An actuator includes a controller, a motor and a sensor device. The controller includes a housing, and the motor includes a rotor, and the rotor includes a rotating shaft. The motor is mounted on the outside of the housing, and the sensor device includes a magnet and a sensor, the magnet is mounted on the rotating shaft of the motor, and the sensor is mounted inside the housing. The actuator has a good waterproof performance and anti-interference ability. This disclosure also relates to an electronic clutch system having the actuator.

Actuator and electronic clutch system

A brushless direct current electric motor includes a first sub-motor and a second sub-motor. The first sub-motor and the second sub-motor share a common rotor, and each comprises an independent stator. The stators of each sub-motor comprises a plurality of teeth and a plurality of windings. The teeth of the first sub-motor and the teeth of the second sub-motor are interleavingly arranged in a circumferential direction or arranged side by side in an axial direction. The first sub-motor and the second sub-motor are configured to cooperatively work as a single electric motor to output a normal power. When one of the sub-motors breaks down, the other sub-motor can be operated independently to enhance reliability and safety of the brushless direct current electric motor.

A video recording method and apparatus are disclosed. The method includes acquiring video data; buffering the video data at a native layer for which memory allocation is not limited; and performing encoding to obtain a video file according to the video data buffered at the native layer. Embodiments of the present disclosure solve the problem that a garbage collection (GC) mechanism is frequently triggered and the phenomenon of out of memory (OOM) occurs when image data is buffered at a Java layer, and achieve the effect that there is no need to trigger the GC mechanism and the phenomenon of OOM does not occur.

Video shooting method and apparatus

A BLDC motor, has a first sub-motor and a second sub-motor. The first and second sub-motors have independent input terminals and a common rotor, including a common output shaft. In a normal operating mode the two sub-motors operate together as one motor to output a normal operating power of the motor. In an emergency operating mode, when one sub-motor has become faulty and generates a braking torque, the normal sub-motor is operated to generate a torque to compensate for the braking torque produced by the faulty sub-motor.
