About this document
Scope and purpose
This user guide provides an overview of the EVAL-IMI111T evaluation board including its main features, key
technical data, pin assignments, and mechanical dimensions.
EVAL-IMI111T is a full featured starter kit that includes the IMI111T iMOTION™ IPMs. It provides a fully-integrated,
turnkey, high voltage motor drive solution designed for high performance and high efficiency permanent magnet
synchronous motor (PMSM)/
pumps, and compressors. EVAL-IMI111T also comprises other necessary circuitry required for out-of-the-box
evaluation of IMI111T iMOTION™ IPMs, such as rectifier and EMI filter stage, as well as an isolated debugger
section with USB connection to the PC.
The EVAL-IMI111T starter kit was developed to support customers during their first steps in designing
applications with IMI111T iMOTION™ IPMs.
The available variants of the IMI111T starter kit are listed in Table 1.
