Industrial machinery spread throughout a plant floor runs on a variety of power sources, involving a number of intermediary steps to ensure maximum up time is retained. There are several power supply configurations that have made their way into the plant floor as the applications gain more diversity, i.e. from motors to sensitive electronic equipment.
There are many reasons why lead length between Variable Frequency Drives (VFDs) and motors are excessive. VFDs are sensitive electronic equipment and must be installed in clean and dry environments, forcing long distances between motor control rooms and the motors that they control. Also, some applications such as conveyors often use a single drive to operate multiple motors on the line. The length of the conveyor dictates the longest distance between drive and motor. With these constraints, output load reactors are the best answer in drive solutions to preventing motor failure.
