Inwheel Go-Cart Design Help - Ideas for Precise Control

[Squirt8500]

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?

 

[FredGarvin]

I'm sorry, but you still lost me. These coils would be above and beyond the existing rotor and stator?

 

[Squirt8500]

yes the coils would be on the stator
