So how do quadcopter motors work?
First off, the propellers of your drone are connected to a motor. These quadcopter motors cause the propellers to spin around and create the thrust which is needed to make the quadcopter fly. In the case of multiple motors, the thrust is generally upward which keeps the drone flying. In the case of fixed wing aircraft, the thrust generated is forward which pushes the machine ahead.
When dealing with quadcopters, you will have to deal with two kinds of quadcopter motors namely, brushed motors and outrunner brushless motors. Usually, brushed motors are found in toy grade drones. They are cheap to manufacture but have a very short lifespan. Brushless motors are stronger and more durable. Brushless motors mainly comprise of rotor and stator. The stator contains the electromagnets whereas the rotor is the part that rotates and has magnets mounted on it in a radial pattern.
They contain a bunch of electromagnets which are connected together in specific pairs. The electronic speed controller or motor controller controls the motor by activating and deactivating certain sections of the electromagnets at certain times which causes the motors to spin due to the magnetic force. These electromagnets are connected to three main sections.
The top 5 quadcopter motors are-
This particular battery model is a complete redesign of 22XX sized quadcopter motor. Lumenier RX 2206 motor has been engineered from the very beginning and is a perfect blend of high-end performance and elegance. These motors certainly have a lot to give.
- It is ultra light weight.
- The flanged aluminum lock nut is attached to each motor which ensures that the propellers do not come loose during the flight.
- It delivers a decent performance.
- It is a cost-effective motor.
- It is not very powerful.
ROTORGEEKS 2204 2300 KV:
These motors have been recently launched in the market. These motors give a befitting competition to the legendary Cobra’s 2204 (5) 2300. These Cobra motors have been a huge success in the high-end FPV market since a year. As Cobra has been suffering from relatively poor quality controls, these Rotorgeek’s motors have managed to gain an upper hand in the drone motor market.
- These motors are very reliable.
- Built in complete black, these motors are extremely elegant and minimal.
- They are comparatively faster than Cobra models.
- They are not the most premium model available in the market. One can find better options.
RCX 2205 2633 KV:
These are by far the cheapest motors available on this list. RCX 2205 completely matches Cobra’s thrust tests and in many cases, even exceeds their numbers. These motors usually come balanced out of the shop which means that they are completely ready to fly.
- These are relatively cheap.
- They are usually ready to fly.
- These motors may draw in excess of 30 A.
- There have been many issues with bells flying off in the smallest of all the crashes.
X Nova is a very popular name in the 3D Heli world. It usually deliver a very high-quality performance and have built solid reliability. This particular model gives a maximum thrust of 1141 grams on 6045 tri blades. It is perfect for those pilots who want to push their 6 inches setups to extreme limits.
- This model is ideal in terms of thrust tests.
- The temperature also remains low while these motors are in use.
- These motors are as promising as Cobra’s and Tiger’s motors.
- One can find motors with greater thrust and efficiency in the market.
This latest motor of Emax has a huge potential. It is an improved version of Emax 2206. The thrust numbers of Emax RS 2205 are huge. It produces over 1 kg of thrust on a 5045 bullnose propeller. So technically speaking, Emax RS2205 has a potential to outperform Cobra motors.
- Very high thrust number.
- This motor is overall reliable and has a high quality.
- Not that we know of
