Choosing motors for suspension for GoPro

Action cameras allow you to capture the most exciting moments in our life and share them with friends. However, for high-quality video, mechanical image stabilization is needed. The Internet is full of ready-made solutions, but when it stopped enthusiasts, true to the principle of "do it yourself." Moreover, with the development of 3D printing, everyone can create to their own taste and, of course, color. The inevitable purchase of a controller and motors. Let's start with the last.

If you drive “Gimbal motor” into the search for an online store, then, unfortunately, we will get a huge amount of unnecessary things and several dozen offers for the motors we are interested in. Most often, there are motors from DYS, Emax, Ldpower, RCTimer, iPower and “Nameless Chinese Firm”. There are not many reviews and reviews. I chose the most successful models in terms of parameters and rating for three different categories.

Cheap and angry (nameless Chinese company):
2208-80T for $ 8.44 ( * ) and 2208-90T (hollow shaft) for $ 9.13 ( * )

The first motor can not be called substandard. Low cost is achieved at the expense of mass rather than at the expense of savings on materials. It can be found in many ready-made hangers from China, such sets ( * ) are also developed for this motor. Want a brand? Here is the same motor ( * ) twice as expensive.

The second looks similar to the model of the company DYS, although the stated top characteristics are in doubt. The hole in the center allows you to avoid unnecessary trouble with wires.

Oddly enough, these cheap engines are record breakers in the number of orders on the online sites and have an almost flawless rating.

Small and economical:
iPower GBM2208-80T for $ 15.95 ( * ) and DYS BGM2208-80 for $ 14.95 ( * )

We turn to the motors that have a brand. These two will be pleased with the small size and high resistance of the windings, which will save battery power. This is useful if you, for example, make a suspension for a bicycle helmet and do not want to carry extra weight on your head.

Small and powerful:
RCTimer BGM2804 for $ 14.68 ( * ) and DYS BGM2606-90 for $ 14.49 ( * )

These motors differ from the previous ones in a slightly higher torque. This is achieved by changing the shape (flatter) and reducing the resistance of the windings (1.5 times). Consequently, the motors operate at several high currents. Although, in the case of multicopter, the difference will not be noticeable.

General remarks
All motors weigh about 40 grams, which is the minimum figure for this class.

Components of the motor depends on the manufacturer. You are guaranteed to receive a full set of screws from RCTimer and DYS.

Usually suspensions and motors are designed for 9-12 volts (3s). Higher voltages / currents can easily melt the windings. RCTimer BGM2804 accurately withstands 15 volts (4s), for the rest of the motors it is better to programmatically limit the voltage.

For those who have not set about trying to build their own suspension, there is the easiest ready ( * ).



Conclusion
For myself, I chose the RCTimer BGM2804 for a small height (15 mm) and working with 4s batteries.
It remains to wait for the parcel and good weather for filming.

I wish you successful crafts and smooth video!

UPD: a small motor for cameras, like the Mobius .
