Thread: Emergency-12VDC motor control

Tweet

Okay, I'm converting a Little Tykes Jeep into a prop (right now it's a christmas train). At halloween I'm going to make it a haunted train.

I used a deep cycle marine battery to drive the train. This is 12VDC. The thing is WAY too fast. I need to slow it down.....WAY DOWN! What can I use that is cheap. I tried to use a wall light dimmer switch but it won't recognize the voltage since it is DC.

What can be used that is cheap

Maybe the easy way is to add more cars to the train. If not you go go on Ebay and look for a speed control for it. If you still have the speed control for the car you can use that. You can slow it down that way.

I'm no electrician (I think I start every tech reply this way! ) but I'd think you could solder a couple resistors into the line coming from the battery which should stop down the power level. Now this wouldn't be variable but it might work to get you to a lower constant power level.

Not a really good idea. You would need a larger size resistor due to the current. The heat coming off those resistors would be great.

I don't know if something like this controller board would work or not:

Try the website www.kitsrus.com . Look at Kit 67 and Kit 166 (bidirectional).
They are well-designed and easy to build. I use Kit 67 with 12-volt wiper motors.

Like I said.... I'm not... oh nevermind.
