Brushless Motor - How they work BLDC ESC PWM
The Engineering Mindset・13 minutes read
Brushless motors use three-phase electricity to convert electrical energy into mechanical energy, eliminating brushes for increased efficiency. Outrunner motors, with the rotor outside, are popular for their higher torque and control is achieved by sending pulse width modulation signals to adjust speed.
Insights
- Brushless motors operate using three-phase electricity, converting it into mechanical energy efficiently due to the absence of brushes, which reduces friction.
- Outrunner motors, preferred for their higher torque, consist of a rotor with permanent magnets and a stator with wire coils grouped into three sets, requiring pulse width modulation signals for speed control.
