Magnetic energy pump OU motor

btw. (what you describe is not Lenz - but none the less)

Sorry, I thought I knew about Lenz's law that causes the generator drag when loaded.
Perhaps I'm wrong here but maybe we mean the same thing but use different terms.

Quote from Wikipedia: http://en.wikipedia.org/wiki/Lenz's_law
----------------------------------------------------------------------------------------------------------------------------------
A demonstration that illustrates Lenz's law is:

Find a small electric motor.
Spin its shaft.
Connect its wires together (with a paper clip or alligator clip), and spin the shaft again.
This time, the motor resists turning, because current can flow through its wires.
----------------------------------------------------------------------------------------------------------------------------------
If I'm wrong about this, then how do you describe Lenz's law in easy terms?

I didn't know that at half RPMs the power product is highest and this will help a lot - unless magnets will change power output peak appears at some other RPM value.

It doesn't matter how you design the motor. The half RPM output is caused by the motors own losses.
At increased RPM more and more torque is lost within the motor due to windage and bearing losses.
It's actually self-explanatory.

Letting the motor spinn freely without any load all torque is used up by the motor itself to reach maximum peak speed, aka Free RPM.
Braking the motor to stand still will give you all available torque without any spinning losses, aka Stall Torque.
Just in between these extremes you find the sweet spot where you get Half the Rpm at Half the Torque, no matter how you design the motor.

If you somehow can increase the torque you will automatically increase the free rpm by itself, which must be loaded down to Half Rpm at Half Torque.
And there you go again. Getting your maximum at the same way as before. Half the Rpm at Half the Torque but a higher output as both Rpm and Torque has increased.

Here's a link that describes it: http://www.gizmology.net/motors.htm

Hi all !

I done some research to determine closest simmilar motor name ...

the closest match is

Switched Reluctance Motor Drives

http://www.fleadh.co.uk/srm.htm: http://www.fleadh.co.uk

but must be noted that rotor is laminated so no induction of current (and has no coil of any kind on rotor) appears in rotor therefore no Lentz.

see allso Lindemann motor allso Lentzless

...so after establishing that this is magnetic reluctance motor type... dating from 19th century (but unable to be driven efficiently, no mosfets - at that time, so design was abbandoned till recent years)

their properties are (unlike induction):
- lentzless motor
- no back force (or any back effects) from applied load
- since efficiency of these types of motors is very high (higher then induction mot.) they again, in last 10 years, arrise in production quantity.

further (only in OU and FE development - not yet in industry !?!):
- by adding permeable magnets and established and prooven Magnetic Transistor (using change in reluctance) theory/practice
efficiency of these motors must exceed at least 100%......(many finished experimental - Hildebrand, Flynn .... motors confirms it is so and even reaching 200% - 300%)

this is where this thread will continue from:

this experiment allso solved some questions:
nonoriented silicon iron is good material for this motor - no residual magnetism after coil is switched off (but using frq 1khz and lower is must - for now lower freq. the better)
(but even if there is residual mag. - specially build stator sequence with changed polariti of mag. transistor can reuse this magnetism....)

...due to luck of small money surplus...further development of actuall motor is on hold for some time....
