With more than 10,000 drives sold worldwide, SINAMICS PERFECT HARMONY variable speed drive has helped industries across the globe achieve greater reliability for their critical processes, even in the harshest operating environments. Our unique combination of industry experience, innovative engineering and full lifecycle support is what gives us our edge. Any variable speed drive can improve process control, but only Siemens medium voltage variable frequency drives offer 20+ years of built-in reliability, resulting in a lower total cost of ownership (TCO) over the lifetime of the drive.
In the sections below, you can read case studies about the industry-specific applications we’ve helped optimize, our white paper that compares TCO across various VFDs and our white paper that shows how VFDs can reduce your operating and maintenance costs.
Adding Reliability and Availability to Your Manufacturing Process
Learn how SINAMICS PERFECT HARMONY variable frequency drive (VFD) increases reliability while reducing total cost of ownership. Advanced Cell Bypass technology prevents operational disturbances in the event of a cell fault, and ProToPS™ informs operators before potential issues become serious problems.
Long Life Span
Learn more about which factors contribute to a drive’s TCO, how to calculate net present value (NVP), how Siemens drives achieve a low NPV — and more!
To Succeed, Control Your Speed
