发帖数: 925 | 1 google了一下，local 的店不多，上ebay买的话servo motor和driver都是分开卖的
貌似不好配对，而且接线也麻烦。有没有哪位能提供一下便宜的（二手最好）
电机+伺服驱动的信息？
看了一下ebay上的，安川Yaskawa的比较多，但是接线麻烦
Sanyo的也不少，貌似接线简单一点
而且我想用110V 2phase的不知道好不好找。
也找 distributor询价了，看看明天有没有什么答复 |

发帖数: 301 | 3 Swiss motors are good. They are many of them to choose from. You can get
pretty cheap ones from ebay. You want look at its specs to match what you
want.
The driver you mean, I think, is servo amplifier.
AMC's servo amp is good and cheap. www.a-m-c.com. 12A8 is good for regular
brush pwm motor
Then, of course, you need a DAQ. It could be cheap or expensive depending
on your application.
The motor is not going to take 110v. The amp will. It is usually 2 phase,
if you are not building som

发帖数: 925 | 4 我看到Advanced的Amplifiers好像在ebay上卖的挺便宜，而且他的网站上有
电机选型，非常感谢你的推荐，只是不知道AC servo motor买哪一家的
以前都是用松下的，不过美国好像松下的卖的很少。
我主要是做电机办闭环控制实验（motion control），或者加上parker的router玩玩，
负载不会很大，所以对电机的要求是越便宜越好
是不是不管安川还是三洋或者rockwell的电机advanced的都能接上？
以前都是成套买，还没分开买过

发帖数: 301 | 7 They have to match. But it is easy to have a match. For example, the 12A8
will drive a brush motor with PWM. Then you need to look at what is the
current range and voltage range. You also need to know what the output
voltage range of your DAQ is. You want to use the full range of the DAQ to
have better resolution. I forgot to mention encoders. To have a closed
loop control, you have to buy a encoder for the motor. Sometimes the motors
are selling with encoders. A cheap potentiometer may
