Description

盘式电机同股多芯线圈平板式定子 技术领域
本发明涉及盘式电机，具体说是一种盘式电机同股多芯线圈平板式定子。
同股多芯线圈平板式定子。
 背景技术
传统的盘式电机的功率密度偏低，本发明人通过实验发现了可以突破传统盘式电机瓶颈的盘式电机技术方案。应用于盘式发电机，针对盘式发电机的定子，现有技术的盘式发电机定子带有铁芯，体积大、重量大，铜占比低，使得输出效率低，用电质量差，灵活性差，因此，盘式电机长期以来，其效率低已成为公认的瓶颈，使之在一些特殊领域之外难以得到广泛的应用。
 技术问题
本发明所要解决的技术问题是提供一种盘式电机同股多芯线圈平板式定子，充分利用转子上永久磁铁所提供的磁场，大幅提高电机的输出效率和功率密度，提高用电质量。
 技术解决方案
所述的盘式电机同股多芯线圈平板式定子，设有定子线圈和平板状的以绝缘不导磁材料制作的定子基座，其特征在于：在定子基座的两侧面固定设有单个或多个空心的线圈组，单个或多个线圈组排布为环形或排布为长条状，横向相邻的一周多个线圈组之间由线圈线依次串接组成线圈单元；
所述线圈组由一层单线圈或与定子基座垂直方向重叠的多层单线圈堆叠而成，线圈单元中同一层各单线圈的直径和圈数相同，各线圈组的层数相同；
所述单线圈由两芯或两芯以上的带绝缘层线圈线合为非绞绕的一股，同一单线圈内的线圈线在同一层平面内同旋向始终相互平行贴合绕制。
每个单线圈由同样层数的偶数层单层线圈组成，单层线圈的轴向线数为单根，单层线圈的轴向尺寸为线圈线的宽度；一个单线圈内的单层线圈依次连续串接，所述单线圈中的单层线圈仅一个旋向绕制。
各线圈组的绕入端和绕出端均位于线圈的外圈不径向跨越金属线地切向引出。
对于线圈组环形排列的定子，单线圈中的多芯线径向位置相对圆心距离依次排列，每一单线圈中的多芯线与相邻的单线圈中的多芯线在不同圆周上顺次变换连接，使每一芯线离转子的中心距离平均值一致或接近。
优选地，所述线圈线的截面为扁平形状。
优选地，排布为环形的定子线圈的外周直径与定子线圈的厚度之比为6~60，排布为直线的定子线圈的宽度与定子线圈的厚度之比为1.2~50。
优选地，单线圈设有在上层单层线圈和下层单层线圈各一个接线端，相邻串接的单线圈按照如下的排布设置连接：
相邻的单线圈之间的连接线根据安装状态下相邻的单线圈的缠绕旋向布置，相邻的单线圈的缠绕旋向如果相同，则前一单线圈的出线接线端与下一单线圈的进线接线端同为在上层单层线圈之间连接或同为在下层单层线圈之间连接；相邻的单线圈的缠绕旋向如果相反，则前一单线圈的出线接线端与下一单线圈的进线接线端在上层单层线圈与下层单层线圈之间连接。
优选地，设有多套独立的线圈单元，每一套线圈单元均设有单层或多层单线圈，线圈单元中的各芯线圈线在入线端和出线端分别电连接。
一种实施例为，定子基座上每一套线圈单元中的单线圈经过同一个与定子基座平行的平面布置连接。
另一种实施例为，定子基座上每一套线圈单元中的单线圈在不同平面内交错布置连接。
 有益效果
本发明的电机定子通过合理的线圈排布，尽量提高磁场空间的利用率，省略了铁芯，杜绝了铁损，同时将空间利用来提高铜占比，在定子线圈的两侧一对带有永久磁铁的转子距离足够近的情况下，发现在基于合理的结构和工艺条件下，同等体积和质量的电机输出功率和效率有大幅提高，远高于目前的桶式电机和盘式电机的输出效率。
将定子线圈的线圈设置为同股多芯，然后在输入和输出端并接，尽量减小了涡流和由此带来的铜损，并且绕线方式使线圈厚度最低仅有两线宽度时，一对定子的间距接近可以达到极限值，缩短一对定子之间的磁通路径，绕线方式尽量去除了间隙，最大化提高铜占比，使得磁场空间利用率最大化。
