Homemade Electric DC motor for school project

Click For Summary

Discussion Overview

The discussion revolves around the challenges faced in building a homemade electric DC motor for a school project. Participants share insights on construction details, operational requirements, and troubleshooting steps related to the motor's functionality.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Homework-related

Main Points Raised

  • One participant suggests that a commutator might be necessary for the motor to function properly.
  • Another notes that simple motors typically require an initial manual spin to start, and mentions that the direction of rotation may depend on construction details.
  • A different participant describes their experience with an electromagnet motor that is not spinning and invites others to share pictures and instructions for better assistance.
  • There is a suggestion to review similar threads for additional insights and potential solutions.

Areas of Agreement / Disagreement

Participants express various challenges and insights, but there is no consensus on a specific solution or approach to the problem. Multiple competing views on motor functionality and construction remain present.

Contextual Notes

Some participants highlight the importance of construction details and initial conditions for motor operation, but specific assumptions and dependencies are not fully explored.

Homework Statement
I made a simple electomanget motor, I am using copper magnetic wire with 120 turn on each side of a iron nail, this issue I am getting is that it's is not spinning. Specifically the iron nail is always attracing to the permanent magnets and is not giving the repulsion force needing it to create the spin.
Relevant Equations
No equation needed
No solution given

Sounds to me like you might need a commutator. Google might be a good next step.
"I tried to build this thing and it didn't work". Isn't a question, and if it was, it would be really hard to answer.
 
Also, those simple motors WILL NOT [/size] start on their own. You have to give them a good spin to get them going. Depending on construction details, the may have a preferred direction of rotation, however most wil spin either direction.

Reading other posts listed below in the similar threads section may help too.

Welcome to PF.

Once you have looked at the similar threads below, if you still have no luck, attach a picture of the motor you built so we can see the detail, and give us a link to the instructions you have. That will make it easier for all.
