The invention relates to the technical field of electric vehicles, in particular to an electric vehicle motor, which comprises an iron rim and an aluminum rim, four iron sheets are inlaid on the outer peripheral surface of the rim, the rim sleeves the periphery of the rim, the periphery of the rim is welded with the inner peripheral surface of the rim through the iron sheets, a stator is coaxially arranged in the rim, and the stator is coaxially arranged in the rim. A plurality of cast steel sheets are arranged between the outer circumferential surface of the stator and the inner circumferential surface of the rim at intervals in the circumferential direction, a magnetic steel sheet is clamped between every two adjacent cast steel sheets, the cast steel sheets and the magnetic steel sheets are fixed on the rim, the outer circumferential surface of the stator, the cast steel sheets and the magnetic steel sheets are arranged at intervals, a coil is wound on the stator, and a fixed shaft is arranged at the center of the stator. End covers are arranged on the two sides of the stator respectively, the peripheral edges of the end covers are fixed to the side face of the rim, and the fixing shaft is connected with the hole wall of a through hole formed in the center of the end covers through bearings. The rim is made of an iron material, the cost is low, the rim is made of an aluminum material, magnetic leakage can be avoided, and the magnetic force in the process of generating electricity by magnetism is effectively guaranteed.
本发明涉及电动车技术领域,尤其是一种电动车电机,包括铁质轮辋、铝质轮圈,轮圈的外周面上镶嵌4个铁片,轮辋套设在轮圈的外周,轮圈的外周通过铁片和轮辋的内周面焊接,定子同轴心布置在轮圈的圈内,定子的外周面和轮圈的内周面之间布置铸钢片,铸钢片为多个且沿周向间隔布置,相邻两个铸钢片之间夹持有磁钢片,铸钢片、磁钢片固定在轮圈上,定子的外周面和铸钢片、磁钢片间隙布置,定子上缠绕线圈,定子中心处设有固定轴,定子的两侧分别设有端盖,端盖的四周边缘固定在轮圈的侧面上,固定轴和端盖中心处开设的通孔孔壁之间通过轴承连接。本申请轮辋用铁材质,成本较低,轮圈用铝材质,可以避免漏磁,有效保证磁生电过程中的磁力。
