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.

DESIGN OVERVIEW

This report aims to provide the user manual for the

development

board

SECO−MDK−4KW−65SPM31−

GEVB. 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
