Electric motors are used in many tools and vehicles. In drones and electric aircraft, they are most often controlled with a throttle controller and ESC.
When you increase the throttle on your controller, what you are doing is increasing the amount of electrical power drawn from your power supply (i.e. battery) and fed to your motor via the ESC. If you want to slow down the motor, reduce power; If you want to speed up the motor, crank up the power.
But what is the mechanism behind controlling the motor’s speed?
In this article we cover:
- How to increase (or decrease) electric motor speed
- Motor speed in terms of PWM duty cycle and ESC output voltage
- The Motor KV to RPM calculation
