Ever wondered what makes your drone capable of aerial photography? The answer is the motor unit of your quadcopter. Yes, that is precisely what makes your drone capable enough to pull off those impressive aerial movements with ease!

So, if you’re looking to build your own quadcopter or replace your drone’s motor, this article will guide you about some of the best drone motors you’ll find on the market in 2021.

Drone Motor

Factors to Consider Before Choosing Drone Motors


Before deciding on which drone motor to buy, you must keep various factors in mind. Here are some important considerations in this regard:

#1. Drone Weight

Drone weight should be the very first factor to consider before deciding on which drone motor to buy. That’s because once you have a clear idea about the overall weight of the drone, you can know about the overall thrust of the motor required for the perfect lifting of the drone during flights. It will help maintain the speed of your drone in the air.

The approximate weight of the drone can be calculated by adding up the weight of its individual parts and components, like battery unit, motors, wires, payload, etc.

#2. Thrust to Weight Ratio

Thrust to Weight Ratio is also a very important consideration to make a decision on which drone motor to buy. The motor you select for your drone should be capable of producing about 50 percent higher thrust as compared to a multi-rotor. That’s because you need additional thrust to keep your drone safe during windy weather or at the time of flight maneuvers.

For example, let’s suppose your drone weighs 500 grams. In such a case, you’ll need to pick a motor that can generate at least twice the amount of thrust, which is about 1000 grams plus. Also, remember that the higher the thrust, the faster your drone will fly.

#3. Efficiency

The formula to calculate motor efficiency is thrust/power. A higher value of the result means higher efficiency of the motor, which in turn helps the drone fly for a longer duration.

It is generally recommended that the efficiency value of the drone motor should be 7 or above. If you have a motor with low efficiency, it will result in voltage sags for the battery and lower flight time with higher energy consumption.

#4. Torque

The torque range defines the ability of the motor to shift between RPM values. If the motor has a high torque value, it means that it’s capable to run much heavier props.

In such a case, the drone will give a faster response and lesser propeller wash. However, the motor will also suck more current.

#5. Pole Count

Another thing that you need to consider is the motor pole count. There are two options for this: quadcopter motors with a higher pole count, and other motors with a lower pole count.

Note that if you want to get rid of an additional gearbox, then it is essential that you start with a higher pole count.

#6. Brushed VS Brushless Motors

You should decide in advance whether you need a brushed DC motor or a brushless DC motor. If the motor of the drone is expected to be used for very little time, it is recommended that you connect a brushed DC motor as it will provide great as well as cost-effective output.

However, in case the motors are to be used continuously, then using a brushless motor would be a good idea for long flights.
