HP 6033A电压下降

问答对人有帮助，内容完整，我也想知道答案 0 嘿所有，让我首先说我是一个完整的新手（我是一名机械工程师：/）。我已经阅读了电源手册，我不明白为什么会这样。基本上我试图用电源控制一个简单的直流电机。 12伏特和330毫安，完全在机器的范围内。 OVP设置为22.所以我已经用GPIB和前面板手动编程了机器。我设置了我想要的一切，前面板读取12伏特和0.33安培。然后我翻转开关连接电机。电机运行大约半秒钟，电压就会下降。电流保持不变但电压降至0.3 V.旋钮或VSET gpib命令的任何扭曲都不起作用。显然我对电源的工作原理还不太了解，但这似乎是一个容易出问题的问题，并且没有任何意义可以解释为什么电压会下降。任何帮助将不胜感激！编辑：theSeavenger于2012年3月24日下午1:28 以上来自于谷歌翻译以下为原文 Hey All, Let me start by saying I am a complete novice at this (im a mechanical engineer :/ ). Ive read the manual for the power supply and I dont understand why this is happening. Basically I am trying to control a simple DC motor with the power supply. 12 Volts and 330 MA, perfectly within the limits of the machine. OVP set at 22. So I have programmed the machine both with GPIB and on the front panel manually. I set everything how I want it, the front panel reads 12 volts and 0.33 amps. Then I flip the switch to connect the motor. The motor goes for about half a second and voltage just drops on the power supply. The current stays the same but the voltage drops to 0.3 V. Any twisting of the knobs or VSET gpib commands do nothing. Obviously I do not know enough about how power supplies work but it seems an easy problem and it does not make any sense why the voltage would drop. Any help would be greatly appreciated!

答案对人有帮助，有参考价值 0 对于这样的轻载（330mA），6033A（0-20V / 0-30A）应该是过度消耗。我怀疑，6033A是以恒定电流（？）运行的。您已指示电机运行1/2秒。然后输出电压降至0.3伏。这表明恒定电流操作。电机连接，输出电压为0.3V; 是CV熄灭和CC LED照亮？如果是这种情况，6033A肯定处于恒流操作。将CC限制增加到更大的值将阻止6033A进入CC操作。 PeterW 以上来自于谷歌翻译以下为原文 The 6033A (0-20V/0-30A) should be an over-kill for such a lite load (330mA). I suspect, the 6033A is operating in Constant Current(?). You have indicated that the motor runs for a 1/2 sec. then the output voltage drops to 0.3volts. This suggests Constant Current operation. With the motor attached and the output now at 0.3V; is the CV led extinguished and the CC led illuminated? If this is the case, the 6033A is definately in Constant Current operation. Increasing the CC limit to a larger value will prevent the 6033A from going into CC operation. PeterW

I believe you are going into CC mode. What you are seeing in the beginning is the power supply is in CV mode when you start and then takes about a half second to go into CC mode. DC motors tend to look like capacitors at start up so they have higher inrush until they get up to speed. You may need to set the current much higher until the motor is up to speed then you can lower it to its running current. Raclegg
