What are the principal advantages of a MagnaDrive ASD over a Variable Frequency Drive?
A. While Variable Frequency Drives, or VFDs, are energy efficient, their installation and use is not always practical or cost effective due to problems of reliability, complex electronic components, need for extensive infrastructure and highly trained personnel, speed range limits, electronic harmonics and maintenance demands. These problems are effectively eliminated by the simplicity of the MagnaDrive ASD. In general, existing VFDs are inefficient for high horsepower applications (90% of VFD applications have been for 20-HP or less) or medium/high voltage applications. The simple and reliable MagnaDrive ASD is ideally suited to pump, fan and blower applications, providing the energy savings of speed control without the problems often associated with VFDs. In these installations, system complexity is reduced, vibration is eliminated and alignment problems disappear. Motor systems can be resized for lower cost and more efficient operation. In addition, the MagnaDrive technology makes a
