Advanced Power Drives has released an article that explains the main features of electronic speed controllers (ESCs) for brushless DC (BLDC) motors and how they work. ESCs are used by drone flight controllers to control and adjust the speed of the UAV’s electric motors.

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
