Why BLDC motors are used in drone?

Quad copter drone usually uses Brushless Direct Current (BLDC) motor as rotor due to high efficiency and small volume. The BLDC motor speed control is very important for drone position and velocity determent. The regulating characteristics of motor can be used for speed control correction.

Which type of BLDC motor is most commonly used?

BLDC motors come in single-phase, 2-phase and 3-phase configurations. Corresponding to its type, the stator has the same number of windings. Out of these, 3-phase motors are the most popular and widely used. This application note focuses on 3-phase motors.

Why are brushless motors better for drones?

Brushless motors are better for drones because they have a much longer lifespan since they don’t have brushes that can wear down. Brushless motors are also more powerful for their size, so they are used in more professional drones that require reliability and power.

What is KV in BLDC motor?

The Kv rating of a brushless motor is the ratio of the motor’s unloaded rpm to the peak voltage on the wires connected to the coils. Knowing the Kv rating of a motor will help you determine how fast that motor will rotate when a given voltage is applied to it.

What are the types of BLDC motor?

BLDC motors are available in three configurations: single-phase, two-phase, and three-phase. Out of these, the three-phase BLDC is the most common.

Why are BLDC motors widely used in industry?

Common uses of brushless DC motors in industrial engineering are linear motors, servomotors, actuators for industrial robots, extruder drive motors and feed drives for CNC machine tools. BLDC motors are preferred in robotic applications because of their reliability, power density, compact size and ease of maintenance.

What are brushless motors for drones?

For beginners there are 2 types of motors used in drones: brushed and brushless motors. They vary in the way they work. The brushless is way more powerful for their weight than brushed motors, and they last way longer. For bigger quads: no question, brushless is king.
