100 W 3-phase inverter for BLDC sensorless motor
evaluation board
Introduction
The 100 W 3-phase inverter for the BLDC sensorless motor evalaluation board (for brevity
also referred with its order code STEVAL-IHM017V1) is a complete development platform
for BLDC sensorless motor application with nominal power up to 100 W. It is based on a
cost-effective, flexible and open design, including a three-phase inverter bridge based on
the STD5NK52ZD-1 Power MOSFET in IPAK package and an ST7MC 8-bit microcontroller
with 16 Kbyte internal Flash memory.
The system has been designed to drive a three-phase brushless motor with permanent
magnet rotor exploiting trapezoidal sensorless control.
The STEVAL-IHM017V1 features complete hardware for developing motor control
applications based on ST7MC peripherals including motor control peripheral (MTC). The
STEVAL-IHM017V1 uses an in-circuit communication (ICC) standard interface to connect to
the host PC via In-circuit debuggers/programmers such as the inDART-STX board from
Softec. The board is designed to support 230 Vac of bus voltage up to 100 W of input power.
It also includes a power supply stage with VIPer12A-E as the buck converter to generate
voltage reference for the driver and the microcontroller.

UM0522 System architecture
7/39
2 System architecture
A generic motor control system can be basically schematized as the arrangement of four
main blocks (see Figure 2):
●A control block whose main tasks are to accept user command and motor drive
configuration parameters and to provide digital signals to implement the proper motor
driving strategy
●A power block that makes a power conversion from DC bus transferring it into the motor
by means of a three-phase inverter topology
●The motor itself. The STEVAL-IHM017V1 board is able to drive a three-phase
brushless motor with permanent magnet rotor exploiting trapezoidal sensorless control.
●The power supply block is able to accept 230 Vac input voltage and provide the proper
levels to supply both the control block and power block devices.
Figure 2. Motor control system architecture
The system proposed by STEVAL-IHM017V1 includes all the above hardware blocks (apart
the motor) plus a software GUI that allows configuring the motor drive. Moreover, an open
source C code is available, derived from the ST7MC motor control libraries, allowing easy
customization and extension of control algorithms. The core of the control block is
constituted of an ST7MC MCU that provides the driving signals to the power block according
to a driving strategy, the latter one closely related to the motor type and characteristics.
Driving signals are constituted of 3 complementary PWM signals (in the range of 0-5 V) for
providing logic inputs for high/low side gate driver belonging to the power block. In the
system proposed, three legs are present (3-phase inverter). The power block, based on the
gate drivers L6386 and Power MOSFET (STD5NK52ZD-1), converts the control signals
from ST7MC MCU to power signals for the three phase inverter in order to drive the motor.
The board can be supplied by an AC power supply of 230Vac with a maximum input power
of 100 W. Please refer to Section 7: Board architecture on page 14 for more details on
system architecture.
With the included Power MOSFET device STD5NK52ZD-1, the maximum rating of rectified
voltage is 520 V and the maximum continuous current is 4.4 A at 25°C.

6 Board electrical characteristics
Stresses above the limit shown in Table 3 may cause permanent damage to the devices
present inside the board. 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. 15 V bias current measurement can be useful to check
the working status of the board. If measured value is considerably greater than typical value,
it means that some damage has occurred in the board. Supply the control board using a
15 V power supply connected to CON2 observing the polarity.

7 Board architecture
The STEVAL-IHM017V1 can be schematized as in Figure 4
Figure 4. Board architecture
The heart of the evaluation board is the ST7MC microcontroller with a dedicated peripheral
included to drive the three-phase brushless motor with permanent magnet rotor exploiting
trapezoidal sensorless control. The board is provided with three potentiometers (R61, R62,
R63) used for tuning, in real time, some parameters related to the drive. See Section 8:
Motor control operations on page 19.
Two LEDs (green/red) are used to get information about the status of the system. Their
behavior is related to the drive. See Section 8: Motor control operations on page 19.
In normal functionality it is expected that the board is supplied by VBUS connector J9 but an
auxiliary supply connector CON2 is included on the board to feed the drivers and the
microcontroller. This auxiliary supply can be useful for safety reasons, for example it should
be used to program or debug the device without feeding the board with high voltage.
One communication system can be established with the microcontroller:
●ICC used for programming/debugging purposes
7.1 Power supply
The power supply is able to address a wide range of AC input voltage voltages from 30 Vac
up to 270 Vac. The alternate current input is rectified by a diodes bridge and bulk capacitor
to generate a direct current bus voltage approximately equal to Vac minus the voltage
drop on the bridge and ripple.
Then we have used a VIPer12A-E based buck converter to generate voltage reference for
driver 15 V and a linear voltage regulator L7805 to generate the microcontroller voltage
reference (see Figure 5).

