SECO−MDK−4KW−65SPM31−GEVB www.onsemi.com Scope and Purpose This user guide provides practical guidelines for using and implementing a three−phase industrial motor driver with the Intelligent Power Module (IPM). The design was tested as described in this document but not qualified regarding safety requirements or manufacturing and operation over the entire operating temperature range or lifetime. The development board has been layout in a spacious manner so that it facilitates measurements and probing for the evaluation of the system and its components. The hardware is intended for functional testing under laboratory conditions and by trained specialists only. Hardware Revision – this user manual is compatible with version 1.0 SECO−MDK−4KW−65SPM31−GEVB. Attention: The SECO−MDK−4KW−65SPM31−GEVB is exposed to high voltage. Only trained personnel should manipulate and operate on the system. Ensure that all boards are properly connected before powering, and that power is off before disconnecting any boards. It is mandatory to read the Safety Precautions section before manipulating the board. Failure to comply with the described safety precautions may result in personal injury or death, or equipment damage. Prerequisites All downloadable files are available on the board website.

This development board (from here on MDK_SPM31) is a DC supplied three −phase motor drive inverter intended for industrial motion applications < 4 kW range. In this field, a trade−off between switching frequency and power management is the key to fulfil the requirements while providing a simple and robust solution. The system is compatible with three phase motors (BLDC, Induction, PMSM, Switched Reluctance etc.). The MDK_SPM31 power board is illustrated in Figures 2 and 3 (top and bottom view, respectively). The block diagram of the whole system is depicted in Figure 4. The foremost advantages that this development board brings are:
- System solution for industrial motor control applications
- Low component count with integrated IGBT power module
- Design fit for different motor technologies
- Friendly user experience with Graphical User Interface and selectable open loop/FOC closed loop control
- Rapid evaluation close to application condition
