Description
IRMCO203 FPGA object code Sensorless permanent magnet motor (Sinusoidal Back EMF) control system, which downloaded into Xilinx Spartan2-300low cost FPGA. With IRMCO203, user readily build high performance Sensorless drive system without programming effort. This soft ASIC flexible that user configure optimize system specifically needs each application. With International Rectifier high voltage such IR2175 current sensing IR2137 3-phase gate drive IRMCO203 minimizes analog power electronics component count, simplifies design cost drives without shaft encoder. IRMCO203 easily adapted various permanent magnet motors through fully configurable (graphic user interface) tool.
