iMOTION™ ICs integrate all the control and analog interface functions required for sensor less field oriented control (FOC) of PM motors using DC link or leg shunt current measurements. In addition they feature Infineon’s patented and field proven motor control engine (MCE) that eliminates software coding from the motor control algorithm development process. Implementing a variable speed drive is reduced to configuring the MCE for the respective motor. Assisted by powerful tools like MCEwizard and MCEDesigner it is possible to have the motor up and running in less than an hour.
iMOTION™ IMM100 is a series of fully integrated Smart IPMs implementing sensorless Field Oriented Control (FOC) of a Permanent Magnet Synchronous Motor (PMSM). The combination of the iMOTION™ Motion Control Engine (“T”- variants) with the gate driver and six MOSFETs offers a complete motor drive system in a compact 12 x 12 mm2 surface mount package, minimizing external components count and PCB area.
