PROBLEM TO BE SOLVED: To disclose a rotor of a wound rotor drive motor.SOLUTION: A rotor of a wound rotor drive motor disclosed here is arranged with a predetermined air gap to an inside diameter surface of a stator, and includes a rotor core including a plurality of steel sheets stacked therein. The rotor core includes: a plurality of rotor teeth arranged so as to be apart from each other with fixed intervals on an outside circumferential surface of a rotor body along a circumferential direction with a slot interposed between the rotor teeth for winding a rotor coil thereon; and a rotor shoe formed at an end of each of the rotor teeth to face the inside diameter surface of the stator. The rotor core forms a plurality of core groups respectively having stacks of steel sheets with different shapes from one another, such that the rotor teeth have different widths from one another in respective sections along a shaft direction.SELECTED DRAWING: Figure 1 |
