how many Motors are used in drone
Answers
Answer:
For beginners there are 2 types of motors used in drones: brushed and brushless motors. They vary in the way they work. The brushless is way more powerful for their weight than brushed motors, and they last way longer. For bigger quads: no question, brushless is king.
But for the micro and nano drones, it's fantastic to have these cheap motors to crash with confidence.
The internal workings of a brushed and a brushless motor is the same; both are based on electromagnetism.
When the motor windings become energized (both the motors have coils), a temporary magnetic field is created that repels (and/or attracts) against the permanent magnets present inside the motor.
This magnetic force is creating the repulsive force in the coil that is used to spin/rotate the shaft.
Efficiency wise, brushless motors are typically 85-90% efficient whereas a brushed DC motor is 75-80%. Windings are present on the rotor for a brushed motor as compared to in a stator for a brushless motor
This difference in efficiency means that more of the total power used by the motor is being turned into rotational force and less power is being lost as heat.
Brushless motor lasts longer because there are no brushes to wear out, while the brushed motor wears out quickly. That's one of the reasons brushed motors came out cheaper then brushless motors.
This guide is mostly oriented on brushless motors used in racing/freestyle fpv drone configurations.
