Controller circuit for Hilden Brandt motor needed..

Here is a new video. This time with bigger magnets, to see what that does.

When I play the small version of the new movie it looks like a screen saver or something.

Hi Steven,

Enjoying the show.
If you haven't seen patent 6369479 FIG 26 allready, this study can save you a lot of time and maybe some magnet money. It is a chart comparing current, separating force and magnet size for the Sumo magnet switching unit.

Another great video. Thanks.

I don't know how you have made the coil windings of your motor but I have been posting this patent here and there on the forum. I think it may have some relation to the motor for a better coil winding strategy.

I was chatting with Erfinder about the motor and your videos and he said it is basically a reluctance motor with a magnet, which is super neat. You may look into reluctance motors and controllers on Google. Erfinder says the problem with points (or hall effect for that matter) is that the faster you turn the motor, the less contact time you have on the points because they are directly related to the rpm.

Based on that observation, I am thinking that as the rpm increases the motor is less and less riding on the contacts to drive the motor and more more time on the open, thus probably changing into a generator. This will depend on the rotor materials and if there is any north south magnet in the rotor since I do not know the materials. Actually the rotor has to have some magnetic affinities otherwise it would not turn.

Now if this is the case, and Jacks motor (and your current build) may actually be half motor/half generator, this may explain why Honks circuit was not operating to spec. Standard reluctance motor controllers are available on the market and may be a good option to consider.

Here are some links;

Looking at your build, I am also thinking that the valve may be a good method to produce a drive motor I had posted way back on the forum located here: (Look at the last image animation).

If such a valve can generate enough magnetic strength to propel a metal weight towards the left, this may be a good avenue to make a drive motor with much more torque potential using gravity. Such a drive motor would do away with BEMF and it would be simpler to capture the coil flyback since each coil would be off for a longer portion of the cycle.

Anyways, keep up the good work.

Hmm?
Here it's fine besides the lower quality.
So use the bigger one instead.
