motor voltage

[jagman62]

Hi,I wonder if anyone can tell me the voltage of the motor in the airsoft guns in heng long tanks.To test a gun mechanism I wired it to a 7.2 volt battery & it went of like a machine gun so I am assuming that the control board reduces the voltage,but to what?

Hi if its any help when I built my abram's, I used a dc voltage reducing circuit board off e-bay (£3 including P&P) that took 6-12 volts input and gave both a 3 volts and a 5 volts output at 2amps. The gun runs on either. (due to the modern tanks having a auto reload system I use the 5v for the speed, and the 3v side I use for my lighting circuit and also the lazer aiming point for the main gun.

hi,thanks for the quick reply in answering my question,it was just in case I needed to order a replacement motor for my tank.

What 'Voltage Reducing Board' did you use hawkeye3guns ?.... Please can you find a similar one on ebay and link across to it ?

something like this will do it

Hi I just put a search in E-bay for a DC to DC step down board and then pick the one that suited my application and voltage requirements or as Ian has posted you can use an item like he suggested.

I just add I've have had a few voltage regulators fail on me in the past. Not certain if bad batch or I was running too much current through them (using on modified smoker). So might be best to pay attention to your running current and make sure your voltage regulator is double it to be extra safe.

I checked mine, it was indeed 5V. You could use a 5V regulator as suggested above but personally I prefer to keep things 'off-the-shelf' as it were. I am building a brushless tank with two speed controllers, the Battery Eliminator Circuit on speed controllers generally give 5v, one speed controller BEC runs the receiver and the BEC on the other ESC provides power for my gun and convoy lights etc.

If you're not using speed controllers something like this will provide 5V without custom electronics.. http://www.hobbyking.com/hobbyking/stor ... ouse_.html
