STM3210B-MCKIT and STR750-MCKIT
3-phase motor control power stage
Introduction
This manual describes the MB459B motor control evaluation board. The MB459B is an
AC/AC power converter that generates a three-phase waveform for driving three-phase
motors such as induction motors or PMSM motors.
It includes:
●
An input power stage with voltage rectification and auxiliary power supply,
●
A 7A three-phase inverter based on IGBT and level shifter,
●
A motor connector for linking with the control board,
●
A connector for motors with Hall/encoder and tachometer input.
The MB459B motor control evaluation board can be supplied in two ways:
●
From a single power supply for motors requiring a voltage greater than 18 V;
●
From a dual power supply for motors requiring a voltage less than 18 V.
This manual describes where the various components are located on the motor control
board, and the appropriate settings for driving a PMSM motor or an AC induction motor.
The MB459B board is delivered with the STM3210B-MCKIT and STR750-MCKIT motor
control kits. For more information on these kits, refer to www.st.com.

Power supply
The MB459B motor control evaluation board can be supplied from a single power supply or
from a dual power supply.
●
Single power supply for motors requiring a voltage greater than 18 V
The power is supplied to the J3 connector. The voltage must not exceed 42V DC or
30Veff AC. It supplies both the motor and the motor control board. A 15V DC voltage is
automatically generated for the motor control board logic. However, depending on the
voltage supplied, two cases are possible:
●
–
If the supplied voltage is greater than 35V DC, the W1 jumper must be set in
"HIGH VOLTAGE" position;
–
If the supplied voltage is between 18V and 35V DC, the W1 jumper must be set in
the "<35V ONLY" position.
Dual power supply for motors requiring a voltage less than 18 V
The power for the motor is supplied to the J3 connector, while a separate power supply
for the motor control board logic must be applied to the J1 connector (15V DC, 0.5 A).
Caution:
In the case of dual power supply, the W1 jumper must be removed and the D3 shortcircuit must be unsoldered (this is to avoid having reverse current in the linear
voltage regulator).
Note:
On the J3 connector, the polarity of DC input is not important.
Figure 2 shows where the power supply connectors are located on the board.

Operational amplifier configuration
Operational amplifier configuration
The MB459B motor control evaluation board can be configured to run in two current reading
configuration modes:
●
Three-shunt configuration
●
Single-shunt configuration
Single-shunt configuration requires a single op-amp, three-shunt configuration requires
three op-amps, and for compatibility purposes, one of them must be common to the two
configurations.
Jumpers W7, W8 and W9 allow you to set the common op-amp to achieve the compatibility
between single-shunt and three-shunt current reading mode.
The TSV994 used on the motor control board has a 20MHz gain bandwidth and operates
with a single positive supply.
Three-shunt current reading configuration
Figure 3 gives the op-amp configuration for the three-shunt current reading mode. In this
configuration, the alternating signal on the shunt resistor, with positive and negative values,
must be translated to be compatible with the single positive input voltage of the
microcontroller’s analog-to-digital converter used to read the current value.
This means that the op-amp must be polarized in order to obtain on the output a voltage that
makes it possible to measure the symmetrical alternating input signal.

Operational amplifier configuration
UM0379
The op-amp is used in follower mode with a gain set by resistors r and R.
G = s / v = (R + r)/r
The relation between the input signal e and the signal v on the positive input of the follower
is:
v = (U/(k*r3) + e/(k*r1))
where k =(1/r1+1/r2+1/r3)
The resistor values implemented on the MB549B board are:
R=5400Ω \ r=1000Ω \ r1=660Ω \ r2=560Ω \ r3=4700Ω
and
U=5V
Therefore, the gain is:
G = 6.4
The response of the op-amp is represented in Figure 4.

With these settings, the output voltage of the op-amp is equal to 1.94V for a nil current.
The peak current that can be measured in this configuration is:
+/- 5A for R_shunt = 0.1ohms
+/- 2.3A for R_shunt = 0.22 ohms

UM0379
Single-shunt current reading configuration
In the single-shunt current reading configuration, the current sampling is done only when the
value on the shunt resistor is positive.
The only positive value read on the shunt resistor allows to set a higher gain for the op-amp
than the one set in three-shunt mode. However, because the input of the op-amp is not railto-rail, in this configuration also, it is necessary to polarize the it to compensate for this
limitation.
Figure 5 shows the op-amp configuration used in single-shunt configuration.

The op-amp is used in follower mode with a gain set by resistors r and R.
G = s/v = (R + r)/r
The relation between the input signal e and the signal v on the positive input of the follower
is:
v = ((U*h)/(k*r4) + f(e))
with:
k =(1/r3+1/(r1+r2)+1/r4)
h=r1/ (r1 +r2)
f(e)=(e*r2)/ (r1 + r2) + (e*r1)/((k*(r1+r2)*(r1+r2))
The resistor values implemented on the MB549B board are:
R=11000Ω \ r=1000Ω \ r1=1130Ω \ r2=1000Ω \ r3=22Ω \ r4=2200Ω
and
U=5V
Therefore, the gain is:

Hardware settings for driving PMSM motors
Hardware settings for driving PMSM motors
To drive the PMSM motor, you must simply ensure that the MB459B motor control board is
driven by a control board that outputs the six signals required to drive the three-phase power
stage. The MB469B STR75x evaluation board provided in the STR750-MCKIT or the
STM3210B-EVAL evaluation board provided with the STM3210B-MCKIT are perfectly
suited for this task.
To drive any other generic high voltage PMSM motor, you must ensure that:
●
your PMSM motor is connected on the motor control board in place of the PMSM motor
provided, on the J5 and J8 connectors,
●
the motor phases are connected to the board on the J5 connector,
●
the encoder from the PMSM motor is connected to the board on the J8 connector
For example, for the Shinano PMSM motor provided with the STR750-MCKIT and the
STM3210B-MCKIT the connections are listed in Table 2.

Schematic diagrams
The MB459B motor control evaluation board schematics are split into two sheets:
●
Sheet 1/2 Current Measurement (Figure 8), shows the op-amp wiring and
configuration, the encoder/ Hall sensor adaptation, the tacho input stage and the motor
control connector wiring.
●
Sheet 2/2 Power Switch (Figure 9), shows the power converter with its associated level
shifter and all auxiliary power supplies.
The version of the board described in this manual is MB459-B01. The board version
information can be found on a sticker on the component side of the PCB (the visible one), on
the bottom left edge of the board when reading the serigraphy.
The changes on this version of the board compared with the previous version MB459-B00
are summarized below:
●
Operational amplifiers have changed, TSV994 replacing TSH24.
●
The value of capacitors C37, C42, and C47 has increased from 10pF to 100pF.
●
The value of resistors R13, R23 and R52 has decreased from 2.2kΩ to 1.8kΩ.
●
The D3 diode is now short-circuited.
●
The board can also be driven by the STM3210B-EVAL board.
