Top 5 Quadcopter Motors You Should Know About

quadcopter motors

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.

PROS:


  • 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.

CONS:


  • 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.

PROS:


  • These motors are very reliable.
  • Built in complete black, these motors are extremely elegant and minimal.
  • They are comparatively faster than Cobra models.

CONS:


  • 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.

PROS:


  • These are relatively cheap.
  • They are usually ready to fly.

CONS:


  • 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 2206 2000 KV:

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.

PROS:


  • 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.

CONS:


  • One can find motors with greater thrust and efficiency in the market.

EMAX RS 2205:

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.

PROS:


  • Very high thrust number.
  • This motor is overall reliable and has a high quality.

CONS:


  • Not that we know of

Still confused about which motor to choose? Here are some pointers.

How to Clean Quadcopter Motors – RC Cleaning

Motor covered in mud

Introduction:

Here are some ways to clean your motors to keeps them at their peak performance. Dirt and mud may get into the motors after a nasty crash and causes performance to drop especially if sand gets into the magnets. Let’s get started with some quick RC cleaning tips!

clean_motors_quadcopter

It's is very important to have your motors clean before every flight. I tend to clean them immediately after I get back from the field, so the next day I can immediately be back in the air.

*It may be obvious but please make sure the battery is unplugged during the cleaning process!

Things you will need:


  1. Toothbrush
  2. Compressed air
  3. Isopropyl alcohol or distilled water
  4. C-clip remover or thin flat head
  5. Toothpick or some sort of picking tool
  6. OPTIONAL: Brushless motor oil

Basic RC Cleaning:

This is for motors with dirt that is mostly on the outside of the motor bell.

  1. What I usually like to do first is clean the dirt underneath the base of the motors which gets trapped in the ventilation holes. I use something sharp like a toothpick to pick the dirt out.
  2. I then use a toothbrush to scrub the excessive dirt out. Make sure the motor is pointed downwards so the dirt does not get back into the motor bell.
  3. Some loose dirt around the base can be removed with a blast of compressed air.

Super Dirty RC Cleaning:

This is for motors with mud around motor the bell and in the copper windings

  1. Complete the basic cleaning above
  2. To get the dirt that's trapped in the motor pretty deep, you will need to take the motor apart by removing the c clip holding the motor together. Simply use a c-clip remover or use a thin flat head screwdriver to flick the clip off. Make sure not to lose it. I recommend doing this process in a clear plastic bag.
  3. Pull the base and bell apart. You should see mud stuck onto the copper windings and gravel attached to the magnets.
  4. To clean the mud off the windings, I like to dip the whole stator in isopropyl alcohol and scrub with a toothbrush. If isopropyl alcohol is not available, distilled water will also work. You can place the bell in the solvent as well. This process will not damage the motor.
  5. To remove the gravel that are magnetically attached to the magnets, you can use a blast of 120psi of air. If you don't have a compressor you can only try to flick the gravel off with a toothbrush.
  6. We then need to dry the excess solvent off, with compressed air or just letting it dry over time.
  7. Install everything back including the c-clip

(OPTIONAL STEP):

I would recommend purchasing a bottle of brushless bearing oil motor from Banggood. The product is called, "Tarot High-Speed Bearing Oil Lubricants TL2781". Apply a drop of the solution with the needle syringe that is included, directly to the bearings and spin the bell a few times.

Do not use WD-40 as the bearing oil!
