Pulse Motor with Recirculating Current Feedback Circuit

A test and demo of a small 16 coil pulse motor with feedback circuit. It spins at ~3,200 rpm with no load attached and about 2,100 rpm with a six inch fan attached. Uses approx as little as 8 watts to run and has the same characteristic that I've showed before with no increase current draw to the motor when the output shaft is loaded. What I found interesting with this circuit design is that while the current going to one half of the motor is only about ~400-600 milliamps while running is that the temperature of the motor core is so high. To me this shows that there is a circulating current that is much higher than the input current.

Can you post a circuit diagram here for novices to see what the setup is.

Thanks

Not at the moment due to agreements that I've made. But hopefully very soon. Plus I'd rather post the best working circuit possible, which takes time to setup and test etc. I hope you will be patient with me.

I notice you use a reed switch. Do you attach a relay to that or did you make a transistor circuit? I found that the transistor type circuit doesn't "close" or "open" completely so the torque is reduced. Same goes for a solid state relay, less torque.

I'm passing the current right through the switch. I'm not to sure about the relay, but at least with the transistors I use, they have to be switched on the negative side of the coil. I agree though, mechanical switching is fastest. Each have their respective pro's and cons.

I was wondering if you ever thought of placing the coils in the middle of the motor and place the magnets on the outside. If you do this you use the NORTH/SOUTH poles of the electro-magnet and the NORTH/SOUTH poles of the spinning magnets. It seems like a waste to not use the opposite side of the electromagnet. Let me know what you think.

Yes... indeed good thinking on ya... btw, i don't post everything I make. ;-)

How are you creating the plastic structural components?

[condor2224]

I think your coils heating is due to the number of turns on the coil. If you increase the number of turns on the coil by a few hundred this should reduce the coil temp and become more stable.

Nice machine! SO do this overunity?
