The article covers:

  • How ESCs track the motor’s real-time position and speed
  • Other functionality provided by Advanced Power Drives’ ESCs, such as quick reversals of the motor, regenerative braking, and telemetry
  • Protection mechanisms such as over-current, over-voltage, over-temperature and desynchronisation protection
  • The difference between bus current and phase current
  • How motor speed, input voltage and PWM (pulse width modulation) are linked
  • How ESCs are rated
