The electronic speed controller (ESC) is an essential part of an electric propulsion system’s hardware. It acts like the brain of the system by telling the motor how fast to go based on data signals it receives from the throttle controller.
For smaller applications like drones and RC vehicles, this controller has the name ‘ESC’, whereas for larger manufacturing applications it may be called an electronic control unit, inverter, or motor controller. #drone #motorController #PCA9685 #controller #motor #esc #referenceDesign #project #EFM8BB21F16G #MPU9250 #template

So what is an ESC? Well, electronic speed controllers are used to control brushless motors, in thisc ase the motor has a triple phase input. To control this input, the ESC must apply a special sequence of LOWs and HIGHs signals in a predefined order. It has to conmutate very fast and by taht rotate the rotor of the motor. In this tutorial we will see how to control the rotation, the speed, detect the BEMF and by that know when to make the switch to the next step of the sequence. So this is a sensorless brushless motor speed controller since it uses no sensor to detect the rotor position. We will learn:
- The schematic and why we need each part
- Triple phase MOSFET bridge control
- BEMF detection and 0 cross
- Interrumprions and internal comparator of ATMEGA328
- PWM control

this is a half bridge MOSFET ESC for WYE wound BDLC. you connect VCC to common point (COM) of the BDLC. The three phase wires from the motor to Fase A, Fase B, Fase C. depending on which one of the MOSFETS is open (controlled via a microcontroller, connected to PB1, PB2, PB3), current passes through the respective coil of the motor, rotating it a bit.
