Abstract: A rotor assembly includes a propeller, a motor, and a connection assembly. The motor includes a stator and a rotator rotatable with respect to the stator, and is configured to drive the propeller to rotate through the rotator. The connection assembly is arranged between the propeller and the motor, and includes a locking member and an elastic member. The elastic member is configured to provide a force onto the locking member in response to the propeller being locked to the motor by the locking member, to maintain a locking state of the locking member.

Abstract: A rotor assembly includes a propeller, a motor, and a connection assembly. The motor includes a stator and a rotator rotatable with respect to the stator. The connection assembly is configured to connect the propeller to the motor and includes a locking member that is arranged between the propeller and the motor. The locking member is configured to rotate with respect to the rotator and the propeller in a rotation direction identical to a rotation direction of the propeller in operation to lock the propeller to the motor.

Abstract: A follow focus device includes a signal receiver, a controller electrically connected to the signal receiver, and a control interface electrically connected to the controller and configured to be electrically connected to a camera device. The signal receiver is configured to receive a control instruction for controlling a focal length of a lens of the camera device and send the control instruction to the controller. The controller is configured to generate a control signal according to the control instruction and send the control signal to the camera device via the control interface.