相邻的单线圈交错反向串接，由于磁铁的排布为N极和S极交替排列，单线圈的平面个数和轴向大小一一对应转子的磁铁个数和大小，这样的单线圈连接，可以有效提高电压输出。
相邻的单线圈中的多芯线顺次变换相对位置，使得每一芯线离转子的中心距离平均值一致或接近。可以减少多芯线之间电势差，有利于多芯线的输出直接并线连接，提高输出功率。
如果制作成多层，并不影响同股多芯的结构及优势，可以将多个独立的线圈单元合并提高输出功率。减少磁场不对称性，实现等电位输出，减少内阻损耗，提高功率密度，提高输出效率，通过实验证明效率有明显提高。而多芯线可实现同一平面上的磁场分布、磁场对称性比多层叠加的方式精度更高，电动势对称性更加精准。
多芯的0.3~10平方毫米截面线圈线并绕，相对单芯的线圈线铜损降低到30%~50%。
多芯线并绕的方式相对于多芯绞绕方式，有效铜占比是后者的两倍，因此并线后带载能力更高。也因此可以减小线圈线的横截面积，进一步降低铜损。
本发明定子的两侧配套一对带有一周交变磁场的转子来作为发电设备使用，由于多个独立的线圈单元无相位差输出，使得输出频率在300Hz以上时才能实现输出的连续性，才能为变频模块提供更优质的电源。
定子铜占比可以达到50%以上，是传统电机的5倍或以上。有铁芯盘式电机的感性负载小，过载能力弱，而本发明的无铁芯片盘式电机过载能力强，超出有铁芯电机的50%以上。根据实测，输出功率在200KW以上的输出效率达到95%~98%。

 本发明的实施方式
下面结合附图和实施例对本发明进一步说明：如图1、2中所示的盘式电机同股多芯线圈平板式定子，设有定子线圈和平板状的以绝缘不导磁材料制作的定子基座1，在定子基座1的两侧面固定设有单个或多个空心的线圈组2，不带铁芯，因此减小了体积和重量，也没有铁损。当定子线圈两侧的带永久磁铁的转子之间的距离足够近，绝大部分的磁力线均会穿越定子线圈。而省略铁芯所留下的空间排布线圈，在合理布线的前提下，得到的额外输出可以超过铁芯对磁力线的收集带来的好处。
线圈组2是指垂直于定子基座方向看单体但是相互重叠的一叠线圈或总体仅单层线圈。通常，定子线圈在定子基座1的两侧面对称安装。
单个或多个线圈组2排布为环形或排布为长条状，当定子基座1为圆盘形时，为普通盘式电机，线圈组2均匀排布为环形的一周；当定子基座1为长条形时，为直线电机，线圈组2均匀排布为直线。
横向相邻的一周线圈组2之间由线圈线依次串接组成线圈单元3。可以有多组线圈单元同步产生电动势输出，为了提高输出功率，将多组线圈单元的输入端和输出端分别连接，在电势差足够低的情况下并接既可以提高输出功率又可以降低涡流损耗。
所述线圈组2由一层单线圈或与定子基座垂直方向重叠的多层单线圈堆叠而成，线圈单元3中同一层各单线圈的直径和圈数相同，各线圈组的层数相同。较佳的一种实施例中，线圈组2仅由一层单线圈构成。
每个单线圈4由同样层数的偶数层单层线圈5组成，典型的单层线圈5设置有两层，单层线圈5的轴向线数为单根，单层线圈5的轴向尺寸为线圈线6的宽度；一个单线圈4内的单层线圈5依次连续串接，所述单线圈4中的单层线圈5仅一个旋向绕制。例如，从外圈绕入，到达中心位置后线圈线转入下一层，同方向由内向外绕制，直到最外圈。实现绕入端和绕出端都在最外层，而不需要多用一层空间跨越引线，各线圈组2的绕入端7和绕出端均位于线圈的外圈不径向跨越金属线地切向引出。
所述单线圈由两芯或两芯以上的带绝缘层的线圈线6合为非绞绕的一股，在同一层平面内同旋向始终相互平行贴合绕制构成，同一单线圈中单层线圈5的线圈线在一个平面内。这样的布置可以尽量提高磁场空间的利用率，增加铜占比，定子位于尽量短距离磁通路径的最强磁场范围内，因而可以提高功率密度。单层线圈并线后也更能提高负载能力，多芯线圈可以减少涡流，也就是减小了铜损。
