What is a drone motor?

Motors for Drones and Robotics. The most common use of motors for drones and UAVs is to spin the propellers of multirotor drones to enable them to fly. Drone motors may also be found in other unmanned vehicle subsystems, such as camera and payload gimbals, flight surfaces, antenna rotators and landing gear.

How do quadcopter motors work?

The spinning of the quadcopter propeller blades push air down. All forces come in pairs (Newtons Third Law), which means for every action force there is an equal (in size) and opposite (in direction) reaction force. Therefore, as the rotor pushes down on the air, the air pushes up on the rotor.

What is KV for motors?

Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. Generally speaking the more Kv a motor has, the more RPM and more power. For example, a 9000Kv motor would be faster than a 2200Kv motor. If Kv is like horsepower, then Turns is the physical attribute of a motor.

What kind of motor does a multirotor have?

Y4 – 4 motors. It looks like a tricopter but without the tail servo. There are two normal propellers and motors in front on separate arms and two coaxial motors in the rear mounted to one arm. Mechanically it’s simpler than tricopters because of the absence of the and yaw mechanism.

What are the different types of multirotors used in racing?

More recently Drone Racing is a hot topics, where multicopters are used in racing and free-style competition. There are many types of multirotor. They are generally categorized by the number of motors used, for example a three-motored multicopter is a called a tricopter, and the configuration can also be referred to as Y3.

Which is the cheapest type of multirotor to build?

Here is an example of the bicopter avatar gunship. Bicopter could be the cheapest multicopter config to build among all because it only uses two motors and two servos. But it’s also the most difficult platform to stabilize in flight. It has the least lifting power given the fact that it only has 2 motors.

How does a multi rotor drone propeller work?

In the same way, the multi-rotor drone (UAV) is also rotated by the motor, which causes the propeller to generate lift and fly.
