Sharing ideas on how to make a more efficent motor using Flyback (MODERATED)

Get rid of all steel

Silicon steel/soft iron is the best material to use in low frequency applications.

If we have put in the same amount of energy in each case,but we capture less electrical energy out from the bucking coil's-where did that lost energy go?-it cant just disappear.  I also stated that two magnets in a bucking configuration triples the pull force of that of 1 magnet on a magnetic material that is close by. Is it conceivable that this lost inductive kickback energy from the bucking coils was transformed into mechanical energy by way of a larger/stronger magnetic field produced by the bucking coils?.

Hi Brad,

Unfortunately I forgot to consider in my answer yesterday that if  in the not bucking coils mode you asked, when the resulting inductance would be say indeed higher than in the bucking mode, then the coils AC impedance would also be higher, thus to insure the same input current, the input voltage should be increased and this would involve higher input energy.  So we need to consider this when we wish to compare the bucking coils with the not bucking coils performance and answer your question.

I do not think that transformer laminates you would use for the tests will become magnetized in time (unless very strong peak currents would be involved on the long run).

Hi everyone,

as promised here is v.2 of the Bucking Field Reluctance Motor. You may be surprised at what happened.

Good link bait headline! I'll be watching tonight.

Here is the first part of the bucking field motor test bench build.
Sorry about the small product review lol.
