Motor assembly including motor capable of being tilted, and unmanned aerial vehicle having same

An unmanned aerial vehicle, comprising:

• a body;
• and
• two motor assemblies mounted on the body,
• wherein at least one of the two motor assemblies includes a rotary actuator mounted on the body, a motor mount mounted on an output shaft of the rotary actuator, and a brushless direct current (BLDC) motor mounted on the motor mount and configured such that a rotary blade is mounted thereon,
• wherein the rotary actuator is mounted on the body such that a rotation axis (A2) thereof forms a zero angle or an acute angle with a yaw axis of the body, and
• wherein the motor mount is configured to be tilted such that a rotation axis (A1) of the BLDC motor forms an acute angle with respect to the rotation axis (A2) of the rotary actuator.

A motor assembly for rotating a rotary blade of an unmanned aerial vehicle, comprising

• a rotary actuator;
• a motor mount mounted on an output shaft of the rotary actuator;
• and
• a BLDC motor mounted on the motor mount,
• wherein the motor mount is configured such that a rotation axis (A1) of the BLDC motor is configured to be tilted so as to form an acute angle with respect to a rotation axis (A2) of the rotary actuator.
