其中，通过在转子组件上设置磁性件代替了相关技术中由硅钢片叠压而成的转子铁芯结构，不仅有利于减小电机的重量，而且免除了相关技术中轴向叠压而成的转子铁芯上，磁场要经过定子的齿部和轭部以及转子，才能形成磁场回路，从而闭合的磁力线必然呈曲线状，会出现较大的漏磁和损耗的情况。

具体地，定子齿212的端面所对应的定子组件200的面构成定子组件200的配合面。
可以理解的是，在定子组件200包括多个定子的情况下，每个定子可以包括一个定子绕组214，多个定子组合后具有多个定子绕组214，多个定子绕组214共同通电产生磁场，从而使得转子组件100在磁场的作用下转动。
进一步地，在每个定子铁芯210上具有多个定子齿212的情况下，多个定子齿212间隔分布于定子铁芯210上，使得相邻的两个定子齿212之间具有间距，从而形成定子绕组214的容纳空间，避免相邻的两个定子齿212上的定子绕组214相接触。
在上述任一实施例中，可选择地，磁性判断装置，磁性判断装置沿转子组件100的周向设置，用于获取转子组件100相对于定子组件200的转动方向。
在该实施例中，在转子组件100的周向位置安装有磁性判断装置(图中未示出)，通过磁性判断装置对转子组件100的旋转方向进行判断。
具体地，在电机通电运行时，通过磁性判断装置对转子组件100的旋转方向进行判断，从而控制定子组件200的通电状态以及定子组件200的磁场极性，实现利用非全包围式的定子组件200产生磁场，使在该磁场中的转子组件100可以受到磁力影响转动。
实施例二

在该实施例中，转子组件100包括：转盘120、插设在转盘120中心的转轴140以及磁性件160，其中磁性件160可以受到定子组件200通电后产生的磁场影响，在磁场力的作用下进行运动，带动转盘120进行旋转，其中转盘120会带动转轴140进行旋转，实现了将电能转化为动能的效果。磁性件160沿转盘的周向分布在转盘120上，可以使转盘120受力更加均匀，使电机通过转轴140稳定输出。将转子组件100中的磁性件160的材质选为磁铁，磁铁为永磁体，实现了转子组件100可以在定子组件200产生的磁场中可以持续受磁力影响旋转，磁铁具有材料易得，生产成本低的优点。
其中，转盘设置为一端面封闭另一端面开口的结构，开口端用于设置定子组件，便于对定子组件与转子组件在轴向上的拆分。
其中，通过在转子组件100上设置磁性件160代替了相关技术中由硅钢片叠压而成的转子铁芯结构，不仅有利于减小电机的重量，而且免除了相关技术中轴向叠压而成的转子铁芯上，磁场要经过定子的齿部和轭部以及转子，才能形成磁场回路，从而闭合的磁力线必然呈曲线状，会出现较大的漏磁和损耗的情况。
进一步地，其中磁性件160可以与转盘120以可拆卸的方式连接在一起，方便在后续的维修护理中，可以对磁性件160进行拆卸，避免转子组 件100中的一个磁性件160失效，导致需要对转子组件100整体进行更换，从而节省了后续的检修成本。

实施例三
如图1至图8所示，在上述任一实施例中，可选择地，定子组件200具有与转子组件100相配合的配合面，配合面与转子组件100的部分内周面相对设置。
在该实施例中，定子组件200上与转子组件100相配合的表面为配合面，配合面与转子组件100的部分内周面相对设置，也即定子组件200为非封闭结构，设置非封闭环形的且体积较小的定子组件200，对实现电机整体的轻量化和小型化，可以理解的是，该技术方案中的电机采用的定子组件200与相关技术中的封闭式环形的定子组件200不同，具有体积小质量轻的特点，并且可以保证定子组件200通电后产生的磁场可以带动处于定子组件200外侧的转子组件100转动。
