You think the people that lost those planes don't care? and find it funny?

Ok...

Have a good day.

If a different wind or fault tolerant redundant setup like dual inverters were employed and saved them what is the joke bruder? Is there a remote answer for his friends with the smoking carbon fiber and burnt fingers there? There are many more incidents than these captured in HD! Is it a laughing matter above 50 volts???

Mr. Mark Duvall, Esq., Principal
Beveridge & Diamond
1350 I St, N.W., Suite 700
Washington, DC 20005

Dear Mr. Duvall:

Thank you for your January 23, 2015 correspondence to the Occupational Safety and Health Administration (OSHA), Directorate of Enforcement Programs. You requested clarification of OSHA's electrical guarding standard at 29 CFR 1910.303(g)(2)(i).

Question 1: Does the electrical guarding requirement at 29 CFR 1910.303(g)(2)(i) apply to voltages below 60 volts DC?

Response: The provision in question, 29 CFR 1910.303(g)(2)(i), generally requires "live parts of electric equipment operating at 50 volts or more" to be "guarded against accidental contact by use of approved cabinets or other forms of approved enclosures" or by other specified means. The guarding requirement does not distinguish between AC and DC voltages. Therefore, the requirement applies to live parts operating at 50 volts or more AC or DC.¹

Question 2: If 29 CFR 1910.303(g)(2)(i) applies to live parts operating at 50 volts or more AC or DC, will OSHA treat a failure to guard live parts operating below 60 volts DC as a de minimis violation?

Response: No. A de minimis violation occurs when an employer deviates from the requirements of a standard in a way that has no direct or immediate relationship to employee safety or health and in other limited circumstances in which the employer's non-compliant actions provide employee protection equivalent to or greater than that afforded by the applicable standard. See Field Operations Manual, Ch. 4, Sec. VIII (CPL 02-00-150, April 22, 2011). OSHA does not believe that the scenario described in your question satisfies these criteria. Failing to guard live parts operating at any voltage over 50 volts, DC, is not as protective as, or more protective than, guarding those parts, and does have a direct relationship to employee safety. Therefore, a lack of required guarding in your scenario would not be a de minimis violation.

You point out in your letter that some consensus standards consider live parts operating between 50 and 60 volts, DC, to be non-hazardous under certain circumstances. However, OSHA considers all voltages of 50 volts or above to be hazardous. Electric current, not voltage, passing through the human body causes injury, and the amount of current passing through an object depends on the resistance of the object. As explained in Appendix C to 29 CFR 1910.269, theinternal resistance of the human body is 500 ohms, which is the minimum resistance of a worker with broken skin at the point of contact. The current through 500 ohms from a live part energized at 60 volts would be 120 milliamperes. This level of current, either ac or dc, is sufficient to cause serious injury.²

We are aware of documented cases where serious injuries occurred when employees contacted live parts operating between 50 and 100 volts, DC. See, for example, https://www.osha.gov/pls/imis/accidentsearch.accident_detail?id=775742&id=142950 83.³ In fact, although OSHA's standards require guarding starting at 50 volts (AC or DC), it is not necessarily the case that voltages below that level are completely safe, We have heard of cases in which auto mechanics have sustained serious injuries working with 12-volt or 24-volt (DC) vehicle batteries. (See, for example, http://www.ncbi.nlm.nih.gov/pubmed/23937760; http://www.researchgate.net/publication/7737406; and http://www.medbc.com/annals/review/v.../vol5n1p33.htm.)

Thank you for your interest in occupational safety and health. We hope you find this information helpful. OSHA requirements are set by statute, standards, and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at http://www.osha.gov. If you have any further questions, please feel free to contact the Directorate of Enforcement Programs at (202) 693-2100.

Sincerely,



Thomas Galassi, Director
Directorate of Enforcement Programs

You're at 60 volts and 300 amperes. Is it a joke? So you see this is the ignorance I am talking about. Maybe the Dr can save you in the field as well.

Remotely.

For him e-traction power system failures at these power levels is a game. He suggest simultaneously after telling you he is not responsible for your impending fire that your smart inverters that are lighter with twice the power density don't perform well enough for speed planes and what you should use an inverter with no fail safes and 25 year old fets so that you can run it into power levels where it will certainly fail at since they are unregulated now and can widely exceed disclaimed power levels of the motor and inverter and batteries. You also need to remove the temperature sensor so it wont limit itself and save you either.

WTF!



You all have a nice day, and enjoy his ignorant editorial over there in Germany. Have fun with those 5050s just like he said.

For the new year I'm going to prepare easily for the intelligent people in Germany and the American pilots here something else First.

My new cut is not really necessary to out perform a parallel wye wound powercroco 5050 scorpion. We have an entirely different winding and motor tuning program. He is just anxious to see my new stators.

[Clugh]

5040 360KvThey also manufacture 4225 Kits so preparing something to compete with the HK crocoturds shouldn't be too difficult for the pilots not exclusively subscribed to the GSM. Its the same as a scorpion. Manufactured in China... I haven't seen the motor physically yet to measure it and determine if it has as much iron under the coil as a pyro 1000 but a scorpion certainly does not from the onset of any motor wars....


