Welcome again!!! Today we will discuss about the main part of the whole Quadcopter/Multirotors system. Here we will learn about Selection of brushless motors for Quadcopter. Before knowing about the motors like Cobra Motor, Tiger Motor etc. you must know the basics of Quadcopters or UAV or Multirotors. As we are discussing about Selection of brushless motors for Quadcopter so we must know the about the system on which we want to implement it.
Selection of brushless motors for Quadcopter | Cobra Motor, Tiger Motor
Selection of best motors is the main part for designing a quadcopter/multirotor there are various KVs motors are available in the market. But before go further we should have to know about the various parameters that are very important for the selection of motors like KV value, recommended cells 3S or 4s or else battery, how much thrust we actually needed, efficiency etc. Here we’ll discuss about various motors some of them are Dragonfly 2206, 2800 KV motors, cobra motors 2204, 1960, 2300, 2206 KV motors, FLV MC2206, 2000 KV Brushless Motors etc.
1000 KV motor powered by an 11.1 volt battery would spin at,
1000 * 11.1 = 11,100 RPM with no load.
Lets discuss about the types of motors and compare them:
Dragonfly 2206 2800KV Motors
These motors are used to design the mini quadcopter and their rpm is depends on its KV values like the above given is much higher than other simple brushless motors because of that these motors are quite expensive and more powerful on comparison with other motors. If you want to know about various 3S or 4S batteries then know about What is Battery? How do batteries work? Types of Batteries .The higher KV and electrical rating allows these motors to deliver higher thrust as compared to other motors.
Cobra motors 2204, 1960, 2300, 2206 KV motors
Currently there are many motors are available in market for mini quads, one of these motors is mainly use with the high KV values, That is Cobra Motors. There are four type of models which are available for cobra motors in the market that are mainly use to fly high the mini quads are:
- 2204 1960 KV
- 2204 2300 KV
- 2206 2100 KV
- 2208 2000 KV
The first four digits of the motor number represents the dimension, Stator Diameter and stator thickness (generally how tall, and how thick). The other Four Digits Represents the change in rotation speed of the motor per change in the voltage of the battery connected.
FLV MC2206, 2000KV Brushless Motors
These motors are too power full and expensive too. That 2206 class motors are designed for Mini quads. If you are looking for high speed motor than other, then these are perfect for your mini quad. If you have 3S batteries then you need that batteries two in numbers or 1*4S battery. If you want to test motors RPM there are various method to do that like Hall Effect sensor method etc. With 5030 Propellers on 4S it’ll providing 570 grams thrust at 10 A which is quit efficient and powerful. However with 5040 it provides 140 grams extra thrust nearly current goes to 12 A.
