Siemens' Micro Master Vector and Midi Master Vector Variable Frequency Drives (VFDs) are reportedly the first to integrate sensorless vector control into the small dimensions of a standard frequency controller. The two units are smaller in size and offer more standard features than their VFD predecessors. They are also compatible with standard induction motors ranging between 1/6 to 100 hp. Introduced in 1993, the Micro/Midi Master drives were among the first VFDs to offer breakthrough technologies, such as flux current control for automatic current load adaption. In their latest iteration, the controllers' sensorless vector inverter capability derives from a new ASIC that quickly calculates rotor speed and position. This enables the rotor and stator current to be controlled for optimized performance. Siemens Energy & Automation Inc. Product Code 4362 (P)
