Robots Motor

rajkiransingh
rajkiransingh over 5 years ago

I have designed a bot in which motors are used at different distance.

Controlling part of the motors are kept one side and rest of the 15 motor are connected parallel to each other.

The gaps between the each motors is 60 cm like wise there are 15 motors connected.

 

Now the problem is the first few motors are rotating at same speed and gradually the next motors are rotating at very slow speed compared to the first motor.

 

Now please guide me how to over come this. I think there is a drop in voltage as the length is increased. How to distribute the equal voltage irrespective of length of the wire.

Approximate length of wire is 8 meters to 10 meters long.

    If you run separate power and ground wires to each motor it will mostly eliminate the problem.

    If you also make all wires the same length, all motors will get the same voltage.

    An alternative is to use heavier gage wire connected the way you have it now. If the wire gage is heavy enough, the accumulating voltage drop will be negligible.

    There are online calculators that can help....
