Abstract
A motor includes a bottom and a top opposite to the bottom. The bottom is a mounting side of the motor and the bottom is inclined relative to a rotation axis of the motor.
Claims19
A motor for driving a propeller of an unmanned aerial vehicle (UAV), comprising:
- a bottom that is a mounting side of the motor mounting the motor to an arm of the UAV, a rotation axis of the propeller is coaxial with a rotation axis of the motor, and an included angle between the rotation axis of the propeller and the arm of the UAV is a fixed angle;
- and
- a top opposite to the bottom and perpendicular to the rotation axis of the motor and perpendicular to the rotation axis of the propeller, wherein a propeller disk formed by rotation of the propeller is inclined at a first inclination angle with respect to a pitch axis of the UAV, and is inclined at a second inclination angle with respect to a roll axis of the UAV;
- wherein:
- the propeller is one of four propellers of the UAV;
- the motor is one of four motors of the UAV that drive the four propellers, respectively;
- the four motors include a first motor, a second motor, a third motor, and a fourth motor;
- and
- the four propellers include a first propeller coupled with the first motor, a second propeller coupled with the second motor, a third propeller coupled with the third motor, and a fourth propeller coupled with the fourth motor;
- the first motor and the second motor are arranged at a first side of a fuselage of the UAV, the third motor and the fourth motor are arranged at a second side of the fuselage opposite to the first side, the first motor and the second motor at the first side are inclined toward each other, and the third motor and the fourth motor at the second side are inclined toward each other;
- and
- the first motor and the third motor are arranged close to a front of the fuselage, the second motor and the fourth motor are arranged close to a rear of the fuselage, the first motor and the third motor close to the front are inclined away from each other, and the second motor and the fourth motor close to the rear are inclined away from each other.
