Controller circuit for Hilden Brandt motor needed..

[utilitarian]

Steven, it looks like you put a lot of work into that test, thanks.

I have another general question, and I am not an expert in things electrical, but this is what I am having trouble grasping.

It seems like the whole purpose of the motor is to take electricity, convert it to mechanical energy, and then convert the mechanical energy back to electricity.  That seems wasteful.  If there is something to be gained from redirecting the magnetic flux like that, can't there be a way to just harness that surplus without having to convert the electrical to mechanical and then back again?

Hi Steven,
Let me congratulate you on a most impressive video, your systematic approach and the marvelous craftmanship of your work.
Your motor is similar to Jacks' but not a replication as your magnets are not in his position and your rotor is very different.
Please don't take this as criticism, for I admire your workmanship. Keep it up and again, congratulations.

Carl

Hi all,
Here are the motor tests:

Let me know what you think.

Hi do you think problem is the switching frequency? since in previous video in "steady state" the valve works as intented

Hi Steven,

Well, Great job, Carl said it all, so I'll not run on.

I am confused about your lack of increased torque. Your magnetic switching unit is closer to the Sumo motor, you can see the performance charts here if you haven't before:

There main motor is a hub motor (example at bottom of page), so the stator and rotor are inverted. But they have four magnetic switching units instead of two. That maybe where you are losing some of the torque.

Hey Jack,
Tried to send a PM but they must be having problems.
Just wanted to say Hey and wish you all the best as you are a true Hero.
You are in my prayers.