可以理解的是，定子组件200的配合面可以为圆弧面也可以为平面，将定子组件200设置为非封闭式的结构即可实现转子组件100在轴向方向上与定子组件200的分离，并且，将定子组件200设置为非封闭式的结构还可以实现定子组件200的轻量化；进一步地，将定子组件200设置为弧形结构，且定子组件200的弧度与转子组件100的弧度相同，可以使定子组件200各个位置与转子组件100最短距离均相等，实现在电机运行时， 定子组件200与转子组件100更好的配合。
可选择地，在每个定子铁芯210上具有多个定子齿212的情况下，多个定子齿212间隔分布于定子铁芯210上，使得相邻的两个定子齿212之间具有间距，从而形成定子绕组214的容纳空间，避免相邻的两个定子齿212上的定子绕组214相接触。
在上述任一实施例中，可选择地，定子齿212靠近转子组件100的端面与转子组件100的旋转中心的距离均相等。
在该实施例中，每个定子齿212与转子组件100的旋转中心的距离均相等，由于定子绕组214设置在定子齿212上，使得多个定子绕组214产生的磁场对转子组件100产生的磁力均衡，提升转子组件100在转动过程中的平稳性。
在上述任一实施例中，可选择地，定子齿212的数量为两个，两个定子齿212上的定子绕组214依次通电且极性相同；或定子齿212的数量为两个，两个定子齿212上的定子绕组214同时通电且极性不同，并且，两个定子齿212上的定子绕组214的磁极交替。
在该实施例中，当设置定子组件200中设置两个定子齿212时，存在两种驱动转子组件100的方案，其中一种为两个定子齿212上的定子绕组214依次的进行通电，且两个定子绕组214在通电时产生的极性相同，两个定子绕组214依次通电，使得两个定子绕组214依次产生对转子组件100的作用力，从而驱动转子组件100连续转动；另一种为两个定子齿212上的定子绕组214同时通电，且两个定子绕组214在通电时产生的极性不同，定子绕组214产生的磁力作用于转子组件100上使其转动，并且，在通电控制转子组件100转动的过程中，两个定子绕组214的极性交替发生变化，使得两个定子绕组214依次产生不同极性的磁力，也即，两个定子绕组214依次对转子组件100上的不同磁极产生作用力，从而驱动转子组件100连续转动。
具体地，根据实际情况和工作需求来选择两种的定子绕组214的设置方案，进一步加强了电机的定子组件200设置的灵活性，提高了电机的适用性。
其中，第一种驱动方案以定子绕组214的通电极性为N极为例：具体地，当两个定子齿212上的定子绕组214依次的进行通电，且均为N极的情况下，第一个定子绕组214先通电产生N极的磁场，根据磁极异性相吸的原理，此时会对转子组件100中的磁性件160的S极产生吸引，将转子组件100中的磁性件160的S极吸引到第一个定子绕组214的位置，磁性件160的N极会经过第二个定子绕组214，第二个定子绕组214距离转子组件100中磁性件160的N极较近，此时对第一个定子绕组214断电，同时对第二个定子绕组214通电，第二个定子绕组214产生N极磁场，根据磁极同性相斥的原理，第二个定子绕组214产生的N极磁场会推动磁性件160的N极继续朝向第一个定子绕组214的方向运动，此时对第二个定子绕组214断电，对第一个定子绕组214通电，使第一个定子绕组214产生N极磁场推动靠近的磁性件160的N极继续运动，再对第二个定子绕组214通电，依此循环，使转子组件100不断旋转。
其中，第二种驱动方案为两个定子齿212上的定子绕组214同时通电且极性不同，并且，两个定子齿212上的定子绕组214的磁极交替。以下为具体说明：具体地，第一次通电时，第一个定子绕组214产生N极磁场，第二个定子绕组214产生S极磁场，同时对两个定子绕组214通电，第一个定子绕组214发出N极磁场，根据磁极异性相吸的原理，第一个定子绕组214吸引转子组件100的磁性件160的S极，第二个定子绕组214吸引转子组件100的磁性件160的N极，对转子组件100形成一个切向的作用力，此时对第一个定子绕组214和第二个定子绕组214的磁极进行切换，此时第一个定子绕组214产生S极磁场，第二个定子绕组214产生N极磁场，根据磁极同性相斥的原理，第一个定子绕组214和第二个定子绕组214会分别对磁性件160的S极和磁性件160的N极产生排斥力，使转子组件100继续转动，此时再对第一个定子绕组214和第二个定子绕组214的磁极进行切换，依此循环，使转子组件100不断旋转。
