具体实施方式
于以下说明中，如有指出请参阅特定附图或是如特定附图所示，其仅是用以强调于后续说明中，所述及的相关内容大部分出现于该特定附图中，但不限制该后续说明中仅可参考所述特定附图。
请一并参阅图1至图4，图1显示为本发明的马达的示意图，图2显示为本发明的马达的剖面示意图，图3显示为本发明的马达的位置感测装置的局部分解示意图，图4显示为本发明的马达的磁铁模块的分解示意图。本发明的马达A包含一马达主体A1及一位置感测装置A2。马达主体A1包含一外壳体1、一定子2及一转子3。外壳体1包含一壳主体10及一端盖11，壳主体10包含一环侧壁101及一底壁102，环侧壁101由底壁102的周缘向一侧延伸形成，且环侧壁101与底壁102共同形成一容置空间10A，容置空间10A 用以容置定子2及转子3。底壁102形成有一开口1021，开口1021是贯穿底壁102设置。底壁102的内侧设置有一轴承4A，所述轴承4A是位于容置空间10A中，而不露出于开口1021之外。端盖11可拆卸地设置于壳主体10相反于具有底壁102的一端。端盖11的内侧设置有另一个轴承4B。
位置感测装置A2是可拆卸地固定设置于底壁102的外侧，而位置感测装置A2不与位于底壁102内侧的轴承4A有连接，因此，在拆装位置感测装置A2时，无需对轴承4A进行任何拆装的动作，由此，可以有效避免轴承4A，在相关人员拆装位置感测装置A2的过程中被破坏。
具体来说，在现有常见的设置有位置感测装置的马达，因为位置感测装置设置于马达内，所以相关人员在拆装位置感测装置时，必需对马达的轴承进行拆装，为此，将容易导致轴承内部的相关构件发生偏差的问题，而此偏差的问题，将可能导致马达运转不顺畅，甚至使得马达无法正常运转。
定子2固定壳主体10的内侧。转子3包含一心轴30，心轴30的两端分别与位于外壳体1内的两个轴承4A、4B相连接外。心轴30的一端形成有一第一连接结构301及一锁孔302，第一连接结构301及锁孔302通过开口1021外露。第一连接结构301例如可以是由多个不同内径的凹槽组成，但不以此为限。锁孔302是心轴30的一端沿心轴30的一中心轴内凹形成。锁孔302例如是螺丝孔。
位置感测装置A2包含：一磁铁模块5及一检测模块6。磁铁模块5通过底壁102的开口1021，可拆卸地与心轴30相连接，而磁铁模块5能随心轴30一同旋转。检测模块6可拆卸地设置于底壁102的外侧，而检测模块6用以与磁铁模块5相互配合，据以依据心轴30的旋转状况，产生相对应的位置感测信号。
请一并参阅图4至图9，图5显示为本发明的马达的底座的剖面示意图，图6显示为本发明的马达的磁铁模块的局部分解示意图，图7显示为本发明的马达的磁铁固定座的示意图，图8显示为本发明的马达的磁铁固定座的剖面示意图，图9显示为图2的局部放大示意图。
更详细来说，磁铁模块5包含一连接组件51及一感应磁铁52。连接组件51包含一底座511、一锁固件512及一磁铁固定座513。底座511的一端包含一第二连接结构5111及一锁孔5112。第二连接结构5111的外型与心轴30的第一连接结构301的外型相对应，而底座511能通过第二连接结构5111与心轴30的第一连接结构301相互卡合。通过第一 连接结构301及第二连接结构5111的设计，可以导正底座511与心轴30的连接位置，据以增加底座511与心轴30彼此间的同心度，从而可以确保磁铁模块5可以稳定地与随心轴30旋转。底座511的锁孔5112贯穿底座511设置。
当底座511通过第二连接结构5111与心轴30的第一连接结构301相互卡合时，底座511的锁孔5112将与心轴30的锁孔5112相互连通，而锁固件512则能与底座511的锁孔5112、心轴30的锁孔302相互锁固，据以使底座511与心轴30相互固定。也就是说，底座511是通过锁固件512可拆卸地固定于心轴30的一端，而连接组件51则能据以随心轴30旋转。
