Many have successfully soft mounted motors, and the flight controller to reduce vibration, with some really positive results. For example, motors with the same stator size and KV, you can have very different thrust, current draw and response time even using the same prop. Differences in the design and material both have a great impact on performance.

Here I will explain a few different motor design features that contributes to better performance, which can also change the characteristics of the motor. The structure of a hollow shaft is stiffer and harder to bend than a solid rod of the same weight. But drilling the hole in the middle of the shaft can increase the cost of manufacturing significantly.

Magnets used in quadcopter brushless motors are graded according to their magnetic field strength, such as N52, N54 etc. The higher the number, the stronger the magnetic field.

A stronger magnetic field is theoretically capable of generating power more efficiently, providing more torque and a faster motor response time. When you turn a motor by hand, you can feel the notches, the stronger you can feel them is actually a bad thing because it tells you how strong the magnetic force is, and how weak it is in between magnets, which tells you the magnetic field is not even.

Weaker notches usually means a smoother motor. A lamination is the thickness of the individual sheets of metal stacked up in the motor stator, thinner lamination allows you to stack more layers of stator plates for the same height of the motor stator.

Laminations help to reduce a phenomenon known as Eddy Current, which generate heat in a changing magnetic environment. Thinner laminiations means less power is wasted on generating the eddy currents leads to undesired magnetic field and making motors more powerful and efficient.

Magnetic force degrades non-linearly with distance, so reducing the gap between the two significantly boosts the power of the motor. A smaller air gap not only makes the motor more powerful, it also improves torque and response.

The downside of tighter airgap is the increase in current draw and decrease in efficiency. Using arc magnets aka curved magnets , is a technique to bring the magnets even closer to the stator; allows for a smaller and more consistent air gap. In fact, the way a permanent magnetic field works means that with a curved magnet, the strongest magnetic point of each pole is no longer on the surface of the magnet, as it is with standard non arc magnets.

In this manner, the magnetic fields of the permanent and electromagnets are actually brought even closer together, over and above the physical reduction of the air gap. To hold the motor bell to the base, motor manufacturers use one of these methods on the bottom of the motor to lock the shaft in place: C-clip, E-clip or a screw. There are reports about C-clips popping off during flight, which resulting the motor bell flying off and causing a crash.

However, be aware that screws are also not immune to this problem. There are pros and cons to both of these designs. Closed base motors are less likely to get dirt trapped inside the bell, against the argument that, naked bottom are easier to clean the dirt out. With naked bottom, you can see clearly how far the screws are going in, and you have less chance of shorting the motor winding if the screws are too long. This happens often to beginners with closed bottom motors.

However, the closed bottom provides better strain relief to the wires in case of crashing and stretching. A flux ring is the round steel ring inside the bell that contains the magnets. The bell is usually made of aluminium, while the flux ring is made of steel because it has to respond to magnetic field lines.

The latest flux ring design is a custom shape instead of the usual round shape, which can help direct more magnetic field lines back into the motor and improve the torque. Motor manufacturers are constantly experimenting with different designs and levels of hardware integration, which has led to advances in cooling and even integrating ESC inside the motor.

Personally I think solder tabs on the motor can come in handy, it allows you to use a lighter gauge wire to save weight on less amp hungry applications. They should also be easily repairable if the wires get pulled off, which can often spell the end of a motor of typical design. While this is important for brushed motors because the brushes wear out quicker when rotating in the wrong direction, brushless motors are not limited in this way.

CW and CCW brushless motors are essentially the same motor that can spin both directions. The motors on a quad spin in different directions, the intention here is when the motors spin, all four prop nuts get tightened. To tell if you have the correct threaded motor on, simply hold the prop nut on the shaft, then start turning the motor with your hand in the direction it should spin. If the nut tightens then you have the correct one: When you receive your motors, the first thing to do is balance them.

I personally only do this on large motors though such as or bigger. I find balancing unnecessary for many brand name mini quad motors because the quality is generally good enough. There are so many motor options out there, it will give you a headache: And here is a list of top 5 motors options for mini quad voted by the community.

