Comparing Two Types of Magnetically-Coupled Adjustable Speed Drives with Variable Frequency Drives in Pump and Fan Applications

Abstract

This paper presents the results from laboratory tests on MagnaDrive Corporation’s fixed magnet, magnetically-coupled adjustable speed drive and Coyote Electronics electromagnetic, magnetically-coupled adjustable speed drive, compared to a typical variable frequency drive (VFDs) for fan and pump loads. It also discusses advantages and disadvantages of using mechanical magnetically-coupled adjustable speed drives versus variable frequency drives, and it provides field experience with VFDs in food storage as well as adjustable speed drives in wastewater and other field applications.
