This application relates to the field of aerial vehicle technologies, and provides a motor, a gimbal, and an unmanned aerial vehicle. The motor includes: a first and a second connection terminals, where the first connection terminal includes a circuit board including a coil circuit; the second connection terminal includes a permanent magnet adjacent to the coil circuit, wherein there is a gap between the permanent magnet and the coil circuit, and the permanent magnet has an axial magnetization structure; one of the first and the second connection terminals is fixedly connected to a lens module and sleeved over the lens module, and the other is movably connected to the lens module and sleeved over the lens module. In the foregoing manner, the overall size and weight of the motor are greatly reduced, and therefore, the motor has the advantages of a compact structure, a small size, and a light weight.