Hi Oscar, wonderful articles. Very detailed and informative. I am planning to build a drone for aerial photography. I want to use a mm frame with props. What would be the ideal combination of motors, ESCs and battery for my project?

My FC is DJI Naza M V2, but the motor test using Naza software assistant is not working…all I am hearing a is a click sound from the individual motors and slight twitching of them trying to rotate!

I did ESC and receiver throttle calibrations also. Anything I am missing or something I should take care of? I did not find any articles from you on this particular flight controller! Would appreciate if you can give some pointers.

Hey oscar,Ive got a mm would it be alright using a 35amp aio esc with max burst of 45amp on a kv motor with max burst of 51amp full throttle on a 3blade Would adding a uF capacitor to help to maintain the amp within the 45amp range of the esc? I will recommend bigger motors and lower KV for this size. Hey is there a chart somewhere with every motor on the market with the details about every motor? Thank you so much for writing articles in the easiest way to understand, much appreciated.

I also might include a Vtx in the future. Hi Oscar I have a Phantom 1 V 1. Would they generate more trust? Also planning on using bigger 9 in props as it has 8 in now. I am looking for more trust so that it struggles less with the gimbal and camera.

You battery needs to discharge at least 68amps. The MAH of the battery can be as high as you want it to be as long as it not to heavy. A MAH at 20C discharge is 80 amps. Use the prop size recommended by the manufacturer.

Liang Thank you so much for everything you teach us through your articles, few people are willing in teach us in this interesting way that you apply.

I have a quad whose stock engines are brushless Kv, few days ago, I ordered two engines of the same reference for have extra engines but they sent me reference Kv. Then, can I mix Kv engines with Kv engines? Does anyone have any kind of idea the propellar size, and engine size I would need for this kind of weight? Need some advice i have kv ntm motors with 3 blade props,with gimbal and gopro and mah 20c lipo and 25a 4in1 qbrain esc total weight of the cuadopter is about 1,8KGs …the copter has allot power but the motors gets very hot due to the weight and props etc, are there any other size props or other motor configuration i can use so that the i dont have this heat problem on the motors, my max flight time is about 9mins i think better stronger motors is maybe the a better solution but what motors then?

Hi Oscar, it seems like not having data for power systems is very common, which is unfortunate. I am from RCbenchmark and we developed this test stand that really helps with ensuring you have the correct setup for your creation. With this you can measure and record to your computer thrust, torque, efficiency, rpm, all in the same device. It sure beats having to time your flights to test every possible combination! Hi Oscar, i need a small help regarding selecting the right propeller size and motor KV brushless?

I think for your setup, 3S mah would be a good one. But to identify the best capacity VS flight time, check out this post. How to choose motors in that case??

Remove the blade that does not spin to see if the motor is working properly; 3.

If the motor does not work, check whether the motor gear is connected properly; 4. Remove the body shell, check if the motor cable is connected to the mainboard appropriately.

First turn on the quadcopter power switch, place it in a horizontal position, then turn on the transmitter. Push the left throttle lever to the highest position, and then pull it back to the lowest position. You will hear a clear "di, di" sound and the indicator light will stop flashing and just stay lit, meaning the frequency adjustment is completed and your quadcopter is ready to take off.

The quadcopter is not binding to the transmitter correctly, please refer to the user manual to re-modulate the frequency; 2. Battery power is insufficient, recharge the battery. Check the tightness of the blades ; 2. Adjust the trim key ; 3. Re-modulate the frequency, the quadcopter must be put on a flat ground; 4.

Blades are usually marked with A, B or R. Diagonal direction blades have the same steering, adjacent blades have opposite steering. Check and make sure that the batteries are installed by the right polarity; 2.

Single battery cell voltage imbalance is a normal phenomenon. Large current discharge will usually lead to voltage difference. This may be caused by poor contact between battery and charger, and the customer should adopt balance charge mode to charge the battery. Battery power is insufficient, recharge the battery; 2. Check whether the blades are installed correctly.
