Abstract: An example includes a housing, a stator assembly, a rotor, and a self-cooling structure. The stator assembly is mounted on the housing and fitted around the rotor, the rotor is rotatably housed within the housing, the self-cooling structure is attached to the rotor, and the self-cooling structure is located at the stator assembly. The self-cooling structure comprises an outer cylinder, an inner cylinder, and a plurality of blades, wherein the plurality of blades are radially connected between the inner cylinder and the outer cylinder. A ventilation slot is formed between the outer cylinder and the inner cylinder, with multiple end-face air intake holes formed at the ventilation slot, and side exhaust holes are formed between adjacent two blades, with the end-face air intake holes being in communication with the side exhaust holes. In this way, it is capable of actively dissipating heat within the motor without altering its form.

Abstract: The present disclosure pertains to the technical field of electric motors, and discloses an electric motor and an electric toy. The electric motor includes a stator assembly, a rotor assembly, a front end cover assembly, a rear end cover assembly, a three-phase power line, and a data transmission line. The rotor assembly is sleeved on the stator assembly. The rotor assembly includes a magnetic ring, a magnetic knitting frame, an iron core, several tile-shaped magnets, a rotating shaft, and a rotor end plate. A positioning slot is arranged between adjacent tile-shaped magnets. The magnetic knitting frame is provided with a positioning boss that is inserted into the structure of the positioning slot. The electric motor allows the accurate positioning and assembling of the rotor assembly, so that the magnetic poles of the magnetic ring correspond to the magnetic poles of the tile-shaped magnet.

Abstract: The present invention provides a photographic assembly, including a pitch motor, a roll motor and a camera. A second rotor portion of the pitch motor is coupled to the third stator portion of the roll motor and a third rotor portion of the roll motor is coupled to the camera, so that a connection manner of the photographic assembly is a pitch-roll manner. When the roll motor is working, a displacement variation of the camera along a pitch axis is small. That is, a rotation interference phenomenon is weakened, so that a rotation space that needs to be reserved between the camera and the roll motor is correspondingly reduced. That is, distances between the centre of gravity of the camera and the motors are also decreased. Therefore, the photographic assembly becomes more compact at some portions, thereby achieving an objective that the volume, the weight, and the moment of inertia of the photographic assembly are reduced.

Abstract: The present application relates to the field of motors, and provides a motor, a gimbal and a mechanical are having the same. The motor includes a support, a circuit board installed on the support and including a coil circuit, a rotating shaft, and a permanent magnet. The support is installed on the rotating shaft. The permanent magnet is disposed adjacent to the coil circuit, and there is a gap between the permanent magnet and the coil circuit. The permanent magnet is of an axially magnetized structure. In the present application, the circuit board is adopted as a carrier of the coil circuit to replace an icon core in the traditional technology, thereby eliminating defects such as cogging torque, hysteresis, and eddy-current losses that are generated by an existing motor from the root. More over, the axial size of the motor and the weight and volume of the motor are reduced.
