Did you know Dynamatic sells VFDs too?

While Dynamatic is the world’s premier manufacturer of Eddy Current Drives, there are applications that require the use of a VFD. Being variable speed experts, we believe we need to serve as many markets as we can, irrespective of the technology used. Our real strength is in knowing the applications and the pitfalls associated with each application as well as the strengths and weaknesses of each. We encourage variable speed customers to reach out to us and let us serve their variable speed needs.