底座511还包含一容槽5113。容槽5113是由底座511相反于形成有锁孔5112的一端内凹形成，且容槽5113与锁孔5112相互连通。容槽5113及锁孔5112都是位置同一轴在线。磁铁固定座513可拆卸地卡合设置于容槽5113中。当磁铁固定座513设置于容槽5113中时，锁孔5112将被磁铁固定座513遮蔽。
磁铁固定座513包含一固定槽5131及一操作孔5132，感应磁铁52可拆卸地卡合设置于固定槽5131中。操作孔5132贯穿磁铁固定座513设置，且操作孔5132与固定槽5131相连通。当感应磁铁52固定于磁铁固定座513中时，使用者例如可以是将相关工具，插入操作孔5132中，以推抵感应磁铁52，据以使感应磁铁52离开磁铁固定座513。
如图6及图8所示，在其中一个具体实施例中，磁铁固定座513的两端分别定义为一第一端513A及一第二端513B，磁铁固定座513由第一端513A内凹形成固定槽5131，磁铁固定座513的外径OD由第一端513A向第二端513B逐渐递减，固定槽5131的内径ID由第一端513A向第二端513B逐渐递增，且磁铁固定座513的外围具有多个外辅助结构5133，磁铁固定座513能通过多个外辅助结构5133卡合固定于磁铁固定座513的容槽5113中，磁铁固定座513于固定槽5131中还具有多个内辅助结构5134，多个内辅助结构5134用以使感应磁铁52卡合固定于固定槽5131中。
通过多个外辅助结构5133及多个内辅助结构5134等设计，将可以使磁铁固定座513在不使用黏胶的情况下，仍然可以稳固地与底座511相互卡合，且可使感应磁铁52在不使用黏胶的情况下，稳固地与磁铁固定座513相互卡合。
由于磁铁固定座513不是利用黏胶固定于底座511，且感应磁铁52也不是利用黏胶固定于磁铁固定座513，所以相关人员可以依据需求，置换不同尺寸、磁力的磁铁固定座513及感应磁铁52。另外，当马达A故障或毁坏时，相关人员也可以是通过简单的操作， 而取下感应磁铁52，以更换所述感应磁铁52，或者，重复利用所述感应磁铁52。
如图5及图9所示，在较佳的实施例中，底座511还可以包含一侧通孔5114。侧通孔5114是由底座511的外围内凹形成，且侧通孔5114贯穿底座511的侧壁，而侧通孔5114与容槽5113相互连通。当磁铁固定座513卡合设置于容槽5113中时，磁铁固定座513的一底部513C的一部分能通过侧通孔5114与外连通。通过侧通孔5114的设计，当磁铁模块5与心轴30相互固定时，相关人员可以是使外部工具进入侧通孔5114，以抵顶磁铁固定座513的底部513C，据以将磁铁固定座513顶出底座511。当磁铁固定座513被顶出底座511后，锁固件512将外露，而使用者即可通过操作锁固件512，以使底座511与心轴30相互分离。
需说明的于本实施例中，是以底座511包含单一个侧通孔5114为例，但底座511所包含的侧通孔5114的数量不以此为限，在不同的实施例中，底座511也可以是包含有两个彼此相面对设置的侧通孔5114。
请复参图2及图3，在实际应用中，感应磁铁52例如可以是圆柱状结构，且当磁铁模块5与心轴30相互固定时，感应磁铁52与心轴30是具有共同的中心轴线，也就是说，心轴30及感应磁铁52是位于同一轴在线。
需强调的是，于上述说明中，是以连接组件51还包含磁铁固定座513为例，但在不同的实施例中，连接组件51也可以是不包含有磁铁固定座513，而感应磁铁52可以是直接固定于底座511中。
请一并参阅图3、图10至图14，图10显示为本发明的马达的固定座的示意图，图11显示为本发明的马达的固定座与设置有磁铁模块的马达主体的分解示意图，图12显示为本发明的马达的马达主体、磁铁模块及电路组件的局部分解示意图，图13显示为本发明的马达的俯视图，图14显示为本发明的马达的局部剖面示意图。检测模块6包含一座体组件61及一电路组件62。座体组件61可拆卸地固定于外壳体1具有开口1021的一侧。电路组件62可拆卸地固定于座体组件61。
