Why use X-CUBE-MCSDK for your motor control application?
Spinning and controlling your electrical motor for your application isn't straightforward. We can help you...
The STM32 MC SDK provides a comprehensive solution for motor control applications.
From hardware to final motor control application
The process involves several key steps:
- Hardware setup: Use the ST-MC-SUITE online tool to identify the most appropriate hardware board.
- Motor characterization: Define electrical and mechanical models.
- Motor Control Workbench System configuration: Configure the system using STM32CubeMX & IDE.
- Project configuration and build: Utilize STM32CubeMX, STM32CubeIDE, or IAR/KEIL tools.
- Motor drive tuning: Use Motor Pilot for fine-tuning.
- Final application development: Implement user code, for example:
#include "MC.h" { CMCI OMCI = GetMCI(M1); MCI_ExecSpeedRamp(oMCI, final speed, ramp duration); MCI_StartMotor(oMCI); }
Transferring from ST hardware to custom hardware is easy
You can easily transfer your motor control solution from ST hardware to your custom hardware layout.
Hardware modification flow
The flow includes:
- Hardware modification
- Hardware board description
- Motor Control Workbench System configuration
- Project configuration and Project build (STM32CubeMX & IDE)
- Motor drive tuning (Motor Pilot)
- Final application development

FOC sensorless motor control algorithm status
Breakthrough FOC sensorless algorithm: high sensitivity observer
Version 6.1 and before: Standard STO Cordic and PLL algorithms available for PMSM motors.
Version 6.2 with HSO:
- Low speed performance
- Easier to tune (1 regulation loop only)
- Better performance at startup
- Reduced current consumption
New high sensitivity observer
Hardware impact:
- Voltage input + 2 ADC min
- Necessary for HSO algorithm
- 3 shunt configuration only
- STM32G4 only
Current consumption during startup procedure between STO PLL and HSO:
The HSO algorithm shows a lower current peak (16A) compared to STO PLL (23A).
HSO: increasing performance at low speed
Speed curves comparison STO PLL vs HSO control at 30% load:
- With STO PLL, control is lost below 70 rpm.
- With HSO, control is maintained at 20 rpm.
Key events:
- 1st speed command set to 60 rpm: STO PLL lost at this step.
- 2nd speed command set to 20 rpm: HSO still running until this step.
New ST low voltage low power hardware board
Available for best HSO performance:
- Power Board: B-DRIVE-LVLP01
- Control board: B-G473E-ZEST1S
Motor Control Connector V2: The STM32 B-ZEST-ADAPT1 adapter board allows connecting up to 3x power boards to the same control board.
STM32 support
The X-CUBE-MCSDK supports a wide range of STM32 microcontrollers:
STM32F0, STSPIN32F0, STM32F4, STM32L4, STM32F3, STM32G0, STM32G4, STSPIN32G4, STM32H7, STM32C0 (NEW), STM32H5 (NEW).
Dual motor application is back
Support for STM32F3, STM32F4, and STM32G4.
The MC Workbench allows configuration for dual motor applications, including power supply, drive settings, and motor parameters for each motor.
Support board customization
