以下再针对本发明实施例的马达1的详细结构作更进一步的描述。
如图1所示,本实施例的转轴141的第一磁性单元142更具有相对的第一顶面146与第一底面147,第一外表面143邻接于第一顶面146与第一底面147之间。第一磁性单元142的第一顶面146靠近壳体121的顶壁122,第一底面147靠近壳体121的底壁123。第一磁性单元142从第一底面147朝向第一顶面146的方向渐缩而形成圆锥形构造,且第一轴承16的第一凹槽161为与第一磁性单元142形状相互匹配的圆锥形凹槽。具体而言,本实施例的第一磁性单元142例如是截顶圆锥构造,也就是第一磁性单元142的截面形状为类似梯形的构造,而第一轴承16的第一凹槽161例如是与截顶圆锥构造相匹配的截顶圆锥形凹槽,也就是第一凹槽161的截面形状为类似梯形的构造,但本发明并不以此为限。
如图1所示,本实施例的转轴141的第二磁性单元144更具有相对的第二顶面148与第二底面149,第二外表面145邻接于第二顶面148与第二底面149之间。第二磁性单元144的第二顶面148靠近壳体121的顶壁122,第二底面149靠近壳体121的底壁123。第二磁性单元144从第二顶面148朝向第二底面149的方向渐缩而形成圆锥形构造,且第二轴承18的第二凹槽181为与第二磁性单元144形状相互匹配的圆锥
形凹槽。具体而言,本实施例的第二磁性单元144例如是截顶圆锥构造,也就是第二磁性单元144的截面形状为类似梯形的构造,而第二轴承18的第二凹槽181例如是与截顶圆锥构造相匹配的截顶圆锥形凹槽,但本发明并不以此为限。
如图1所示,本实施例的定子12更包括定子导磁结构120。定子导磁结构120环设于壳体121的侧壁124的内表面1240,并位于顶壁122与底壁123之间,且定子导磁结构120环绕转子14。具体而言,本实施例的定子导磁结构120包括至少一硅钢片1201、绝缘单元1202以及线圈单元1203,绝缘单元1202位于硅钢片1201与线圈单元1203之间。须特别说明的是,本发明并不加以限定硅钢片1201的数量,硅钢片1201的数量例如是一个或多个堆栈而成。
如图1所示,本实施例的转子14更包括转子导磁结构140。在本实施例中,定子导磁结构120环绕转子导磁结构140,且转轴141穿设于转子导磁结构140。具体而言,转子导磁结构140包括磁铁单元1401以及导磁单元1402。导磁单元1402配置于磁铁单元1401与转轴141之间。转轴141穿设于导磁单元1402。在本实施例中,磁铁单元1401例如是永久磁铁,但本发明并不以此为限。
如图1所示,本实施例的定子12更包括驱动电路板127。驱动电路板127配置于壳体121内并电性连接于定子导磁结构120。具体而言,定子12的硅钢片1201与转子14的磁铁单元1401之间具有气隙,驱动电路板127产生驱动讯号,以使定子导磁结构120的线圈单元1203通电,通电后的线圈单元1203可透过定子12与转子14之间的气隙产生交变磁场,藉以驱动转子14进行旋转。
本实施例所述的马达1在启动状态下,由于第一磁性单元142的这些第一磁极面S1、这些第二磁极面S2与第一轴承16的这些第三磁极面
S3与这些第四磁极面S4之间产生的吸引力及排斥力以及第二磁性单元144的这些第五磁极面S5、这些第六磁极面S6与第二轴承18的这些第七磁极面S7与这些第八磁极面S8之间产生的吸引力及排斥力,因此,当定子12的驱定电路板127产生驱动讯号驱动转子14旋转时,搭配第一磁性单元142与第一轴承16之间连续不断的吸引力与排斥力以及第二磁性单元144与第二轴承18之间连续不断的吸引力与排斥力,进一步带动转轴141转动,这样的驱动方式能够进一步提升磁马达1的能量转换效率,换言之,藉由这样的驱动方式能够使马达1有更好的省电功效。
请参照图4,其为本发明的另一实施例的马达1a的剖面示意图。如图4所示,本实施例的马达1a与图1所示的马达1类似,不同点在于,本实施例的马达1a的第一磁性单元142a例如是截面形状为三角型的圆锥形构造。而第一轴承16a的第一凹槽161a为与第一磁性单元142a的形状相互匹配的圆锥形凹槽,也就是第一凹槽161a的截面形状为与第一磁性单元142a的截面形状相互匹配的三角形。值得一提的是,在一实施例中,第二磁性单元144也可以同时为截面形状为三角型的圆锥形构造,而第二凹槽181也可以同时为截面形状为与第二磁性单元144的截面形状相互匹配的三角形,也就是第一磁性单元142a与第二磁性单元144的截面形状相同,第一凹槽161a与第二凹槽181的截面形状相同。
综上所述,本发明实施例的马达,藉由转轴的第一磁性单元与第一轴承之间所产生的吸引力及排斥力以及第二磁性单元与第二轴承之间所产生的吸引力及排斥力来带动转轴进行旋转,且第一磁性单元的外观形状为圆锥形构造以及与第一磁性单元外观形状相互匹配的第一轴承,第二磁性单元的外观形状为圆锥形构造以及与第二磁性单元外观形状
相互匹配的第二轴承,透过这样的驱动方式配合上述第一磁性单元、第二磁性单元、第一轴承以及第二轴承的结构设计,进而提升马达的能量转换效率,并同时达成省电的功效。
