The yoke of the rotor and a simulation with FEMM

Here's an other model of the Quadrupole motor.

In this picture, I have design the yoke to attach to the rotor assembly. Just need to add the coils and hardware to finish the job.

Below, here is movie of the FEMM simulation that was perform last October.


The simulation shows the flux orientation of the segmented rotor going in and outward to the stators.

Welcome the OpenVolta Blog - my first post!

On this blog, I will publish my own designs of electric motors and generators as part of the OpenVolta project. The results will be published as well as CAD drawings

So everything you see here is open source, open motor, open generator... An open technological blog. My way to share to you might work that will hopefully be helpfull to anyone that would like to built their open electric motor or generator.

Why not patent my work? I could and I might... One day I supposed. The real reason is that I don't have time to go through the hassle of patenting a project and spending hundreds or even thousands of dollars, in patent and then to protect it. So why not share. I'm no genius and just hope that what I propose will serve someone purposes. If I achieve this, then thank you to myself.

Time is running out. We need to unite our forces together and start cooperating, globally, to make this world better. Nice cliche will you say! Yes but again, it's true.

If you would like to have a bit more information about the work that I have done, I invite you to visit the openvolta website for the time being until more information about my developments are published.

What I can tell you is that I'm focusing much of my efforts on the Quadrupole motor/generator. This a new motor design. As you can see below, the structure of the Quadrupole motor/generator is a single rotor having a quadrature magnetic field, sixteen in total and a dual stator (inner and outer). This type of rotating machine as the rotor set between two stators and the flux is radially distributed inward and outward of the segments of the rotor. The rotor’s topology has an arrangement of permanent magnets (PM) installed circumstantially and tangentially to the segments so that the PMs are such that the adjacent pole have the same identical polarity to concentrated the flux within the segments. The segment retains most of the flux.

 
This rotating machine is 280mm diameter and only 38mm depth and at 100 amps, it will output up to 35 Nm and 18kW at 144Vdc.

I have also publish a paper. It is available at the openvolta website.
