IGBT Power module evaluation kit - ST7MC control board
Introduction
The ST7MC evaluation board STEVAL-IHM010V1 is a complete development platform for
STMicroelectronics' ST7MC microcontroller. Based on a cost effective, flexible and open
design, it allows easy demonstration of ST7MC capabilities and enables rapid evaluation of
the MTC microcontroller's peripherals. It includes the ST7MC 8-bit microcontroller with 16 K
internal Flash memory. The STEVAL-IHM010V1 features motor control Connector (MC-
Connector) and hardware features for developing motor control applications based on
ST7MC peripherals including motor control peripheral (MTC), Serial Communication
Interface (SCI). The STEVAL-IHM010V1 uses an In-Circuit Communication (ICC) standard
interface to connect to your host PC via In-Circuit Debuggers/Programmers like inDART-
STX board from Softec.

UM0430 System architecture
7/48
1 System architecture
The generic motor control system can be schematized as the arrangement of four blocks
(see Figure 2):
●Control block
●Power block
●Motor
●Power supply
Figure 2. Motor control system architecture
The system proposed for the IGBT power module eval kit is composed of one control board
STEVAL-IHM010V1, one power board STEVAL-IHM011V1, one motor and the power
supply.
The control board STEVAL-IHM010V1 is a microcontroller (ST7MC) based board that
provides the driving signals related to the motor selected and the driving strategies.
Driving signals are constituted of 6 PWM signals in the range of 0-5V paired in high side/low
side pairs of one pair for each leg. In the system proposed three legs are present (three-
phase inverter).
The power board STEVAL-IHM011V1 is based on the power module (STG3P2M10N60B)
that converts the control signal to power signals in order to drive the motor (see Power
Board User Manual for further details).
The connection between the control board and the power board is performed through
dedicated a 32-pin connector called “motor control connector” (see Section 5.1: MC
Connector).
The IGBT power module eval kit it is able to drive the following kinds of motors:
●AC induction motor, sensored
●Brushless permanent magnet motor (trapezoidal driven), sensored or sensorless
●Brushless permanent magnet motor (sinusoidal driven), sensored
The power board is supplied by a high voltage AC power supply 220 V (or 110 V) with the
capability to generate current up to 10 amps.

Safety and operating instructions UM0430
8/48
2 Safety and operating instructions
2.1 General
During assembly and operation, the IGBT power module eval kit poses several inherent
hazards, including bare wires, moving or rotating parts, and hot surfaces. There is danger of
serious personal injury and damage to property, if it is improperly used or installed
incorrectly.
All operations involving transportation, installation and use, as well as maintenance are to
be carried out by skilled technical personnel (national accident prevention rules must be
observed). For the purposes of these basic safety instructions, "skilled technical personnel"
are suitably qualified people who are familiar with the installation, use, and maintenance of
power electronic systems.
2.2 Reference design board intended use
The IGBT power module eval kit boards are components designed for demonstration
purposes only, and shall not be used for electrical installation or machinery. The technical
data as well as information concerning the power supply conditions shall be taken from the
documentation and strictly observed.
2.3 Reference design board installation
The installation and cooling of the reference design boards shall be in accordance with the
specifications and the targeted application (see Section 7: Motor control demonstration).
●The motor drive converters shall be protected against excessive strain. In particular, no
components are to be bent, or isolating distances altered during the course of
transportation or handling.
●No contact shall be made with other electronic components and contacts.
●The boards contain electrostatically sensitive components that are prone to damage
through improper use. Electrical components must not be mechanically damaged or
destroyed (to avoid potential health risks).
2.4 Electronic connection
Applicable national accident prevention rules must be followed when working on the main
power supply with a motor drive. The electrical installation shall be completed in accordance
with the appropriate requirements (e.g., cross-sectional areas of conductors, fusing, PE
connections. For further information see Section 7: Motor control demonstration.
2.5 Reference design board operation
A system architecture which supplies power to the IGBT power module eval kit boards shall
be equipped with additional control and protective devices in accordance with the applicable
safety requirements (e.g., compliance with technical equipment and accident prevention
rules).