实施例四
如图1至图8所示，在上述任一实施例中，可选择地，定子齿212的数量大于等于3个，任意两个相邻的定子齿212上的定子绕组214的极性 不同。
在该实施例中，当定子齿212的数量大于等于3个时，进一步地，对其中相邻的两个定子绕组214一同通电，且使相邻的两个绕组的极性相反，使转子组件100受到一个切向方向的力，实现对转子组件100转动提供动力。
具体地，将定子齿212数量设置为三个时，开始对第一个定子绕组214和第二个定子绕组214通电，第一个定子绕组214产生N极磁场对转子组件100中磁性件160的S极吸引，第二个定子绕组214产生S极磁场对转子组件100中磁性件160的N极吸引，对转子组件100形成一个切向的作用力，然后，对第二个定子绕组214和第三个定子绕组214通电，第二个定子绕组214产生N极磁场对转子组件100中的磁性件160的N极排斥，第三个定子绕组214产生S极磁场对转子组件100中的磁性件160的S极排斥，使转子组件100继续转动，依此循环，使转子组件100不断旋转。
在上述任一实施例中，可选择地，定子绕组214的数量为3N个，磁性件160的磁极的数量为4M个；其中，N为正整数，M为正整数。
在该实施例中，对定子绕组214的数量进行了限定，即定子绕组214的数量最少为3个，在需要更多的定子绕组214数量时，需将定子绕组214设置3的整数倍个，磁性件160的磁极的数量最少为4个，在需要更多的磁性件160的磁极时，需将磁性件160的磁极设置为4的整数倍个，通过对定子绕组214的数量的限定以及对磁性件160的磁极的数量的限定可以使电机的输出效率更高。
具体地，在对电机运行平稳度需求较高时，可以将定子绕组214的数量设置为6个或者9个以及更多从而使电机中的磁极数增多，使电机的运行更加平稳。并且每个定子绕组214均是设置在定子齿212上，因此定子齿212的数量应与定子绕组214的数量设置相同。
实施例五
如图2至图4所示，在本申请的一个实施例中，可选择地，定子组件200还包括：绝缘件300，设置在定子铁芯210上，绝缘件300用于隔离定子铁芯210和定子绕组214。绝缘件300为两个，分别从上下方向隔离定 子铁芯210和定子绕组214。
在本申请的一个实施例中，可选择地，绝缘件300包括：第一绝缘部320，与定子铁芯210的上表面或下表面相贴合；第二绝缘部340，与第一绝缘部320相连接，第二绝缘部340套设在定子齿212的侧壁上；第三绝缘部360，与第一绝缘部320相连接，第三绝缘部360由第一绝缘部320的表面朝向背离定子铁芯210的方向延伸，以隔离定子铁芯210和定子绕组214。
在该实施例中，通过在定子铁芯210和定子绕组214之间设置绝缘件300，绝缘件300具有绝缘的作用，绝缘件300可隔离定子铁芯210和定子绕组214，绝缘件300能够避免定子绕组214与定子铁芯210产生电连接，提高定子绕组214工作时的稳定性。
具体地，绝缘件300包括第一绝缘部320、第二绝缘部340及第三绝缘部360。第一绝缘部320、第二绝缘部340及第三绝缘部360相配合以实现在多个方向、多个角度及多个维度上隔离定子铁芯210和定子绕组214，进而可提高定子组件200的使用安全性及稳定性。
