Description

具可变匝数绕组线圈的永磁电机装置及其控制方法 技术领域
本发明涉及一种电机装置，特别是一种具可变匝数绕组线圈的永磁电机装置。本发明还涉及此电机装置的控制方法。
现有技术
由于全球暖化及空气污染的问题日益严重，维持地球生命的系统正产生大规模的改变；因此，如何降低温室气体排放已成为了一个重要的议题；温室气体排放的其中一个主要的来源为车辆，故在环保意识抬头的现今，电动车已经成为了一个未来的主流；然而，目前电动车常采用的永磁电机仍有着许多缺点有待改进。
例如，电动车为了使电机能具有高扭力，电机的设计上通常不会考虑省电效果，因此使电机极为耗电，进而降低了电动车的续航力。
另外，若为了使电机能具有高省电效果，电机的设计上通常则不会考虑扭力，因此上述设计虽可使电动车具有较高的续航力，但在需要高扭力的场合，如起步、爬坡及载重等，则无法提供较佳的效能。
此外，若为了使电机能同时兼顾省电效果及扭力，通常需要采用更大的电机或加入变速箱，如此则会使电动车的体积及重量增大，进而影响到电动车的设计，还需增加电池容量。
电机针对其应用负载需求，在省电效果、扭力、转速及功率间有不同的设计。因此，如何提出一种永磁电机装置，能够有效改善现有技术的永磁电机的各种缺点已成为一个刻不容缓的问题。

请参阅图1，其为本发明的具可变匝数绕组线圈的永磁电机装置第一实施例的电机装置图。如图所示，具可变匝数绕组线圈的永磁电机装置1可包含磁铁11、电枢12、切换装置13、极性变换装置14及电源(为了清楚表示附图，图中仅绘示电源的电极E+及E-)。
磁铁11可产生磁场。
电枢12可包含多个电枢齿121及多个绕组122；所述多个绕组122可分别绕设于所述多个电枢齿121上，使电枢12产生的磁场可以与磁铁11产生的磁场相互作用。
极性变换装置14可与电源连接，并可通过切换装置13与所述多个绕组122连接，以控制磁极变换；在较佳的实施例中，若永磁电机装置1为有刷电机，极 性变换装置14则可为电刷；若永磁电机装置1为无刷电机，极性变换装置14则可为电子开关，如MOS、BJT等晶体管。
在本实施例中，永磁电机装置1可为内转子装置，但仅为举例说明而已；在其它较佳的实施例中，永磁电机装置1也可为外转子装置或其它各种不同的电机装置。
请参阅图2、图3及图4，其为本发明的具可变匝数绕组线圈的永磁电机装置的第一实施例的绕组的第一示意图、第二示意图及第三示意图。如图2所示，各个绕组122可包含第一线圈L1及第二线圈L2；在本实施例中，第一线圈L1及第二线圈L2的匝数为50。
切换装置13可包含多个开关；在本实施例，切换装置13可包含第一开关S1、第二开关S2及第三开关S3，第一开关S1、第二开关S2及第三开关S3分别与第一线圈L1及第二线圈L2连接；其中，切换装置13能切换第一开关S1、第二开关S2及第三开关S3以改变第一线圈L1及第二线圈L2的串并联状态。
第一线圈L1的第一端可分别过第一开关S1及第二开关S2与第二线圈L2第一端及第二端连接，而第一线圈L1的第二端可与电源(未绘于图中)的第一电极E+连接，并可通过第三开关S3与第二线圈L2的第二端连接；第二线圈L2的第一端更可与电源的第二电极E-连接。
如图3所示，当第二开关S2导通时，第一线圈L1及第二线圈L2为串联状态，此时绕组122的总阻抗相当于匝数为100的线圈，而通过绕组122的总电流为I；当第一线圈L1及第二线圈L2串联时，其相当于绕组122具有一个匝数为100的线圈；此时，永磁电机装置1处于省电效果较高但转速较低的状态。
如图4所示，当第一开关S1及第三开关S3导通时，第一线圈L1及第二线圈L2为并联状态，此时绕组122的总阻抗相当于匝数为50的线圈，而通过绕组122的总电流为2I；当第一线圈L1及第二线圈L2并联时，其相当于绕组122具有二个匝数50但并绕的线圈；此时，永磁电机装置1处于转速较高但省电效果较低的状态。
根据本发明的实施例，永磁电机装置1的各个电枢齿121上的绕组122可包含多个线圈L1及L2，且所述多个线圈L1及L2可通过多个开关互相连接以改变所述多个线圈的串并联状态以视情况在高省电效果及高转速之间调整电机性能， 使电动车不但具有高续航力，且可在需要高转速的场合也能有极佳的效能；另外，上述的结构设计使永磁电机装置1可在不增加体积及重量的情况下同时兼顾省电效果及转速，故确实可以改善现有技术的缺点。
由上述可知，本实施例的永磁电机装置1可经过切换装置与线圈连接，使这些线圈通过串联或并联的各种组合，达成电机提升省电效果，扭力，转速，功率的目的。
本实施例的永磁电机装置仅为举例，永磁电机装置可应用于各种不同类型的永磁电机，例如直流无刷电机及直流有刷电机，其结构可依实际需求改变，本发明并不以此为限。
值得一提的是，根据本发明的实施例，永磁电机装置的各个绕组可包含多个线圈，且所述多个线圈可通过切换装置互相连接以改变所述多个线圈的串并联状态以视情况在高省电效果及高转速之间调整电机性能，使电动车不但具有高续航力，且可在需要高转速的场合也能有极佳的效能。
此外，现有技术的永磁电机为了能同时兼顾省电效果及转速，通常需要采用更大的电机或加入变速箱，如此则会使电动车的体积及重量增大，进而影响到电动车的设计，还需增加电池容量。相反的，根据本发明的实施例，永磁电机装置可通过改变各个绕组的线圈的串并联状态以调整电机的转速及省电效果，因此不会增加体积及重量，故不会影响到电动车的设计。
另外，根据本发明的实施例，可应用于各种不同类型的永磁电机，例如直流无刷电机及直流有刷电机等等，故应用上极为广泛。
再者，根据本发明的实施例，永磁电机装置的结构设计简单，因此可以在不大幅增加成本的情况下达到所欲达到的功效。由上述可知，本发明实具进步性的专利要件。