较佳地，所述线圈组2中的线圈仅一个旋向绕制。可以使生产效率高，降低成本。
在安装时的接线选择为，单线圈设有在上层单层线圈5和下层单层线圈5各一个接线端，相邻串接的单线圈4按照如下的排布设置连接：
相邻的单线圈之间的连接线根据安装状态下相邻的单线圈的缠绕旋向布置，相邻的单线圈的缠绕旋向如果相同，则前一单线圈的出线接线端与下一单线圈的进线接线端同为在上层单层线圈5之间连接或同为在下层单层线圈5之间连接；相邻的单线圈的缠绕旋向如果相反，则前一单线圈的出线接线端与下一单线圈的进线接线端在上层单层线圈5与下层单层线圈5之间连接。
单线圈的平面个数和轴向大小一一对应转子的磁铁个数和大小，由于磁铁的排布为N极和S极交替排列，这样的单线圈连接，可以有效的提高电压输出。
以具体的实施例说明单线圈之间的连线排布：
相邻单线圈连线布置实施例一：单线圈作为半成品，均以同一旋向绕制，当相邻的单线圈固定在定子基座上的上表面均按照同一方向绕向时，前一单线圈的出线接线端与下一单线圈的进线接线端连接，前一单线圈的出线接线端与下一单线圈的进线接线端是上层单层线圈和下层单层线圈之间连接，连接线均不在同一层单层线圈之间。
相邻单线圈连线布置实施例二：单线圈作为半成品，均以同一旋向绕制，当相邻的单线圈固定在定子基座上的上表面按照绕向方向交替排布时，前一单线圈的出线接线端与下一单线圈的进线接线端连接，前一单线圈的出线接线端与下一单线圈的进线接线端是上层单层线圈和上层单层线圈之间连接，或者下层单层线圈和下层单层线圈之间连接，连接线在同一层单层线圈之间。
相邻单线圈连线布置实施例三：单线圈作为半成品，均以同一旋向绕制，当相邻的单线圈固定在定子基座上的上表面没有规律排布时，前一单线圈的出线接线端与下一单线圈的进线接线端连接，下一相邻的单线圈的缠绕旋向如果相同，则前一单线圈的出线接线端与下一单线圈的进线接线端同为在上层单层线圈5之间连接或同为在下层单层线圈5之间连接；下一相邻的单线圈的缠绕旋向如果相反，则前一单线圈的出线接线端与下一单线圈的进线接线端在上层单层线圈5与下层单层线圈5之间连接。
如图2所示，对于线圈组环形排列的定子来说，单线圈中的多芯线每一芯线相对圆心的距离依次排列，每一单线圈中的多芯线与横向相邻的单线圈中的多芯线在不同的圆周上顺次交错连接，使每一芯线离转子的中心距离平均值一致或接近。可以减少多芯线之间电势差，降低线材负载损耗。
为了提高铜占比，所述线圈线的截面为扁平形状。理想截面形状为矩形，可以提高空间利用率。
作为一种实施例，排布为环形的定子线圈的外周直径与定子线圈的厚度之比为6~60。这一比值范围内的功率密度高。也就是使得定子线圈两侧的转子磁场之间的距离足够近，磁力线集中在定子线圈所处的空间中，才能提高磁通密度，有高的功率输出。
同样道理，作为另一种实施例，作为直线电机，排布为直线的定子线圈的宽度与定子线圈的厚度之比为1.2~50。直线电机这一比值范围内的功率密度高。
作为实施例，设有多套独立的线圈单元3，每一套线圈单元3均设有单层或多层单线圈。可以有多支独立的输出，进而可以串接为高压输出或进线端相互连接，出线端相互连接，提高输出电流，又避免了涡流损耗。或者其他接法用途可以匹配出需要的功率和电压输出。
一种多层单线圈的排布实施例为，定子基座1上每一套线圈单元中的单线圈经过同一个与定子基座1平行的平面布置连接。
另一种多层单线圈的排布实施例为，如图3所示，定子基座1上每一套线圈单元中的单线圈在不同平面内交错布置连接。可以减少磁场分布不对称性，实现等电位输出，减少内阻压降损耗。
