Description

Description

The STEVAL-GMBL02V1 reference design kit is a complete triple motor field-oriented control (FOC) demonstration and evaluation platform. The kit is as an integrated environment for three axis Gimbal controller applications in the 6.0 V to 8.4 VDC bus voltage range (2 LiPo batteries), which you can increase up to 11 V with a maximum output current of 1.3 A for each motor drive.

The design features the STM32F303RE microcontroller with ARM® Cortex®-M4 32-bit core and the STSPIN233 low voltage three phase and three sense motor driver.

The STEVAL-GMBL02V1 is equipped with a USB interface for real-time data exchange. The kit includes an STEVAL-UKI001V1 ST-LINK adapter for serial wire debug (SWD) and corresponding cable. If you mount the STEVAL-UKI001V1 on the ST-LINK/V2-1 debugging section of an STM32 Nucleo-64 board, you can program and debug the STM32F303RE microcontroller with a compatible toolset via USB.

  • All features

    • Up to three-axis Gimbal controller.
    • Compact (50 x 50 mm) design, suitable for mounting on:
      • drones
      • handheld cameras
    • Three STSPIN233 low voltage three phase and three sense motor drivers.
    • STM32F303RE microcontroller with ARM® Cortex®-M4 core able to simultaneously drive three PMSM motors:
      • MCU runs a high efficiency field oriented control (FOC) algorithm compatible with the most common position sensors on Gimbal motors (PWM or analogic inputs)
      • compatible with open loop sensorless algorithm
    • Operating voltage from 6.0 V to 8.4 V (2 LiPo batteries).
      • maximum output current 1.3 ARMS.
    • Protection mechanisms:
      • triple single shunt current sensing network
      • non-dissipative overcurrent protection
      • short-circuit protection
      • thermal shutdown
      • hardware overvoltage and polarity inversion protection
    • Measurement units:

    • Interfaces:
      • STEVAL-UKI001V1 Serial Wire Debug (SWD) board with cable
      • USB connector for real-time data communication
      • three connectors for Pitch, Roll and Tilt axis target angle inputs (PWM mode)
      • one channel DAC output and one GPIO test point for debugging purpose
    • 2 Kbit serial I²C bus EEPROM for data storage
    • WEEE and RoHS compliant