Figure 5. Power supply architecture
7.2 Power stage
The power stage is based on six power MOSFETs in full 3-phase bridge configuration. In
the board there are six STD5NK52ZD-1s in an IPAK package. Each device contains the
freewheeling Zener diode. Three L6386 have been used to drive the Power MOSFETs gates
and for hardware current protection. For each Power MOSFET in the 3-phase bridge the
network shown in Figure 6 (default configuration) has been used as the starting
configuration.
Figure 6. Gate driving network
In this default configuration the gate of the Power MOSFET is turned on by means of R1 and
D22 while the turnoff is performed very fast by means of the Q1 transistor. It is also possible
to use the alternate configuration of the network (See Figure 6). To set this configuration
transistor Q1, resistor R5 and C13 must be removed from each network (6). The direction of
the diode D22 must be inverted and a resistor R20 must be mounted. In this alternate
configuration the gate of the Power MOSFET is turned on by means of R1 and R20 while
the turnoff is performed by means of R1 and D22.

UM0522 Motor control operations

8 Motor control operations
8.1 Environmental considerations
Warning: The STEVAL-IHM015V1 evaluation board must only be used
in a power laboratory. The voltage used in the drive system
presents a shock hazard.
The kit is not electrically isolated from the DC input. This topology is very common in motor
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 communication 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 DC 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 switching
semiconductor devices such as MOFSETs.)
Note: Isolating the application rather than the oscilloscope is highly recommended in any case.
8.2 Hardware requirements
To set up the STEVAL-IHM017V1 evaluation board system, the following items are required:
●The board: STEVAL-IHM017V1
●High-voltage insulated AC power supply up to 230 Vac
●Softec inDART-STX (not included in the package)
●Softec ICC isolation board (not included in the package)
●Two 10-pin flat cables (not included in the package)
●3-phase brushless motor with permanet magnet rotor (not included in the package)
●Insulated oscilloscope (as needed)
●Insulated multimeter (as needed)

8.3 Software requirements
To customize, compile, and download the motor control firmware, the following software
must be installed:
●"STEVAL-IHM017V1 - GUI" (included in the CD-ROM)
●STVD7 for inDART-STX V.3.11 (also called "ST7 Toolset" downloadable from Softec's
website: www.softecmicro.com)
●Cosmic compiler - ST7 C compiler 16 Kbyte free version - 4.5c (downloadable from
Cosmic's website: www.cosmic-software.com).
8.3.1 Installing the software
STEVAL-IHM017V1 - GUI installation
Insert the CD-ROM provided with the kit and execute Setup.exe.
3rd party software installation
Follow the instructions of the related software to install and configure STVD7 for
inDARTSTX and cosmic compiler.
Installation note
1. Install the Cosmic compiler first. Use the default installation folder: "C:\Program
Files\COSMIC\CXST7_16Kbite". Registration is required before using the product. You
can perform this procedure at any time by running the "lmreg16k.exe" file inside
Cosmic's installation folder. Complete the form and click on the "Register by email"
button. You will receive a license file "license.lic" that must be copied inside the
installation folder under the "license" folder.
2. Then install STVD7 for inDART-STX. During the first run of the software after
installation, a prompt for the configuration of the toolset should appear. The toolset can
be configured at any time by opening "tools options" inside STVD7. To do this, click
"toolset", and select the "toolset" menu tab, select "ST7Cosmic" and configure as in
Figure 11.
