A brushless motor controller is an electronic device used to control and drive the operation of a brushless motor. It controls the speed, direction, start stop and other operations of the motor through electrical signals, and is widely used in fields such as automobiles, drones, and industrial automation.

Brushless motor is an efficient, low noise, and low maintenance cost motor that has been widely used in various fields in recent years.

Planetary reducer is a high-precision deceleration device commonly used in mechanical transmission, which decelerates the rotation of the input shaft and transmits it to the output shaft, thereby reducing the speed of the output shaft. This deceleration method mainly utilizes the transmission coordination between the planetary gear, the sun gear, and the planetary gear shaft, which has a strong deceleration ratio and transmission ability.
