Given the growing prevalence of the Siemens Robicon Perfect Harmony in critical applications, it was only a matter of time before it reached 10,000 drives sold globally and an installed base of 2.2 million KW. It hit the milestone last week, just shy of 20 years since its launch in 1994. Over the past couple of decades, the Siemens Robicon Perfect Harmony medium voltage variable frequency drive has helped manufacturers in a wide range of industries — from oil and gas to power generation — achieve the reliability their critical processes require. Today it is the world’s No. 1 selling drive. The Siemens Robicon Perfect Harmony drive draws on extensive experience with a wide range of industry applications — including more than 80 types of pumps, 34 types of fans, and a dozen different compressors — to deliver the greatest reliability possible. Virtually any motor can be paired or retrofit with a Siemens Robicon Perfect Harmony drive to provide optimal versatility, efficiency and process availability for critical applications. Its modularity and 50+ patented technologies allow for a scalable solution that achieves 99.99% availability, which means greater productivity and a significantly reduced total cost of ownership over the drive’s lifecycle. And only Siemens Robicon Perfect Harmony drives feature Advanced Cell Bypass, a reliability failsafe that allows the drive to bypass faulted cells while maintaining a balanced output voltage at all times. These features contribute to the impressive 200,000-hour MTBF that drives Siemens Robicon Perfect Harmony global sales. Siemens is announcing the landmark achievement in advance of the drive’s upcoming name change. Effective Jan. 1, 2014, the Siemens Robicon Perfect Harmony drive joined the Siemens Sinamics family of drives and was renamed the Sinamics Perfect Harmony drive. Sinamics is the industry’s most comprehensive drive family, and the addition of Siemens Robicon Perfect Harmony will only serve to further broaden its offering of high-performance integrated drive solutions.
