Thread: Black Vent Motor Tutorial (Part 1)

Tweet

Sorry, one more question I forgot to ask before. What matters more the vDC or mA. I know my local Science Surplus had some higher vDC with lower mA.

The best way I understand this is the following....(and someone correct me if I am wrong)...

These motors are DC therefore they need to have a DC power source. I made the mistake of trying to hook up one, when I first starting using them, with 12vAC and it didnt work at all. Then I tried to use a 12vDC with minimal (I think 100-300mA, somewhere in there) power, and I could tell the motor was trying, but still would not turn, with no load. That's when I "discovered" if you will, that I needed more mA's. From there I went to the 12vDC and 1.2A, and it works great!

Bottom line...I think it HAS to be 12vDC, and at least more than 300mA. One more thing...DC motors will only pull the mA's that it needs to run, so when I say "at least 300mA" that is what I mean. It can be higher, i.e. 750mA, 1.0A (or 1000mA) and so on. The motor will only pull what it needs.

I hope this helps you "killa" and if you have more questions, just ask...

I've had these motors running with 12 volts DC, 100 milliamps up to 1 amp with no problems.
I would recommend using at least a 500 milliamp adapter. That's what I use on most of my props using the vent motor.
