However out-runner motors are able to produce more torque which allows them to drive larger propellers used on aircraft and multorotors.Īs you shop around for some brushless motors you will notice that there is often a trend in motor naming with a series of 4 numbers and might wonder what those numbers mean. In-runner motors are often used with R/C cars as they can spin much faster than out-runner motors. The difference between the two is that out-runners have the rotor on the outer area of the motor, and in-runner motors have the rotating part on the inside while the outer shell remained stationary. There are two categories of brushless motors however with multirotors and most fixed wing aircraft you will only encounter out-runner motors are pictured above. Stator - the part that does not rotate, and has electromagnets.Rotor - the part that rotates and has the magnets mounted in a radial pattern.Brushless motor componentsĪ brushless motor consists of two main sections : These electomagnets are connected into three main sections which is why all brushless motors have 3 wires coming out of them. The motor controller (commonly known as the electronic speed controller or ESC) is the device that controls the motor by activating and deactivating specific sections of electromagnets in the motor at very specific times to cause the rotor of the motor to spin due to the magnetic force.

Simply put, a brushless motor contains a bunch of electromagnets (coils) which are connected together in specific pairs. Without going into too many technical details this guide will cover the baiscs of what you need to know in order to know all the things you need to know about when using brushless motors. In the case of multirotors, the motors generate upwards thrust which keep your drone such as a quadcopter flying. In the case of fixed wing airraft, the motors generate a forward thrust to push your plan forwards through the air. The motors of your drone is what your propellers are connected to which cause them to spin around and generate thrust to enable your drone to fly. Brushless.jpg 940×788 313 KB The brushless motor
