Notes on Kromrey Converter US Patent 3,374,376

The construction of Kromrey converter by Raymond Kromrey. US Patent 3,374,376 Mar 19, 1968:

• The shaft has to be NON-MAGNETIC! Must be aluminium, brass. stainless steel. 
• 4 independent coils.
• The middle ones are brushes. 

How it works:
The coils are locked by the magnetic fields. When you turn them, you break the magnetic fields and they discharged.

If the shaft is magnetic, the magnetic flux will look like this. This is the wrong magnetic flux that we don't want.

The right magnetic flux is this.

The flux direction

The coil polarity is indicated as below.

The bloch walls:

They are at the magnets between the north poles and south poles and also between the coils at the centre of the shaft.

The energy comes in at the bloch walls. Sucking in energy and expelling energy through the coils.

Unique feature:
Under load, it accelerates. The current goes down instead of going upward.
It is 120% efficiency. But, to get to be a free energy device, it has to be 300% or more. This is told by scientist who worked for government laboratory.

Maximum efficiency is 180% with this machine. It can  be used to charge battery. It can get up to 350% if the coils are parallel with low impedance.

G-field stresses the gravity field.
The coils are hot but the surrounding is cold. Battery is very cold. Bulb is hot at ONLY one spot where the finger is touching. Energy out is cold electricity. It speeds up when charging battery. Fly wheel is used to quite the machine and smoothen the magnetic lock.


The magnets are the stator and coils are the rotor. Comparing to DC brushless fan, the magnets are the rotor and the coils are the stator. Meaning the DC fan should be rotated by another motor and make the fan a generator.