座体组件61包含一固定座611及多个锁固件612。固定座611包含多个固定孔6111。底壁102对应于多个固定孔6111具有多个锁孔1022，而多个锁固件612能穿设于多个固定孔6111，以与底壁102的多个锁孔1022相互锁固。
固定座611还包含一穿孔6112及一凹槽6113。穿孔6112贯穿固定座611设置，凹槽6113与穿孔6112相连通。穿孔6112及凹槽6113用以容置磁铁模块5。当磁铁模块5 与心轴30相互固定，且固定座611固定于外壳体1的底壁102时，磁铁模块5将穿设于穿孔6112，且磁铁模块5位于凹槽6113中。
在实际应用中，固定座611的一侧还可以是具有一避让孔6114，避让孔6114与外壳体1的底壁102的一线孔1023相互连通，而马达A内部的相关电线则能通过线孔1023及避让孔6114与外连接。
电路组件62包含一电路板621、一传感器622及多个锁固件623。电路板621可拆卸地固定设置于固定座611，传感器622设置于电路板621面对凹槽6113的一侧。当位置感测装置A2固定设置于马达A的外壳体1的一端时，传感器622将面对感应磁铁52设置，如此，当心轴30旋转时，底座511及感应磁铁52，将随心轴30旋转，而传感器622将感测感应磁铁52，以对应产生位置感测信号。
如图12至图14所示，在其中一个实际应用中，固定座611还包含一卡固槽6115，卡固槽6115的深度小于凹槽6113的深度，电路板621位于卡固槽6115中，卡固槽6115与多个固定孔6111相互连通，而电路板621固定于卡固槽6115时，各个固定孔6111的一部分被电路板621所遮蔽。
当电路板621固定于卡固槽6115时，各个固定孔6111未被电路板621遮蔽的一间隙S能使一工具(例如螺丝起子)伸入固定孔6111中，以使锁固件612不再与外壳体1的底壁102的锁孔1022相互锁固，且固定孔6111内的一活动空间6111A，能容置不再与外壳体1相互锁固的锁固件612的一部分，以使固定座611能与外壳体10分离。
也就是说，电路板621不会完全遮蔽各个固定孔6111，而使用者可以将螺丝起子伸入固定孔6111未被遮蔽的间隙S中，以操作锁固件612，而使锁固件612不再与底壁102相互锁固。当各个锁固件612都不再与底壁102相互锁固时，各个锁固件612将会被电路板621所限制，而无法离开固定孔6111，由此，可以有效地避免锁固件612遗失的问题。
如图14所示，在实际应用中，各个固定孔6111可以是包含所述活动空间6111A及一锁孔6111B，而锁固件612与底壁102相互锁固时，锁固件612的一部分可以是与锁孔6111B相互锁固，且锁固件612的一部分(例如螺丝的头部)是对应位于活动空间6111A中。在不同的实施例中，锁孔6111B也可以是贯穿孔，不局限为螺丝孔。
如图3及图15所示，需特别强调的是，本发明的马达A可以让相关人员可以有多种方式，来调整传感器622与感应磁铁52之间的间距H。举例来说，相关人员可以是通过卸除电路板621，以更换不同的电路板621、传感器622，来达到调整间距H的需求；或 者，相关人员可以是通过更换感应磁铁52，来达到调整间距H的需求；又或者，相关人员可以是通过更换磁铁固定座513，来达到调整间距H的需求。
综上所述，本发明的马达可以让相关人员可以在不拆马达主体的情况下，特别是不拆开马达主体内的轴承的情况下，进行位置感测装置的拆装。而且，本发明的马达还可以让相关人员依据需求，简单地通过更换感应磁铁、磁铁固定座、固定座、电路板其中至少一构件，来达到调整传感器与感应磁铁之间的间距的需求。
以上所述仅为本发明的较佳可行实施例，非因此局限本发明的专利范围，故凡运用本发明说明书及附图内容所做的等效技术变化，均包含于本发明的保护范围内。
