Hi.

Let me help you with some misconceptions.
It's not an Electro Magnet Motor, it's called a Magnetic Wankel Motor.
In my case the proper technical name would be Dual Induction Split Spiral Motor.
You should know that building one of these motors take a lot of money, and then you need
to be very skilled in both mechanics and electronics. There is no shortcut in these matters.
If you want a lot of power output, enough for the average villa, you need to build it really big.
Once I'm ready I will tell about my findings. Until then you will have to wait. Stay tuned.

Hi Honk

Thumbs Up!

helmut

Keep up the good work Honk.  While many of us arm-chair mechanics would love to post and offer help, my 2 degrees in Mathematics shows myself quite clearly to sit back and watch all the cool work of those on this forum. heck this might be my first post.....you seemed fluster a few pages back.  Just wanted to show support.


 

Keep on rolling!!!

what happend if think in 3D, adding Z axis to the ramp system?
think in that please, left the 2D systems

Install and use this program.

This reminds me very much of the Adams Pulse Motor. There the stator was made of a steel rod. The magnets on the rotor were attracted by those rods. When they reached a parallel position, the copper coils that were wrapped around the steel rods were pulsed for a milisecond by a reed contact, resulting in repelling the magnets, passing by the sticky spots.
The E-Magnet was powered by a 1.5 V recharchable battery (at least in one test run). I think the BEMF then refilled the battery frequrently. Nonetheless it used to run only for a couple of hours.

I even found some pics of the mentioned experiment: http://www.melog.ch/adams/

Out of curiosity, why is it required in the design to  use a pulley driven generator, why not design your own generator to operate off the same shaft?  Are you using a ration with the pulleys?  They cost you a lot of friction.  If you do use pulleys, I suggest a timing pulley with timing belt instead of v belt.  The timing belt can operate with less tension(belt friction).

I suggest that you incorporate a round plate attached to the shaft in the same diameter of the inner section diameter of the 2  rows magnets.  On the plate mount one tiny magnet, then mount 8 hall sensors onto a fixed plate at 45 degrees exactly, whereas the rotating plate causes the tiny magnet to pass by the hall sensors.

The hall sensor outputs a pulse to a microprocessor which then calculates and displays on TV or LCD the average speed, acceleration, any sticky points along the 8 separate measurements it takes.  The processor controls precision timing of the pulses to the electromagnets, with compensation for acceleration and decel. 

With the processor, any control needed for PWM, pulse duration,  phase control of electromagnets, etc is managed easily.

I use the processor called the Propeller by Parallax.  80mhz, 32 i/o, with 8 processors on board, more than enough power and speed to manage the motor with minimal power consumption. An optical encoder on a shaft could make for more even more tighter precision of timing.

If I were developing a motor from scratch,  microprocessor controls and monitoring of feedback would be of utmost importance.

I have also considered whether the 2 magnet rows should not be capable of swivel, if not even motorized swivel for fine tuning and testing.

You cannot refill anything from BEMF because there is always hysteresis, eddy currents and copper loss within a coil.
Every bit of loss is responsible for getting less power back than is put in. Thus no OU by returning BEMF.
I guess the Adams Pulse Motor just run for as long as it took for the battery to get drained.

Adams motors have achieved COP=8, but much depends on understanding that the pulse in the coil
is not to attract or repel, but merely to cancel out the effect of the rod once it has done its work
by attracting the magnet. The current in the coil makes the rod go away, if you follow me. The capture of
BEMF with capacitors and returning, often to a battery is important top teh COP outcome.
