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！

阿莫论坛20周年了！感谢大家的支持与爱护！！
你熬了10碗粥，别人一桶水倒进去，淘走90碗，剩下10碗给你，你看似没亏，其实你那10碗已经没有之前的裹腹了，人家的一桶水换90碗，继续卖。说白了，通货膨胀就是，你的钱是挣来的，他的钱是印来的，掺和在一起，你的钱就贬值了。
