Abstract
Provided is a rotor including a first rotor body including a first protrusion protruding from an outer circumferential surface thereof and a second rotor body stacked on and coupled to the first rotor body and including a second protrusion disposed at a position different from the first protrusion with respect to a circumferential direction and protruding from an outer circumferential surface thereof, wherein a height of the first protrusion is formed to be greater than a height of the first rotor body, and a height of the second protrusion is formed to be greater than a height of the second rotor body. The rotor is formed so that coils are wound around the respective protrusions that are divided and have relatively wide winding spaces unlike a rotor integrated with protrusions around which coils are wound, thereby increasing a coil space factor and providing an effect of facilitating a winding task.
