Drone Gimbal Motors: The Key to Stable Footage

Most drones are equipped with a camera system, and to ensure the stability and quality of the footage, a gimbal is essential. The gimbal motor for drones is a small power, precision, miniature reduction device, mainly composed of a transmission gearbox (reduction) and a brushless DC motor; the transmission gearbox, also known as a reduction gearbox, has the function of reducing speed, converting the high-speed, low-torque output of the brushless DC motor into a low-output speed and torque, achieving the ideal transmission effect; the brushless DC motor consists of the motor body and the drive, and is an integrated electrical and mechanical product. A brushless motor is a motor without brushes and commutators (or slip rings), also known as a commutatorless motor. DC motors have the characteristics of fast response, large starting torque, and the ability to provide rated torque from zero speed to rated speed, but the characteristics of DC motors are also their disadvantages because to generate a constant torque performance under rated load, the armature magnetic field and the rotor magnetic field must always maintain a 90° angle, which requires carbon brushes and commutators.
