Discussion Overview

The discussion revolves around the design and functionality of a motor utilizing strong electromagnets, specifically addressing questions about operational mechanics and efficiency. Participants explore theoretical and practical aspects of motor construction, including electromagnet placement and energy loss.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether it is necessary to fire the electromagnets past top dead center or if leaving the power on is sufficient.
  • Another participant raises the concern that higher force from more turns of wire may lead to lower RPM, particularly in relation to the electromagnets positioned at each end of the motor.
  • A different participant shares their experience attempting to build a similar motor, noting significant energy loss when the rotor is not in proximity to the magnetic field, suggesting the need for multiple magnets or a circular configuration.
  • Concerns are expressed about the proportions of the motor design, indicating potential precision issues and inefficiencies in generating a magnetic field over a large area.
  • One participant expresses intent to order additional electromagnets and considers making curved ones for their design.

Areas of Agreement / Disagreement

Participants express differing views on the design and functionality of the motor, with no consensus reached on the effectiveness of the proposed configurations or the necessity of specific operational techniques.

Contextual Notes

Participants mention limitations related to the availability of parts and the precision of homemade components, which may affect the performance of the motor design discussed.

The diagram is for a motor using the really strong electromagnets I found on ebay they have 500 pounds force even when 1/4 inch away


1. Is there a need to fire the electromagnets past top dead center or can you just leave the power on.

2. If the force is really high then would more turns cause lower rpm and would that apply to electromagnets on each end as shown in my motor.

Sorry, dude, but your artwork is incomprehensible. This seems to just be an end-run around the same stuff that you've been posting before. Study up on electrodynamics yourself if you're not willing to accept the viewpoint of the experts.
 
you can't move a motor like that... stupidly i did try to build a homade motor like that... anyway, it loses a lot of energy in half a circle without magnetic field present... at least with the poor parts i got... the electromagnet is usful only when when the far edges of the rotor are really close to it.

so either you put several magnets round the rotor, or you create a circular magnnet with your electromagnet...

oh, and the proportions of you motor are quite odd.. that would make a lot of precision problems, plus filling a large area with a magnetic field.

i myself not long ago tried to make a motor myself, its all set, just one problem still in the way, and the lack of parts( i use hommade parts) prevents me from finishing it... but I am sure ill find something sometime...

Thanks

Im going to order several from ebay and maybe make some curved ones.

Thanks to all for your support.
