SPG电机SPG交流马达具有高启动扭矩，因此，启动上的性能良好。并且，以AC马达同样的尺寸，DC马达具有同样的输出功率，而且马达的功效要更好。此外，DC马达在速度控制上要方便很多，并且也容易改变旋转方向，还能够紧急刹车. 如果转子绕组中的电流不是由定子旋转磁场感应的，而是自己产生的，则转子磁场与定子旋转磁场无关，而且其磁极方向是固定的，那么根据同性相斥、异性相吸的原理，定子的旋转磁场就会拉动转子旋转，并且使转子磁场及转子与定子旋转磁场“同步”旋转。这就是同步电动机的工作原理。毫无疑问，同步自然控制起来更方便一点。

目前驱动电机主要分为直流电机、交流电机及轮毂电机等；其中，直流和交流电机又可进一步划分。目前行业对交流异步电机、永磁同步电机及开关磁阻电机关注度较高。通过对常见的几种电机进行比较分析可知（见表1），永磁同步电机具有效率高、转速范围宽、体积小、重量轻、功率密度大、成本低等优点，成为纯电动乘用车市场的主要驱动电机。 从行业配套来看，新能源乘用车主要使用的是交流感应电机和永磁同步电机。其中，永磁同步电机使用较多，因其转速区间和效率都相对较高，但是需要使用昂贵的系统永磁材料钕铁硼；部分欧美车系采用交流感应电机，主要因为稀土资源匮乏，同时出于降低电机成本考虑，其劣势主要是转速区间小，效率低，需要性能更高的调速器以匹配性能。 随着新能源汽车市场的迅猛发展，驱动电机市场空间潜力巨大，吸引了众多企业和资本的进入。国内外典型驱动电机企业的永磁同步电机产品情况如表2所示。整体来看，我国驱动电机取得较大进展，已经自主开发出满足各类新能源汽车需求的产品，部分主要性能指标已达到相同功率等级的国际先进水平。但是在峰值转速、功率密度及效率方面与国外仍存在一定的差距 永磁同步电机在生产工艺方面的难点是制约大规模配套乘用车的重要因素。因为永磁同步电机生产企业缺乏产业化的积累，国内企业生产不良率较高，无法达到乘用车企业的不良率要求，尤其是随着纯电动乘用车市场规模的扩大，十万级的年产量给永磁同步电机带来了巨大的挑战。 那就会在主电机增速后，出于电路中的导线和元件接触不良使电流敏捷加强，而惹起维护性的停机，当调速电机运转速度过低时，出于主电机的任务电流较小而无法发作气但愿速逐步下降以致停机的状况，然则，当调速电机升速时。对普通异步电动机来说，变频电机设计时主要考虑的性能参数是过载能力、启动性能、效率和功率因数。而变频电动机，由于临界转差率反比于电源频率，可以在临界转差率接近1时直接启动，就等闲使电气元件发烧，接触不良，除此以外摩擦片中的那部分杂质加强了分离聚会器在不吸合上作时的摩擦负荷和损害，这个时刻，电气元件由于接触不良而不吸合，使其温度升高，制动电磁分离聚会器线圈的绝缘便会过早受到损害，致使最终被销毁。因此，过载能力和启动性能不在需要过多考虑，而要解决的关键问题是如何改善电动机对非正弦波电源的适应能力。SPG电机产品规格:6w ~ 200w 输入电压：交流：110/220V单相, 220/380V三相,直流：12V~110V 减速比:1:3~1:200 标准尺寸,方便维修更换 CCC,CE , UL ,CSA,ISO-9000,IEC,JIS等认证通过 。 产品种类：交流电机(感应电机、可逆电机、调速电机、电磁刹车电机、端子箱电机、调速带刹车电机)；直流电机；无刷直流电机
