Abrégé
(EN)
A rotor for use in a magnet-assisted reluctance motor aims to improve output while reducing cogging torque and torque ripple in a balanced manner in a magnet-assisted reluctance motor. The rotor (3) is used in the magnet-assisted reluctance motor which rotates the rotor using reluctance torque and magnetic torque. The rotor (3) is equipped with cross-sectionally arc-shaped S-pole magnets (26s) and N-pole magnets (26n). Three of each pole of the magnets (26s, 26n) are provided so as to be embedded inside the rotor (3) in a state where the projecting sides thereof face the rotor center (Or). Each of the distances (Rs, Rn) between the centers (Os, On) of the arcs of the S- and N-pole magnets (26n, 26s) and the center (Or) of the rotor (3) are different (Rs is not equal to Rn), and the ratio of Rs to Rn is 0.92 (Rs/Rn=0.92). The outer circumferential sections (41) of the innermost layer of S-pole magnets (26s) are positioned so as to extend from the pole zones (S1, S2) to the adjacent pole zones (N1, N2).

磁铁辅助型的磁阻马达谋求输出提高且均衡性好地降低齿槽转矩和转矩脉动。转子(3)被使用于利用磁阻转矩和磁铁转矩使转子旋转的磁铁辅助型磁阻马达。转子(3)具备截面圆弧状的S极磁铁(26s)和N极磁铁(26n)。磁铁(26s、26n)各极各设有3个,以其凸侧部位朝向转子中心(Or)侧的状态被埋设在转子3内。S、N极磁铁(26n、26s)的圆弧的中心(Os、On)与转子3的中心(Or)之间的各距离(Rs、Rn)不同(Rs≠Rn),两者之比是0.92(Rs/Rn=0.92)。并且,最内层的S极磁铁(26s)的外周部(41)从极域(S1、S2)跨越到相邻的极域(N1、N2)侧地被配置。
