How can I choose the best drone motor?

When your drone has a problem, one of the most common causes will stem from the motor. Drone motors are extremely powerful, but the immense duress they are put under can come with consequences. When you feel like your drone is not able to maintain performance, then the motor is the first part that you should check. A damaged drone motor will have a negative on performance and overall drone safety.


What, though, matters when it comes to choosing the best drone motor?


What determines the success of purchasing new motors?


Getting the right weight of drone motor


One problem that you can often have is buying the wrong size of motor for your drone. Every drone has a recommended flying weight, and if your drone is too heavy it might struggle. You should look to get a better idea of the weight of your present motor, and the weight of the drone in full. This will give you an idea of what your drone can handle without being bogged down.


If your drone is powered by an engine that cannot handle the weight, expect performance dips and slower flight times.


Torque levels in drone motors


Torque might not be something you associate with a drone motor. It should be though. It's a very powerful part of the evaluation of a drone motor and can often lead to better performance. If you want to get a good and effective drone motor, then you should definitely look for something that produces consistent RPM values.


This means that you should be getting a drone that can respond to immediate requests mid-air. Without a high torque value, your drones might not respond in enough time to avoid disaster. If your primary concern is response time, though, getting the right torque level will really help.


What is your thrust to weight ratio for your drone?


Another important aspect is to look at the thrust to weight ratio that your drone provides. These are excellent barometers of performance. Your drone must be able to hover in the middle of the air, even on half-throttle. If your drone cannot do this, then you need a stronger motor.


The reason why the thrust to weight ratio matters is that in more controversial weather, your drone might struggle to maintain grip and lift within the air. Try and always find a drone motor that can produce double of what your drone weighs in thrust. This should give you a more powerful, reliable engine that works.


Efficiency in a drone motor


Lastly, you want to get something that is reliable and efficient. You want something with a high g/W rating, as this means that you will get a motor that can handle longer flights. We recommend that you get a g/W motor that has an efficiency rating of 7 or above. However, every drone is different.


As ever, you should look to contact us if you are unsure whatsoever about picking a drone motor. Every drone has its own purposes and needs. We can help you to find the right drone motor to get your device off the ground and into the air as soon as possible. If that sounds like a useful feature that you could use to your advantage, then we would be more than happy to assist you out.


Don't put off getting a good quality drone motor, though: it’s more than a vanity addition. The right motor can be the difference between a safe flight and risking a dangerous crash. Don’t put yourself, or others, at risk: a strong, sturdy drone motor is perfect for your long-term safety in the air.
