Adams Pulsed Magnetic Motor (page 2)
Adams Motor Update (22 Sep 2002)
This next set of experiments was preformed using the adams motor with
generator coils to see if the efficiency can be improved over just using
Back EMF.
Only electrical input and output power were measured
(no mechanical friction losses included). The motor was operated at
about 1290 RPM's. Measurement were taken using two different types of
coils.
Above is a circuit diagram of coils wound exactly the same as the drive
coils. The four generator coils are wired in series.
Here is a single generator coil, driving a full wave bridge rectifier.
This coil is a high impedance coil using very fine wire, Much finer than
the drive coils.
Above is a summary of the results using the generator coils compared to no
coils. the case (e) "inf." is the case where no generator coils are
used. (Of course, infinite resistance would effectively be the same as
no coils used since it would be an open circuit.) Case (d) is using the
four (identical to drive coils) generator coils. Notice as the impedance
goes down, so does the efficiency at low values. Remember lower impedance
means more current is flowing through the generator coils. This seems to
imply that more current produces more drag on the rotor. Now Notice that
case (a) has a higher efficiency than case (d) at a load impedance of 100
ohms. Case (a) uses a single higher inductance coil wound with very
fine wire (with only a single diode rectifier). Also the coils are
positioned toward the back of the core,
(away from the generator magnets) while the core extends close to the
coils. I built the coils this way based on information in a free
energy video that Muller provided. Again this high impedance coil (with
the windings placed at a distance) had a higher efficiency than the lower
impedance (inductance) coils (which had some of their winding close to
the rotating magnets). Case (b) used the high impedance coils, but moved
close to the magnets. Case (c) again uses a single coil (high
inductance) with the windings
move to the back again, but using a full wave bridge rectifier instead.
In conclusion is does appear that in some cases [(a) and (c)] a higher
efficiency was
measure using the generator coils than without (e).
