iMOTION™ IMC100 is a family of highly integrated ICs for the control of variable speed drives. By integrating both the required hardware and software to perform control of a permanent magnet synchronous motor (PMSM) they provide the shortest time to market for any motor system at the lowest system and development cost. The integrated script engine allows to add application flexibility without interfering with the motor and PFC control algorithm.

iMOTION™ IMC100 is a series of highly integrated ICs for the control of a Permanent Magnet Synchronous Motor (PMSM). IMC101 devices provide control of a single motor while the IMC102 devices control the motor and additionally a boost or totem pole power factor correction (PFC).

The IMC100 series is based on Infineons Motion Control Engine (MCE) and integrate all hardware and software functions required to implement a closed loop sensorless or optionally sensor based control algorithm for permanent magnet motors. IMC100 devices do not require any software programming and can be configured for a wide range of motor control inverters.

The IMC100 series takes advantage of a new hardware platform that is based on a comprehensive set of innovative analog and motor control peripherals. The high level of integration both in terms of hardware modules and software algorithms results in a minimum number of external components required for the implementation of the inverter control.

Infineons patented and field proven Motion Control Engine (MCE) implements field oriented control (FOC) using single or leg shunt current feedback and uses space vector pulse width modulation (PWM) with sinusoidal signals to achieve highest energy efficiency. In addition to the motor control algorithm it also integrates multiple configurable protection features like over- and under-voltage, over current, rotor lock etc. to protect both the power stage as well as the motor during application tuning or in case of malfunction.

The second generation of the MCE further improves the performance of the sensorless control algorithm and adds functionality like optional sensor support for applications that require accurate rotor positioning, two types of ready-to-use PFC algorithms as well as more and flexible and faster host interface options.

The IMC100 series is offered in several device and package variants for applications from single motor control to motor control plus PFC. All devices can be used in applications requiring functional safety according to IEC 60335 (Class B).

There are multiple versions of the MCE software offered by Infineon and made available for download from the Infineon web site.

By using a special secure boot loader algorithm in combination with type specific chip IDs it is assured that these MCE software versions can only be installed onto the matching hardware derivatives, i.e. IMC100 variants for which the software has been tested and released for. Infineon as well as third parties provides tools to program these software images. For details please refer to the iMOTION™ programming manual.

The MCE integrates a script engine providing additional flexibility. The script engine can make use of analog and digital IOs for reading sensors or driving signals. The respective IOs are given in the pin lists referencing the name in the script to the physical pin of the package.