Hubert

[Clugh]

For 180.00 kit plus a winding with much better building materials...This is an easy way to free yourself from the nonsense in Dresden.

[Clugh]

Have you seen Lee Bell's machine work????

[Clugh]

[Clugh]

Excellent.

[Clugh]

[Clugh]

Excellent OEM winding. 👀

Ralphs 375 kV 5050 erzeugt etwa 2,48 N/cm pro Ampere, also kann er bei 300 Ampere für 5 Sekunden 7,44 Nm bei 22.500 erzeugen, das sind 17,5 kW. Das Problem ist, dass er den Propeller nur mit etwa 16.000 U/min dreht, also erzeugt er mechanisch tatsächlich nur etwa 12,46 kW. Wenn er also 17,5 kW oder mehr Eingangsleistung dafür verwendet, beträgt der Wirkungsgrad etwa 71 % oder weniger, ebenso wie die Drehzahlsteifigkeit. Die eigentliche Arbeit hat über 400 Ampere erfordert, also hat er 24.6 kW als Leistung angegeben.

[Clugh]

"My old 5040 motor has seen the 400A with my 2017th YGE 400 prototype, so the 5050 cannot have been saturated with the same amps - it has 20% more iron and magnets too."
~Ralph Okon~

That statement alone let me know he's clueless about what happens. More magnet can saturate more iron....

they grew together...dingleberry




Later boys.....

[Clugh]

I see your reporter told you to hurry up and get over here

Today, 12:55 PM

what's the German social media on what's app have to say about it?

u see at 400 amperes consumption it only generate 14,500 rpm at the prop. U have more of a problem with your numbers than I have even predicted bro....

The motor has a tremendous amount of difficulty pulling the necessary prop to exceed 600 km/h with any level or normalcy. Like you reported the wind, thin air, and good pilot maneuvers might push it along to that once in awhile with ALOT of risk involved.

Were getting closer to the truth now Ralph. Keep pushing. I know it is hard work!


Hubert

[Clugh]

What he does is play with you guys intelligence as he sits right here on this board but replies remotely on the German forum like somebody crazy.

I'm trying to tell y'all he is silly. See the 14,500 rpm @ 410 amperes draw....so with his new disclaimer you are clearly no longer guaranteed these speeds. 300 amperes which its only rated for 5 seconds now will not get you there.


Hubert

[Clugh]

Ill never play the boys cheap. And I'll never knowingly lie to them about a motor

Thank you,
Hubert

[Clugh]

Oh no Ralph you're wrong and remote speculation in Germany will not get you a photo here. If I want this cut it would be used already. Team xerox is more your thing. You never got your copies correct either. I wonder why u post 3 regular 5050 stators beside it.... they're only good for 12kW continuous operation. 😁

I could wrap and show the goof troop the waveform today in 10 minutes since they cannot do it for themselves. Your version of any stators in question was cut wrong and wound wrong. Since I have a paper direct from Hanz I already know what the waveform looks like from the parallel slot geometry. Where is your dog shelter version of it put it on your scope if you know how to use it. Wrong person wrong motor as there is zero intention to use a parallel slot stator cut. I do not need anything like to deal with the marginal performance you have produced. Just a different wind will do that. You just don't understand how any of it works and never have. They are asking you questions about what goes on here huh? No you just answer remote because you have issues. The only one puzzled is you.😄 Looks like you lied again and are actually posting more after the end of November. What happened to the power ditto eulogy?

It will be back open in a few weeks when you miss the little attention it gets too much .

[Clugh]

Sie posten nur irrelevante Dinge, um von all den Lügen abzulenken, die Sie erzählen. Sie sind wirklich erbärmlich und verschwenden viel Energie mit sozialen Medien. Wie wäre es, wenn Sie eine Maschine bauen würden, die effizienter ist als die 80er-Marke.

Hier drin um 7 Uhr EST auf der Suche nach einem Knochen. Einer wird nicht veröffentlicht. Lassen Sie einfach Ihre George Foreman Grills laufen

Thanx
Hubert

[Clugh]

Bitte beachten Sie, dass 410 Ampere multipliziert mit 60 Volt einen Verbrauch von 24,6 kW ergibt, aber 7,44 Nm bei 14.500 U/min nur 11,3 kW mechanische Leistung sind. Die sollten sich nicht um den Actro scheren und sich um den Mist kümmern, den Sie ihnen verkaufen. Das Thema dort sind die Klopfer.

Ralph spielt wieder mit seiner Weihnachtsdekoration

Translated

Please note that 410 amps multiplied by 60 volts gives a consumption of 24.6 kW, but 7.44 Nm at 14,500 rpm is only 11.3 kW of mechanical power. They should not care about the Actro and should worry about the Powercroco motor you are selling them. The thread there is titled the scorpion knockers by Powercroco not cuts by Clugh

You are pulling out Christmas decorations again

Look at your numbers

It doesn't make any torque really! Speed stiff? More like bubblegum. Look at the graph goof troop 👀 to pull a few more rpm at the top the amperage rockets but the torque to provide more rpm does not. That's your desynchronization buddy no more pullout torque. Keep trying and the motor and "dummed" inverter die. Like your 320 and 400 did....😶

Simple.

Have a good day Ralph....
