In recent years, the UAV market has been booming, and the UAV industry chain has brought new development opportunities. Among them, the high-speed brushless motor is one of the important components of the UAV, and its performance is directly related to the flight performance of the UAV. The rise of drones has enabled these motor manufacturers who were initially engaged in other purposes to see the development prospects and begin to use this opportunity to enter the drone market.

In recent years, with the rapid development of consumer drones, the professional drone market has also achieved rapid growth. UAVs are shifting from the consumer market to the professional market (professional grade includes high-end drones such as industrial grade and military grade). At present, the scope of application of professional-grade drones continues to expand, covering multiple fields such as electric power, forest fire protection, agricultural plant protection, police, fire protection, monitoring, inspection, surveying, mapping, and rescue.

Professional drones need at least 4 to 6 high speed brushless motors to drive the rotor of the drone, and the motor drive controller is used to control the speed and direction of the drone. The motor control system is very important for the stability of the drone. Therefore, in recent years, the market for high-speed brushless motors with high reliability, high performance and long life has developed rapidly. The motor system of professional drones should be more accurate and reliable. This is also the direction where motor manufacturers in the field of drone motors need to work hard.

In addition, in order to improve the reliability of the system under special environmental conditions such as humidity, vacuum and harmful substances, a brushless DC motor is used. Among them, the military and aerospace fields are the first to be applied to DC brushless motors.
