| 摘要 |
The present invention relates to an electric motor including a stator and a rotor, wherein the rotor comprises: a shaft; a plurality of segment cores having a plurality of yoke parts in the circumferential direction and a pole protruding radially in the radius direction of each yoke parts, and coupled to a circumference of the shaft; a rotor coil winding on the segment cores; and a segment core supporting unit mounted on each double end sides of the segment cores in the circumferential direction to support the segment cores. Therefore, the present invention may improve a coil space factor by suppressing the torsion of the rotor coil when the rotor coil is winding. |
