ST’s demonstration board controls two three-phase brushless motors using an onboard STSPIN32G4 controller with an embedded MCU. The controller’s integrated MCU is based on a 32-bit Arm Cortex-M4 core, ...
What is a brushless ESC, really? Well, generally, it’s usually a microcontroller with a whole lot of power transistors hanging off it to drive three phases of brushless motor coils. [Frank Zhao] ...
