Description
IRMCK203 is a high performance digital motion control IC for Sensorless AC permanent magnet motor application. Control is
based on closed loop vector control for sinusoidal Back EMF motors. With IRMCK203, the users can readily build a high
performance Sensorless drive system without any programming effort and minimum start-up time. Built-in unique start-up and
ramping algorithm enables wide application. This IC is versatile enough that the users can configure and optimize system
performance according to the needs of each application. With International Rectifier iMOTION products including high voltage
ICs such as IR2175 current sensing IC and IRAM series of Intelligent IGBT module in combination with IRMCK203, the end
result is a fully optimized system with reduced electronics component counts. This simplifies the design for low cost Sensorless
drive modules. IRMCK203 can be easily adapted to various permanent magnet motors through ServoDesigner
TM
tool, which is
the fully configurable graphic user interface tool.
