I need to build a micro pancake DC Motor. I actually need 32 of them connected in a line with one power supply. The motors need to be about the size of a dime. Could someone write me a how to guide on how this can be done. It is for a prototype.

You might buy a miniature pancake motor and take it apart. See

In 1960, Feynman (the physicist) offered a $1000 prize to the first person who could build an electric motor less than 1/64" in size. Someone did, and it was sitting in a glass case in the Cal Tech Physics Dept. for many years. It was a 3 phase brushless induction motor. It was under a microscope so you could watch it spin when you pressed the switch.
