pulse motor Working video and info

[casman1969]

Adam,

I have found this pulse motor to be the most interesting one to build and I'm in the process of doing just that. I REALLY like the way those coils are being wound and for now just one question. What is the optimal ckt for a three drive coil system? Will have more questions later but I'm still doing the mechanics on a 20" disk of aluminum ( 1/4" thick) two disks and whether to go horizontal with a magnet to float the load or Vertical and deal with the bearings losses. But it's the ckt that's most important right now. Just want to be sure this part is RIGHT the first time.

Thank you for being here,

Carl

@tropes,

Yes I do wind my own coils, I have never used a manufactured coil. I have used attraction and repulsion for my setups. I find that placing the magnets close together, you are able to use both of these properties. I only use one transistor, no reed switches or hall ic's.  The cap or battery is connected directly to the transistor's collector and emitter legs ( one diode is needed inline on the emitter side).  I am familiar with the adams motor, although I have never used his exact setup. And by crap bearing, I mean shitty.   My bearings are flange bearings, I removed all the grease with acetone and frequently run acetone thru the bearing to keep it free of buildup and debris.

Hi Jason
I would like to see a circuit diagram to understand how power is directed to the coil without a switch (no commutator). Do you use shitty bearings because of cost?

I use the flange bearings because they are durable. Here is a quick pic of the general setup.

Hi Jason
I have added color to the circuit from battery to driving coil.
Which is positive and which is negative? Where is the cap. and diode?