如图7和图8所示，本申请的第二方面的实施例提供了一种电机组件，具有第一方面任一技术方案中提供的电机，和转子支架400，其上设有安装孔410，安装孔410延伸至转子支架400的一端面，安装孔410用于支撑转子组件100的转轴140并便于转轴140从安装孔410中移出。因此，本申请的实施例提供的食物处理机具有第一方面任一实施例提供的电机组件的全部有益效果，在此不再一一列举。
该实施例提供的一种电机组件，包括第一方面任一技术方案中的电机，还包括设有安装孔410的转子支架400，可以将电机中的转子组件100设置在转子支架400的安装孔410内，实现了沿着转子组件100的轴向方向上快速取出转子组件100，从而便于转子组件100的拆卸安装，进一步便于对后续对电机的日常维护和修理。
可以理解的是，还可以在安装孔410的位置设置轴承，轴承与转轴140套设在一起，使转轴140可以相对转子支架400顺畅地转动，在转子组件100通电工作时，轴承与安装孔410之间不会产生相对位移，再需要对转 子组件100进行拆卸时，可以将转子组件100连同轴承一同从转子支架400上快速取下。
本申请的第三方面的实施例提供了一种食物处理机，具有第一方面任一技术方案提供的电机，因此，本申请的实施例提供的食物处理机具有第一方面任一实施例提供的电机的全部有益效果，在此不一一列举。
在一个具体实施例中，如图9所示，食物处理机5还包括：杯体52和底座54，定子组件200设置在底座54上，转子组件100设置在杯体52上。定子组件200具有与转子组件100相配合的配合面，且配合面与转子组件100的部分内周面相对设置。
由于转子组件100能够在其轴向方向与定子组件200相分离，使得转子组件100能够随杯体52一起与底座54相分离，可使底座54中无需安装整体电机，降低底座54的高度，从而降低食物处理机5的整体高度。另外，相比于相关技术中的环状定子，本申请将定子设置为非封闭的结构，使得定子组件200的重量变轻，从而有利于实现整体产品的轻量化，方便用户提取使用，且占用空间变小，便于收纳。
进一步地，食物处理机5为搅拌机、破壁机、豆浆机、料理机、厨师机及烹饪机中的任一种。
本申请的第四方面的实施例提供了一种送风装置，具有第一方面任一技术方案提供的电机，因此，本申请的实施例提供的送风装置具有第一方面任一实施例提供的电机的全部有益效果，在此不一一列举。
本申请的第五方面的实施例提供了一种家用电器，具有第一方面任一技术方案提供的电机，因此，本申请的实施例提供的家用电器具有第一方面任一实施例提供的电机的全部有益效果，在此不一一列举。
本申请的第六方面的实施例提供了一种电动车辆，具有第一方面任一技术方案提供的电机，因此，本申请的实施例提供的电动车辆具有第一方面任一实施例提供的电机的全部有益效果，在此不一一列举。
在以上第三方面至第六方面的实施例中，均可以将需要电机提供动力的被驱动组件与第一方面实施例中的转子组件100设置在一起，再简化了产品结构的同时，实现了方便的对被驱动组件的拆卸安装。
本申请的第七方面的实施例提供一种发电装置，具有第一方面任一技术方案提供的电机，因此，本申请的实施例提供的发电装置具有第一方面任一实施例提供的电机的全部有益效果，在此不一一列举。
在本申请中，术语“多个”则指两个或两个以上，除非另有明确的限定。术语“安装”、“相连”、“连接”、“固定”等术语均应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或一体地连接；“相连”可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。在本说明书的描述中，术语“一个实施例”、“一些实施例”、“具体实施例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或实例。而且，描述的具体特征、结构、材料或特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
