iMOTION? IMC100 is a series of highly integrated ICs for the control of variable speed drives. By integrating both the required hardware and algorithm 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.

Infineon’s patented and field-proven Motion Control Engine (MCE) implements Field Oriented Control (FOC) using single or leg shunt current feedback and uses space vector PWM with sinusoidal signals to achieve highest energy efficiency. It also integrates multiple protection features like over- and undervoltage, overcurrent, rotor lock etc. Powerful tools like MCEWizard and MCEDesigner reduce the implementation effort for a variable speed drive to a simple configuration of the MCE for the respective motor.

The IMC100 series takes advantage of a new hardware platform that brings a comprehensive set of innovative analog and motor control peripherals.

The next generation of the MCE not only further improves the performance of the control algorithm but also adds functionality like sensor support for accurate rotor positioning, ready-to-use PFC algorithms as well as more and faster host interface options.

The IMC100 series is offered in several device variants ranging from single motor control to motor control plus PFC. All devices can be used in applications requiring functional safety acc. to IEC 60335 (‘Class B’). With this wide application scope the IMC100 series is the perfect choice for any highly efficient variable speed drive.

評估板EVAL-M1-101T

EVAL-M1-101T is an evaluation-board as part of the iMOTION? Modular Application Design Kit. This board features and demonstrates Infineon’s Advanced Motion Control Engine (MCE 2.0) technology for permanent magnet motors drive over the full speed range.

The evaluation board EVAL-M1-101T was developed to support customers during their first steps designing applications with running any permanent magnet motor via sensorless sinusoidal control.

The EVAL-M1-101T evaluation board is a part of the iMOTION? Modular Application Design Kit for drives (iMOTION? MADK). In order to run a motor, the mating power board is required to interface this evaluation board.

The MADK platform is intended to use various power stages with different control boards. These boards can easily be interfaced through the 20-pin iMOTION? MADK M1, or the 30-pin iMOTION? MADK M3 interface connector. This board is equipped with 20-pin M1 connector and is intended for single motor control only.

This evaluation board is designed to give comprehensible solutions of sensorless control of permanent magnet motors over the full speed range. It provides a capable of 3-phase and type 3 of 2-phase modulation, a micro- USB connector and on board debugger isolated by digital isolator, and UART interface.
