UM2278 STEVAL-SPIN3202 Evaluation Board

Getting started with the STEVAL-SPIN3202 evaluation board, advanced BLDC controller with embedded STM32 MCU

Introduction

The STEVAL-SPIN3202 three-phase brushless DC motor driver board is based on the STSPIN32F0A 3-phase controller with integrated STM32 MCU and STD140N6F7 MOSFETs.
It implements a single shunt resistor current reading topology and provides an easy-to-use solution for the implementation of home appliances, fans, drones, power tools, and low voltage motor driving applications. The board is designed for censored or sensor less vector control FOC and six-step algorithms with single shunt sensing.

Hardware and software requirements

Using the STEVAL-SPIN3202 evaluation board requires the following software and hardware:

• a Windows ® PC (XP, Vista 7, Windows 8, Windows 10 ) to install the software package;
• a mini-B USB cable to connect the STEVAL-SPIN3202 evaluation board to the PC;
• a firmware package based on the STM32 Motor Control SDK (X-CUBE-MCSDK-Y);
• a 3-phase brushless DC motor with compatible voltage and current ratings;
• an external DC power supply.

Getting started

To use the board:

1. Check the jumper position according to the target configuration (see Section 2.2.1 Six-step/FOC selection)
2. Connect the motor to J3 connector taking care of the motor phases sequence
3. Supply the board via J2 connector input 1 and 2; the DL1 (red) LED turns on
4. Connect the board to the PC through the USB cable
5. Develop your application using the STM32 Motor Control SDK X-CUBE-MCSDK-Y.

Note:
The board maximum ratings are:

• power stage supply voltage (VS) from 6.7 V to 45 V;
• motor phase current up to 15 Arms.

Circuit description

• The STEVAL-SPIN3202 evaluation board provides a complete single-shunt six-step solution consisting of an STSPIN32F0A advanced BLDC controller with an embedded STM32 MCU and a triple half-bridge power stage with the STD140N6F7 NMOS.
• The STSPIN32F0A autonomously generates all the required supply voltages starting from the motor supply: the internal DC/DC buck converter provides 3.3 V and the internal linear regulator provides 12 V for the gate drivers.
• The current feedback signal conditioning is performed through the operational amplifiers embedded in the device and an internal comparator performs overcurrent protection via the shunt resistor.
• Two user buttons, two LEDs and a trimmer are available to implement simple user interfaces (e.g., starting/stopping the motor and set target speed).
• The STEVAL-SPIN3202 evaluation board supports the quadrature encoder and digital Hall sensors for motor position feedback. It also provides the circuitry to sense the motor BEMF (sensor less operation).
• The board includes an ST-LINK/V2 which allows the user to debug and download firmware without additional hardware.
• The board also supports censored or sensor less field oriented control algorithm with single-shunt sensing.

Six-step/FOC selection
The user can select between six-step and field oriented control modes by selecting different jumpers on the STEVAL-SPIN3202 evaluation board.

The FOC mode is selected as per the following configuration:

• jumper connected on J12 open and jumper J11 closed;
• jumper connected on JP8 between pin 2 and 3 (FOC position). The six-step mode is selected as follows:
• jumper connected on J12 closed and remove jumper from J11;
• jumper connected on JP8 between pin 1 and 2 (six-step position).

Hall/encoder motor speed sensor

• The STEVAL-SPIN3202 evaluation board supports the digital Hall and quadrature encoder sensors as motor position feedback.
• The sensors can be connected to the STSPIN32F0A by closing jumpers JP5, JP6 and JP7 (open by default).
• Note: When JP5, JP6 and JP7 are closed (Hall/encoder mode), JP9, JP10 and JP11should be respectively open (BEMF sensing mode).
• The Hall sensor/encoder should be connected to J4 as per the following table.

Table 3. Hall/encoder connector (J4)

A protection resistor of 1 kΩ is mounted in series with the sensor outputs.
For sensors requiring an external pull-up, three 10 kΩ resistors are already mounted on the output lines and connected to the VDD voltage. On the same lines, a footprint for pull-down resistors is also available.

JP3 jumper selects the power supply for the sensor supply voltage:

• jumper between pin 1 and pin 2: Hall sensors powered by VUSB (5 V)
• jumper between pin 1 and pin 2: Hall sensors powered by VDD (3.3 V)

Overcurrent detection and current sensing measurement

• The STEVAL-SPIN3202 evaluation board implements overcurrent protection based on the STSPIN32F0A integrated OC comparator.
• The shunt resistor measures the load current. R26 and R27 resistors bring the voltage signal to the OC_COMP pin. When the peak current flowing though the shunt exceeds the selected threshold, the integrated comparator is triggered and all the high side power switches are disabled.
• The current threshold of the STEVAL-SPIN3202 varies according to the STSPIN32F0A OC threshold as listed in the following table.

Table 4. Overcurrent thresholds

Bus voltage sensing circuit
The STEVAL-SPIN3202 evaluation board provides the bus voltage sensing. This signal is set through a voltage divider by the motor supply voltage (VBUS, R10 and R16) and sent to the PB1 GPIO (the ADC channel 9) of the embedded MCU. The signal is also available on TP6.

Hardware user interface
The board provides the following hardware user interface:

• potentiometer (R6 setting, for example, the target speed)
• switch SW1 (to reset STSPIN32F0A MCU and ST-LINK/V2)
• switch SW2 (user button 1)
• Switch SW3 (user button 2)
• LED DL3 (user LED 1, turned on when the user 1 button is pressed too)
• LED DL4 (user LED 2, turned on when the user 2 button is pressed too)

Debug
The STEVAL-SPIN3202 evaluation board embeds an ST-LINK/V2 debugger/programmer.

The ST-LINK/V2 features:

• USB software re-enumeration
• virtual com port interface on USB connected to the STSPIN32F0A (UART1) PB6/PB7 pins
• mass storage interface on USB

The ST-LINK/V2 is supplied by the host PC through the USB cable connected to the board.
LD1 LED signals ST-LINK/V2 communication status:

• Red LED flashing slowly: at power-on before USB initialization
• Red LED flashing quickly: following the first successful communication between the PC and ST-LINK/V2 (enumeration)
• Red LED ON: the initialization between the PC and ST-LINK/V2 is complete
• Green LED ON: successful target communication initialization
• Red/green LED flashing: during communication with target
• Green ON: communication successfully completed

The reset function is activated by removing J8 jumper.
