Document Type and Number:

WIPO Patent Application WO/2019/151660

Kind Code:

A1

Abstract:

An embodiment relates to a rotor and a motor comprising same, the rotor comprising: a rotor core; and a plurality of first magnets and second magnets arranged along the outer circumferential surface of the rotor core, wherein each of the second magnets is disposed between the first magnets, and the outer circumferential surface of each of the first magnets has a curvature greater than that of the outer circumferential surface of the second magnet. Therefore, the motor can reduce cogging torque by using the first magnet and the second magnet having different shapes, and thus can improve the quality of the motor.
