iMOTION™ MADK starter kit for IMI111T IPMs

Introduction

1 Introduction
The EVAL-IMI111T starter kit provides an easy-to-use motor drive solution based on Infineon's IMI111T iMOTION™
IPMs. The board is equipped with all assembly groups for sensor-less field-oriented control (FOC). It contains a
single phase AC-connector, an EMI filter, a rectifier, and a 3-phase output for connecting the motor. The power
stage also contains source shunt for current sensing and a voltage divider for measuring the DC-link voltage.
Features of this board are described in Chapter 2 of this user guide. The other chapters provide information to
help users copy, modify, and qualify the design for production according to their specific requirements.
Environmental conditions were considered in the design of the EVAL-IMI111T. The design was tested as described
in this document but it is not qualified with regard to safety requirements or manufacturing and operating over
the whole operating temperature range or lifetime. The boards provided by Infineon are only subject to
functional testing.
Evaluation boards are not subject to the same procedures as regular products with regard to returned material
analysis (RMA), process change notification (PCN), and product discontinuation (PD). Evaluation boards are
intended to be used under laboratory conditions and only by trained specialists.
The iMOTION™ Motion Control Engine (MCE) integrated into IMI111T devices, together with the gate driver and
six IGBTs offers a complete motor drive system in a compact DSO22 surface mount package, minimizing the
external components count and PCB area.
