Battery eliminator circuit (BEC): 5 V/0.5 A for external receiver or FCU • Example project available on STM32 motor control software development kit (X-CUBE-MCSDK) • Supported by ST motor control software SDK and ST motor profiler • Compact PCB design: 29.1 x 58 mm •... -
Page 4: Description
The same 6Step (or trapezoidal) control algorithm (often with no shunt resistors) drives the many different ESCs offering various motor current, size and input voltages for remote control applications. A more sophisticated control algorithm is used in the STEVAL-ESC001V1, based on field oriented control (FOC); it features: •... -
