RELUCTANCE MOTOR, AND METHOD FOR MANUFACTURING ROTOR CORE USED IN RELUCTANCE MOTOR

摘要

With regard to the shape of slot end parts in a rotor core having as many flux barriers in the circumferential direction as the number of poles, the flux barriers being formed by alternately arranging one or more slits and core layers in the radial direction, the slit end parts are shaped so that δg i and εg i satisfy a predetermined formula, these variables representing the spacing between the first slit end to the ith slit end on the same direction side when viewed in the circumferential direction, where mg represents the number of slot end parts, ni represents a natural number equal to or greater than 1, α and β represent a number in the range of ‒1/4 to 1/4, q represents a natural number equal to or greater than 1, and Ns represents the number of slots.
