Discussion Overview

The discussion revolves around the design of a go-cart utilizing in-wheel motors, specifically focusing on the implementation of electromagnetic "flaps" for precise control of acceleration. Participants explore the technical aspects of actuation and control mechanisms, including the use of sensors and resistors.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant proposes using electromagnetic "flaps" to control acceleration in a go-cart design, inspired by a Volvo concept.
  • Another participant requests clarification on the term "flaps," suggesting that the initial description lacks specificity regarding their function and actuation.
  • A participant elaborates on the design, describing the flaps as coils of wire that would be placed side by side on a smaller wheel, activated by the presence of a magnet.
  • There is a question about the feasibility of using a variable resistor to control the speed of the cart.
  • One participant expresses confusion about whether the coils would be additional components beyond the existing rotor and stator setup.
  • A later reply confirms that the coils would be integrated into the stator design.

Areas of Agreement / Disagreement

The discussion contains multiple competing views regarding the design specifics and functionality of the proposed electromagnetic flaps, with no consensus reached on the best approach or the clarity of the initial proposal.

Contextual Notes

Participants have not fully defined the operational parameters or the specific mechanisms for actuation, leaving some assumptions unaddressed. The discussion also reflects uncertainty about the integration of the coils with existing motor components.

I have an idea for making a go cart with a in wheel motor, same idea as the
volvo recharge: http://www.alt-energy.info/wp-content/uploads/2008/03/hiw_hybrid_infog_485.jpg
My idea is to have electromagnetic "flaps" that can be turned on and off and i was wondering how i could turn them on and off precisely so i could control the acceleration and other variables
I was thinking about using a hall sensor but i couldn't control very much about that
so any ideas would be great thnx

You have to define what you are looking at. The term "flaps" isn't very helpful. The picture you show simply shows an electric stator and rotor combination places in a wheel hub assembly. That's all well and nice, but very low speed. Describe what you are talking about specifically their use and how they need to be actuated.

The flaps that i am talking about are a coil of wires, laminated, and i will have a lot of them.
then i would place them on a smaller wheel side by side.
they need to be actuated so that if there was a magnet that is before it the coils will turn on and when it passes it will turn off, i would need to control the actuation of the coils so i could accelerate.

would a variable resistor be able to control the speed of the cart?
 
I'm sorry, but you still lost me. These coils would be above and beyond the existing rotor and stator?
 
yes the coils would be on the stator
