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.
