Are drone motors AC or DC?

Drone motors are generally brushless DC motors. Brushless motors are powered by direct current (DC) electricity, which is the type of electricity generated by batteries or solar cells.

Brushless motors are the most popular choice for drones due to their efficiency, reliability, and power. They are also much quieter than brushed motors, making them ideal for drones that require stealth.

Brushless motors are composed of three main components: the stator, the rotor, and the controller. The stator is the stationary part of the motor and consists of a series of electromagnets. The rotor is the rotating part of the motor and is composed of permanent magnets. The controller is an electronic circuit board that controls the flow of electricity to the stator, causing the rotor to rotate.

Brushless motors are highly efficient and can produce a lot of torque for their size. This makes them ideal for drones which require fast acceleration and high speeds. The speed of a brushless motor is controlled by the controller, which can vary the amount of electricity sent to the stator. This allows the motor to be precisely tuned for the desired performance.

Brushless motors are also much lighter and more compact than brushed motors, making them ideal for drones that need to be as lightweight as possible.

In addition to brushless DC motors, some drones also use AC motors. These motors are powered by alternating current (AC) electricity, which is the type of electricity generated by a wall outlet. AC motors are generally heavier and less efficient than brushless motors, but they can be used in applications where brushless motors are not suitable.

Overall, brushless DC motors are the most popular choice for drones due to their efficiency, reliability, and power. While AC motors can be used in some applications, brushless motors are the preferred choice for most drones.
