Pierce Verleur of Industrial Drives


Development of Matrix VFD technology for Industrial Applications

From the beginning, Variable Frequency Drives (VFDs) was have been used to control the speed of electric motors, which consume approximately 25% of the world’s electrical energy in industrial and commercial applications. By definition, a VFD enable a user to operate a motor at any commanded speed, as opposed to running across-the-line at a fixed speed. This variable speed control saves significant energy and also lessens the wear and tear on mechanical couplings, such as gears, belts and pulleys. Conventional VFDs introduce harmonic content which can cause cables to overheat, circuit breakers to trip, and cause stress on upstream transformers. On the other hand, Matrix VFDs provide ultra-low harmonics and near-unity power factor. The Matrix design also provides energy savings through regeneration. When a motor is being driven by a load, as opposed to driving the load, it acts as a generator, sending voltage back to the VFD. The presentation will focus on the evolution of Matrix VFD technology in the industrial sector. 


Mr. Verleur received a Bachelor's degree in Mathematics and an MBA. He began his career as a staff engineer for Carpenter Steel Corp. He co-founded two companies, IDD in 1984 and Rosa Automation Engineering in 1990. Rosa was merged with EMS in 1995 and ultimately acquired by Magnetek in 1999. Pierce held the position of Western Regional Manager for EMS from 1995 - 1999. Mr. Verleur's experience with AC and DC drives began in 1980. He has worked extensively with motor and motion control since then, developing several new products as well as new solutions to traditional motor control applications. Mr. Verleur is now concentrating his experience in the role of Outside Sales Engineer for IDD.
