求教, 新买的电机,控制板和电源!

大家好,我前两天在ebay买的电机, 控制板和电源(买的时候他说是nema23, 但电机上面标的是57BYGH408-06, 控制板是基于TB6560的3轴控制板, 电源他说是24v 6.3A 结果给我邮来了个36v 9.6A的), 经过测试最多只能驱动一个电机, 偶尔可以驱动两个但是力量小到用手都能让他停止!

请大家看看这样的配置可以吗， 为什么只能驱动一个电机呢， 是电流不够吗， 还是什么情况？ 我是新手啊，请大家多多帮忙！谢谢了！

下面是参数和图片！

我的电源也是跟你一样的，好像运行挺正常的，驱动3个57的3A电机

可以使用德国TRINAMIC公司的TMCM-351集成了三轴57步进电机的控制+驱动+I/O与一体，带有防丢步失速检测功能。

你这个又没购买途径，报价都没有，说了等于没说

这个驱动器应该是没问题的。按照这个驱动器厂家的技术员介绍。这个取东西最好是配套24V 14.7A的电源。当然不排除驱动器已经损坏

不过合并的驱动器，电流相对分离的驱动器来得小，而且干扰要大。
