Motors.
« on: October 22, 2015, 09:16:52 am »
I use battery powered motors. Over time the batteries run out of power and the motor slows down and looses power. Then I recharge the batteries and the motor goes back to full speed and full power.

Are there any similar problems when using the motors that plug into the wall?

On the topic of motors, does anyone have a good use for the spring motor?

The 12V motors  don't get slower over time, they might wear out when using 24/7 for months, but then again, which motor wouldn't wear out with that kinda usage?
As to the battery problem, I started modifying my red battery pack motors so that I can plug 'em into the wall, so that they won't get slower after time and I don't have to recharge all the time.

As for the spring motors, I guess you could make some kind of launch mechanism.

Was it difficult modifying the red battery motors or did you put something like a alligator clips on it?

I did basically that, only that I soldered the wires to them in a way so that i can still use batteries, if desired.

I have one of those outlet powered motors, I've had mine for two years, and it is still running strong. I don't know of any ways to make battery motors any better without severely modifying the box.

You could use spring motors for a flywheel launcher like Austron did at brickworld?

Just in case you didn't know, the reason they slow down is that as the battery gets used the fuel cells in it become less effective and the voltage drops. Each AA is supposed to be 1.5V, some come at up to 1.7V.   


If there's two AA batteries, a 3V power supply would work great.

I was thinking of buying a 12v motor that plugs into the wall but it is really expensive for it + the adapter!

Oooh... the times where you could buy them seperately, in a normal store <3 I think it was 2000 or so...

My K'nex ball machine at The Works Museum is powered by 3 plug-in motors, and it has been running 8 hours a day, 7 days a week, for over 2 years now. So far, the motors themselves have yet to burn out or slow down. However, the nylon worm gear and white gear really take a beating. I have to replace them every 6-12 months.
