How do I do RC Car circuit modification?
I want build an rc car from scratch (sort of). I bough a 24V 350W DC motor that was on an electric scooter. Ha! I will buy the receiver, a radio controller, and some sort of frame. I just want to know how I should modify or recreate the circuit board. Also, what type of battery string(s) should I have connected? I guess I need some sort of speed controller.
Anybody out there?
Lots of people out here!
But maybe like me, they are thinking you are biting off more than you can chew.
Somewhere on the internet I saw a design for a high current speed controller. I think it was on a university site, designed by a student as a project.
Typically, such a circuit would draw its input from one of the servo connectors on the receiver. But at 24V., it would probably pay to use a separate 4.8V receiver supply.
Also typically, for 24V., you would need a series connection of 20- 1.2V cells, or 2- 12V Gel cell batteries. Either way, the cells or batteries need to be able to deliver the required current for the motor. That’s about 14.5 AMPS!
