Abstract

一种新结构永磁发电机转子,有一转轴(1),其特征是在转轴(1)的外面有一个中间有孔的多棱柱体(2),在此多棱柱体(2)的外柱面上分别粘接条形永磁体(3)。本实用新型磁性材料用量小,成本低,磁性能高,破碎率极低。

Description

一种新结构永磁发电机转子
本实用新型涉及一种发电机转子。
现有的小功率永磁发电机转子,其磁体均为实心圆柱形,它的一个缺点就是整个转子都由铁氧体永磁材料构成,价格太高了。实际上,其中心部位的永磁材料只起填充作用,只由较外部的铁氧体永磁材料就能产生足够的发电机所需要点有效磁场。此外,由于使用时沿圆柱体外表面要形成多个(6或8个)磁极,故容易因磁极中心部位收缩率大而边缘上收缩率小而破碎,而且磁性越高,破碎率越大,以致造成严重损失。
本实用新型的目的是提供一种新结构永磁发电机转子,它能弥补现有转子的上述不足。
本实用新型有一转轴,其特征是在转轴外面有一个中间有孔的多棱柱体,在此多棱柱体的外柱面上分别粘接条形磁体。
本实用新型磁性材料用量小,成本低,磁性能高,破碎率极低。
下面通过实施例和附图说明本实用新型。
附图为本实用新型的结构示意图。
本实施例为一六极转子,有转轴(1),它的外边是一个中问有孔的正六棱柱体芯(2),其材料可采用铸铁、钢或矽钢片等,棱柱体芯(2)的外柱面上分别粘接条形永磁铁氧体(3)。经磨削加工外圆后即为本实用新型。
