Welcome again! In this post we will discuss about the main part of the whole Quadcopter/Multirotors system. Here we will learn about What is Motor? Types of Motors|Brushed & Brushless motor. Before knowing about Motors, Types of Motors you must know the basics of Quadcopters or UAV or Multirotors. As we are discussing about Brushed & Brushless motors so we must know about the system on which we want to implement it.

What is Motor?
An electric Motors is an electric machine that converts electrical energy into mechanical energy. Whereas the reverse mechanism i.e conversion of mechanical energy into electrical energy can be done with the help of electric generator. The electric motors can be powered up by direct current sources like battery or from generators, invertors which are alternating current sources.
Motors are of two types:
- Brushed motors
- Brushless motors
A brushed DC engine is an inside commutated electric engine which is intended to be keep running from an immediate current force source. A Brush DC Motors gives accuracy control of rate, which is driven by an immediate current. For especially high proportion of torque to dormancy, the Brush DC Motors can normally supply three to four times more torque than it’s evaluated torque. If it needs five times more torque, it can even give up to five times more, without slowing down. Brushed DC engines can be differed in rate by changing the working voltage or by changing the quality of the attractive field. The properties of the engine are mostly dependent upon the material it is made up of, the quantity of curls twisted around it, and the thickness of the loops. The armature or rotor is an electromagnet, and the field magnet is a perpetual magnet.
Whereas, Brushless electric engine which are mostly called electronically commutated engines, these are synchronous engines which are fueled by a DC electric source by means of a generator, inverter/exchanging power supply. The brushed D.C engine ought to never be utilized for operations that request long life and dependability. Therefore, brushless engines are utilized as a part of the greater part of the present day gadgets. Proficiency of a Brushless engine is ordinarily around 85-90%, though the routine brushed engines are just 75-80% proficient. Since the rotor is the sole conveyor of the magnets, it requires no force, i.e., no associations, no commutator, and no brushes. Set up of these, the engine utilizes control hardware.
