IRMCS2031
Overview
The IRMCS2031 is a design platform for a complete Sensorless drive system based on the IRMCK201 digital motion
control IC. The system is based on configurable control engine implemented by hardware logics in the IRMCK203.
The system has a simple and low cost structure, made possible by an advanced IR motion components including the
IRAMX16UP60A IGBT module, and IR2175 monolithic current sensing high voltage IC. These components together
with the IRMCK203 simplify hardware implementation. Since all control logic is implemented in hardware logic as
opposed to programmed software, unmatched parallel computation is achieved resulting in higher bandwidth control
and higher motor operating frequency (15 usec minimum PWM loop cycle).
Despite of hardware logic implementation, its design flexibility allows the user to configure Permanent Magnetic ac
motors (Sinusoidal Back EMF) with different motor parameters and different types of communication protocols.
