                                                  发布日期:2022-04-11

                                                  首先,相对于有刷电机,无刷电机具有以下优势:

                                                  (1)免去碳刷的维护保养;

                                                  (2)抗无线电干扰;

                                                  (3)减少失磁故障。

                                                  至于是无刷好还是有刷好,只能说各有千秋,这要根据您的使用情况来选购,有刷电机是依靠碳刷和转子上的整流子的直接接触实现电机运转。它的优点是功率较大,爬坡能力较强,成本较低,其缺点是因碳刷与整流子直接接触且高速相对运动,一般1~2年要更换碳刷,无刷电机是针对有刷电机以上缺陷开发出的直流电机,其噪音低、使用寿命长、电耗较小,控制器的性能要求也高。如若作为备用电源来使用建议使用无刷电机,避免碳刷磨损过快,不能及时更换。
