How to build a pancake DC Motor?

Click For Summary
SUMMARY

This discussion focuses on building a micro pancake DC motor, specifically requiring 32 motors connected in a line powered by a single supply. The motors should be approximately the size of a dime. Participants suggest purchasing a miniature pancake motor, such as the Maxon 6mm Pancake Motor, and disassembling it for insights. Historical context is provided by referencing Richard Feynman's challenge in 1960 to create an electric motor smaller than 1/64" in size, highlighting the advancements in miniaturization.

PREREQUISITES
  • Understanding of micro DC motor specifications
  • Familiarity with electrical circuit design
  • Knowledge of power supply requirements for multiple motors
  • Experience with miniature motor assembly and disassembly
NEXT STEPS
  • Research the specifications and applications of the Maxon 6mm Pancake Motor
  • Learn about parallel power supply configurations for multiple motors
  • Explore techniques for assembling and soldering miniature components
  • Investigate the principles of brushless induction motors and their miniaturization
USEFUL FOR

This discussion is beneficial for hobbyists, engineers, and inventors interested in robotics, miniature motor design, and prototype development.

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 http://www.motionshop.com/pr/Maxon-6mm-Pan.shtml

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.
