The system contains the latest advanced motion control IC, TM IRMCK203, and the ServoDesigner software. The complete B/Ms and schematics are provided so that the user can adapt and tailor the design per application needs. The system does not require any software code development due to the unique Motion Control Engine implemented in the IRMCK203 IC. Users can readily evaluate high performance Sensorless control without spending the development effort usually required in the traditional DSP or microcontroller based system. IRMCS2033 contains advanced iMOTION chipset such as IR2175 monolithic current sensing ICs and IRMCK203 full Sensorless Permanent Magnet motor drive, which enables simple and cost effective motion control design.
