect Harmony topology. The drive is crucial in several industries, including oil and gas and power generation. The drive is used by industries worldwide to control motors, which drive pumps, fans, conveyors and compressors that give people the standard of living they enjoy today. The frequency of electricity that goes into the motor is often varied to make it go faster or slower, allowing its speed to match what’s needed for the work to be done with no wasted energy.

Today, Sinamics Perfect Harmony is the world’s leading medium voltage drive, backed by a robust team of Industry Services. Each year, the drives help power more than 100 million homes – nearly all the homes in the U.S. And, the drives purify millions of gallons of drinking water in major cities across the U.S., keeping rivers, lakes and oceans clear and free from pollution.

Attendees for the event included State Representative Ryan Warner, Honorable Erin C Molchany (Southwest Director for Pennsylvania Governor Tom Wolf) and Honorable Anthony Costa, (Southwest Pennsylvania Director for Lt. Governor Mike Stack). Molchany addressed the assemblage with a message from Governor Wolf.
