Drone Electronic Speed ​​Controller Reference Design

The STEVAL-ESC001V1 lets you spin a motor and its propeller in minutes thanks to a complete pre-configured firmware package (STSW-ESC001V1), implementing a sensorless Field Oriented Controlled algorithm with 3-shunt current reading, speed control and full active braking.
The reference design board can accept commands from a flight control unit through PWM signals; other communication bus interfaces like UART, CAN, and I²C are also available.
The reference embeds a battery eliminator circuit working at 5 V, an NTC sensor for temperature measurement and circuitry for overcurrent / overvoltage protection (OCP/OVP).
The compact form factor and current capability render this reference design suitable for electronic speed controllers on small and light unmanned aerial vehicles like professional drones.
The STSW-ESC001V1 firmware/software package plus STM32 PMSM FOC software development kit - MC library let you refine your electronic speed controller design by acting on the field oriented control parameters embedded in the STM32 and experiment with the ST motor profiler to rapidly retrieve the motor parameters. The ST sensorless FOC algorithm ensures longer flight times and optimal dynamic performance.
The STEVAL-ESC001V1 has been designed around the highly efficient, low R_dson STripFET F7 power MOSFETs, the high-performance STM32F303CBT7 microcontroller with ARM^® Cortex^®-M4 core and the L6398 drivers.
