IntroductionThe X-NUCLEO-IHM17M1 is a low voltage three-phase brushless DC motor driver expansion board based on STSPIN233 forSTM32 Nucleo. It is an affordable and easy-to-use solution with motor driver operation in low voltage battery scenarios, allowingzero consumption state (such as in thermal printers, robotics, toys, etc..).

The X-NUCLEO-IHM17M1 supports the addition of other boards to a single STM32 Nucleo board through the Arduino UNO R3and the ST morpho connectors.

Furthermore, the board is designed for six-step and FOC algorithms.

4 Circuit description

The STSPIN233 integrates a protected triple half-bridge with low RDS(on) for evaluating a solution for a three-phase BLDC motor in very low consumption mode.The device is protected against overload and short-circuits: short to ground, short to motor supply voltage, shortbetween the outputs. If one of the failure events occurs, the fault signal is set and the fault LED D10 is lit (red).The STSPIN233 is compatible with single and three-shunt sensing, and the X-NUCLEO-IHM17M1 expansionboard is designed to provide both topologies. The current feedback signal conditioning is performed by hardwareavailable on the board and sent to the STM32 Nucleo board through the ST morpho connectors.Motor speed regulation can be performed by hardware, by acting on trimmer R36. In this way, you can change thereference used by STM32 firmware for speed regulation.The X-NUCLEO-IHM17M1 expansion board provides two hardware solutions for motor position feedback: onebased on sensors and the other one based on sensorless detection.

4.1 Hall/encoder motor speed sensorThe X-NUCLEO-IHM17M1 expansion board implements the Hall/encoder sensor detection circuit for motor speedfeedback. The motor sensor feedback is connected through the J4 connector and an analog circuit to the STM32Nucleo board in order to detect the motor rotation.For sensors requiring external pull-up, three 10 kΩ resistors are already mounted and connected to the VDDvoltage (if these are not necessary, you can remove them).

4.2 Sensorless detectionIn six-step driving mode, one of the three phases is left in high impedance state: comparing this phase voltagewith the center-tap voltage, we can detect the BEMF zero-crossing.This signal is acquired through an analog circuit embedded on the expansion board and sent to the STM32Nucleo board through the ST morpho connectors.

4.3 Bus voltage circuitThe X-NUCLEO-IHM17M1 expansion board provides the hardware bus voltage sensing. This signal is acquiredwith a resistor divider from the motor supply voltage (VBUS) and sent to the analog to digital converter.
