I have also read that pulsing a dc motor will greatly improve its efficiency and I can c how but has anybody had success doing it.  I haven't seen it yet.   Thanks

Pulsing a DC motor will NOT increase it's electrical P/in to mechanical P/out ratio.

It is the biggest cause of mis-measurement I have found out there to those who believe they can

hi..   markdansie & tinman

this is about pulse DC.  both of you must be familiar with pict bellow, what do you think?
sorry, i am out of topic.

This is part of the story and not the whole thing.

Bedini is full of pulsing, as is Bob Boyce's water fracturing technology. Chas Campbell has mechanical pulsing. Pulsing is all over the place but be mindful of a need to maximise through resonance where appropriate.

So has anybody thought of using a servo or stepper motor to generate with.  It seems to me like there is not much confidence in the chas campbell design even with several replicas on YouTube supposedly producing power.  Is the key to the system matching the rpm of the two motors or could you have different wheels at different rpm and use them to take the shock of large loads and maybe use one way clutch so if they slow down to much it will cut the generator side and recharge the wheels again?

Don't get all confused about pulsing. There are classical "pulse motors" which work by sending a pulse of power to a rotor, with the pulse being timed to the rotor position somehow; these motors are usually not particularly efficient but they are loads of fun to play with. Examples are the Bedini-type motors and the MHOP motor, Steorn's eOrbo, and so on. These motor drivers usually operate at relatively low frequencies with fixed pulse width (duty cycle) and the frequency is directly related to rotor speed.

Then there is PWM, pulse width modulation, which is in fact an efficient way to control the speed and output power of ordinary DC brushed motors, without regard for rotor position. These drivers operate at higher frequencies and with variable duty cycle (pulse width) and the frequency is more or less independent of rotor speed. A variation of the basic PWM scheme, usually with rotor position sensing, is used to drive brushless DC motors, which are often 3-phase and are quite efficient as far as motors and drivers go.

Pulsing brushed dc motor was done before. That's why we have brush-less motors today. They are much more efficient.

off topic post to all :)
Happy new year!
We're aiming the same goal.
The problem is the lack of knowledge and reinventing of the wheel.
Study as much as you can and use your open mind.
We will get freedom someday :)

However, both types of motors are incapable of exceeding 100% efficiency.

Nothing is so far.
What about pulsing brushless motor with high voltage?
Will try that soon.

sorry, i am out of topic.

I think they are a fun project,and can be useful in that they do have the ability to desulphate LAB's-but slowly. Anyone that has built a pulse motor has achieved something,along with learning as they go. But it should have been left at that,but along with it came the faulse claims of self runners and OU machine's-all in the name of making some cash. Most of the ring leaders can be found at EF that peddle there rubbish in the form of books and DVD's, in order to make some cash. This is why i abandoned that forum,while this forum seems to remain on the straight and narrow.

Every DC motor(bar 2 that i know of)use pulses to run.Some are pulsed via mosfet's,transistors,reed switches etc,while others use brushes to pulse each segment of the rotor. The only motors i know that are pure/straight DC are  the bearing motor,and the homopolar motor. but these consume a lot of current,produce a lot of heat,and are very weak as far as mechanical output go's.

as a whole, bedini motor is  chas cambel  flywheel with compact design, ( my opinion).

@HH
everyone  have different piece of knowledge and different view of point, the lack is how to understand  other.

Building pulse motors are loads of fun as can be seen by the recent pulse motor build of competition. They are great for educational purposes and often inspire all sorts of fun designs and applications. As far as ever achieving overunity, well that is about as likely as Rosemary Ainslie getting a noble prize for scientific procedures and ethics. It may never happen, but the lessons learned and knowledge applied my be the building block of another project.


Tinman's reply is far more accurate, I just wanted to add my tens cents worth as requested

I would add an exception, that it depends on the design of the pulse motor (in what manner the pulse is used in the design of the motor), as to whether you can achieve OU or not.  An electrical pulse (that is implemented in a special way) is the only way I have known that OU can be achieved through efficiency gains in a specially designed magnet motor.

How is chas claiming OU if there is none is in his setup?  There are several on YouTube that are powering things that require some real power going to them (drills, saws).  I have done the calculations for kenetic energy stored in the flywheel and it can hold quite a bit.  Also if you consider that if you spin a flywheel that is twice as heavy it only holds twice the energy but if you double the speed of the same wheel it can hold four times the energy.  So how can it not work just because of friction and resistance from the generator side.  With the amount of energy stored in the wheel it would take awhile to slow down that mass even with a large load.  With a small load it would just keep going and if you could apply a large load slowly enough for your motor to recover the speed lost in the wheel cuz of the load, seems to me like it should work.
