Motor Power Comparison

[williamblake69]

i am working on a 1 HP that is powered by 3volts ..... :) ..... almost have prototype complete, i am afraid to make a video of it because i have a patent pending, but we have very similar ideas, :) ..... more TORQUE less voltage to power that torque

I just made a posting on another one of your clips explaining the difficulty in making current measurements with analog or digital multimeters for pulse circuits. You MUST make "True RMS" current measurements assuming a constant voltage source.

This clip shows nothing, and the comparison between the two motors and the wattages are all wildly inaccurate.

In that case, all measurements to DC motors prior to the invention of "True RMS" meters are inaccurate? BTW... all DC motors are "pulse circuits", by definition of "pulse". If I new more about you and your practical background, I may invest the time tot take you quite a bit more seriously.

[Drevtoobe]

I studied electrical engineering about 25 years ago and then worked as a hardware design engineer for about five years in digital design.

You may have read my comments on your other clip. You don't necessarily need a "True RMS" meter to make RMA measurements, you can do it yourself with a scope and some work. The main point is that ordinary multimeters only understand sine waves when it comes to making AC measurements.

[Drevtoobe]

As far as your motor comparison goes, you are comparing apples and oranges. Chances are that the small motor is drawing much less power than your motor, and it may be less efficient as compared to your motor.

A side point for your consideration that you are probably aware of: I saw that you use a standard "pony (sp) brake" for making your mechanical output power measurements. The motor must be turning at a constant velocity when you make those measurements.

[Truthbeeknown]

The small motor was completely stopped when I measured the current and therefore is just a straight circuit with no interrupts or pulses so has to be accurate measurement. No different from measuring current to a light bulb.

[Drevtoobe]

Here is where you made a big mistake. I am not trying to be nasty here, it was truly a big mistake.

You have to measure the current when the small motor is running! It develops back-EMF and therefore the current consumption goes way down. Free-running, the small motor probably dissipates less than 1/2 of a Watt vs. the six-plus Watts that you are claiming.

[Truthbeeknown]

I did and under load as well. Free running it has very little torque. I'm not sure if you noticed or not, but the meters on my motor don't move under load until very very low rpm. Under heavy load both motors "consume" the almost the same amount of current. The big one can't be stopped with two fingers like the little one.

[Truthbeeknown]

Great, but I they never taught you about longitudinal electricity, or longitudinal magneto dialectic waves. With this type of wave one can transmit power to another receiver with a single wire. Not to mention other really neat things.

So how do you count how many watts you motor make? Can you tell me? I have maked Bedini Motor too, and now interested about what it give to me...

[hartiberlin]

What is the point ?

Bigger motors are always more efficient than small mini motors !

Come to overunity dot com to discuss this.

Many thanks.

Point being seven watts should not power a way it does with my motor...
