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.

4 Control board electrical characteristics
Stresses above the limit shown in Tabl e 2 may cause permanent damage to the device. This
is a stress rating only and functional operation of the device under these conditions is not
implied. Exposure to maximum rating conditions for extended periods may affect device
reliability.
5 V Bias current measurement can be useful to check the working status of the board. If the
measured value is considerably greater than the typical value, it means that some damage
has occurred in the board.

5 Board architecture
The STEVAL-IHM010V1 can be schematized as in Figure 3.
Figure 3. Control board architecture
The heart of the control board is the ST7MC microcontroller which is provided with a
dedicated peripheral to drive the three-phase brushless motor.
The user interface is constituted of four potentiometers (P1, P2, P3, P4) which are used to
set parameters related to the specific drive, see Section 7: Motor control demonstration.
Two push buttons are also present:
●Reset button for a "hardware reset" of the board.
●Start/stop button used to start and stop motor driving, see Section 7: Motor control
demonstration.
Two LEDs (green and red) provide information about the status of the system. Their
behavior is related to the specific drive, see Section 7: Motor control demonstration.
In normal functionality it is expected that the board is supplied by the MC connector, but for
stand-alone operation, an auxiliary supply connector for 5 V power supply is included on the
board. Providing more than 5.5 V through this connector may cause permanent damage to
the device since no over voltage protection device is present.
The board is supplied with 2 Kbit EEPROM (M95020) connected to the micro by an SPI bus.
To enable the onboard EEPROM memory, the jumper J2 must be closed and the debug
feature must be disabled inside the firmware.
J5 can be set by the user by connecting a jumper between pins 1-2 or 2-3. This setting is
related to a specific drive, see Section 7: Motor control demonstration.

Two communication systems can be established with the microcontroller:
– ICC Used for programming/debugging purposes
– SCI Used for data exchange through SDI connector
The control board is connected to the power board through a specific connector (MC
Connector).

5.1 MC Connector
The 34-pin MC connector has been designed as the standard to connect the control board
to the power board. Following the configuration of the MC connector it is possible to design
a different control board or power board preserving the compatibility between the two
systems. For instance it is possible for any user to redesign the control board keeping the
compatibility with the power board if the standard MC connector configuration is used.

5.3 Serial Data Interface (SDI)
The board is provided with a serial data interface (SDI) able to establish SCI communication
with an external device. We suggest using an isolation board between the SDI and the
external devices. The pin out is shown in Figure 7.

7.1 Environmental considerations
Warning: The IGBT Power Module Eval Kit must only be used in a
power laboratory. The high voltage used in any HV drive
system presents a serious shock hazard.
The kit is not electrically isolated from the AC input. This topology is very common in AC
drives. The microprocessor is grounded by the integrated Ground of the DC bus. The
microprocessor and associated circuitry are hot and MUST be isolated from user controls
and serial interfaces.
Warning: Any measurement equipment must be isolated from the main
power supply before powering up the motor drive. To use an
oscilloscope with the kit, it is safer to isolate the AC supply
AND the oscilloscope. This prevents a shock occurring as a
result of touching any SINGLE point in the circuit, but does
NOT prevent shocks when touching TWO or MORE points in
the circuit.
An isolated AC power supply can be constructed using an isolation transformer and a
variable transformer. A schematic of this AC power supply is in the application note, "AN438,
TRIAC + Microcontroller: safety precautions for development tools." (Although this
application note was written for TRIAC, the isolation constraints still apply for fast switching
semiconductor devices such as IGBTs).
Note: Isolating the application rather than the oscilloscope is highly recommended in any case.
