i found better sticker 

hi again thank for a safety issue problem there with rpm and fingers its simple  and if that not help we need some safety cage around   sorry for confusing with rpm and size of  pulleys that is more technical question for another forum not electrician problem   lets start again   there is...

do you know how much the loss of energy will be on motor , pulley , generator, and others ?  before post I calculate with 100%loss on motor real life is only 80% 50% loss on pulley real life is only 10% 100%loss on generator real life is  90%  

I know how to change bulb if that will help you

read oldest posts I  not a electrical I can't help you with solar panels self ruining thing device  

what you mean  DS?

again it is only theory  is it something wrong calculated there? i don't know how big will be second D of a pulley maybe (size of house)or from what material will be made of (carbon titanium fiber diamond  pulley 1000times stronger than steel )   wind stand torque or power     best motor what i...

we are are off the point here Dj1 if you like CBeebies turn the PC off and watch the TV CBeebies channel and to make Flux capacitor try watch movie back to the future 

From Wikipedia, the free encyclopedia Pulley: 4th century BC An important adaptation of the wheel in technology is the pulley - a wheel round which a rope is run to exert force on an object at the other end. Such a machine is first mentioned in a Greek text of the 4th century BC, but it is...

i did some more research best motor what i found is  SPINDLE MOTOR 1.5KW  24000rpm  (220V~250V Frequency: 400 Hz) and best generator with small rpm is 8kw  120rpm      i don't know if that is important ( 25Hz  3x230V / 3x400V ) 24000rpm /120rpm  = 200 so with pulley  ratio 1:200 we should get...

numbers found off web sites sellers   1- MOTOR efficiency of between 88.5 and 89% go for       80%     20%loss 2- PULLEY  loss of approximately 10%                                          10%loss 3- GENERATOR Typical efficiency values are 93-94%.      90%    10%loss 4- OTHER  heat ...

99% losses on motor that is 1% efficien so how much el energy you need get 1kw of power 1.99kw el e?

yes  do you know how much  losses will be and efficiencies for motor and generator ruff

all energy will be transformed to electricity is it?

or what you think is real life efficiencies for motor and generator

from internet Electrical motors constructed according NEMA Design B must meet the efficiencies below: Power (hp) Minimum Nominal Efficiency1) 1 - 4 78.8 5 - 9 84.0 10 - 19 85.5 20 - 49 88.5 50 - 99 90.2 100 - 124 91.7...

Motors are about 90% efficient at converting electricity to mechanical work. Generators are also abpout 90% efficient. to get 1kw power of motor then need 1.10kw el energy  to get 1kw of el energy need 1.10kw of power I'm not electrician is it ok?

electric motor powering generator then generator powering motor back 

1 kw spare should be electric energy 

Hi      WILL IT WORKS? 1KW el mot 4000rpm powering true pulley 1:4 generator req. (1000rpm and 4kw power) to make 3KW el energy generator will power the motor back  yes i know there are some loss  so let say we need 2kw el. energy get 1kw power of el. motor  and we need 4kw power to get 3kw...
