布列松兄,
我的电机是5v的,看视频你的好像和我的是一样。可是easydriver驱动电压要7v起。你就是接的5V ....
转了!我读了一下easydriver网站的说明。那哥们保证说7-30的输入电压是给电机提供“电流的”。和电机额定电压一点关系都没有。我接上9V的试了一下,没问题的。 只是电压越大可以转得越快?下面原文:Q1) My motor says it can only take 2.1V at 2A. Will the EasyDriver (running from up to 30V) blow up my motor or damage it in any way? A1) Nope. You're safe. Motors are specified with DC flowing through their coils. But what we are concerned with is maximum current. The voltage spec of the motor doesn't really matter, using the EasyDriver. (Or any chopper driver, for that matter.) The EasyDriver will ramp up the voltage to the coil until the _current_ reaches the maximum set with the pot (max of 750mA). Then it will cut the power to the coil until the current dips down again, then re-apply power, over and over again, about 20,000 times per second. Any motor that's rated for 150mA/coil (or more) will work with the Easy Driver just fine, no matter what it's voltage rating. Note that if your motor is rated for less than 750mA/phase, you should adjust the current set pot on the EasyDriver to dial down the maximum coil current to match your motor. 来自: iPhone客户端 |
