Wireless Electricity (Tesla coil method) works at very high voltages and frequencies...... induction motors cannot run normally at such high frequencies (forget high voltages).hi all can any body have an idea about wirless electricity i have an idea i can explain for midrange electricity can anybody guid for large induction motor thanks in advance
you can go in for high frequency inverters like the ones used in emergency lighting or energy saver CFLs....... it will be much lighter on the walet to buy the same from a 2nd hand market!@way2afroz
u said you know how to work it at midrange electricity. cud u plz elaborate on your setup and its dimensions also how did u obtain the higher frequency (of the order of 10Mhz). i plan to work on witricity as my project and with my virtually background im stuck on the part of obtaining 10Mhz signal which can give sufficient current to light a 60w bulb.im trying to achieve this by using colpitts oscillator.
Thats the reason i suggested u go in for ready made ckts from 2nd hand markets.i tried making it but due to excessive current my inductors got burnt
i need a frequency of around 10 MHz...u think i might get from these high frequency inverters? do energy saver CFLs hav these circuit in them,coz then ill get a CFL and break it down to that circuit.
Greetings,Tesla Coils are very Dangerous! You should NOT build or operate one without being aware of the risks.
Electrocution
Mains voltages, 110V or 240V can kill you! Everyday household appliances are built with protection, fuses and earth wires. The control systems for your coil must also be designed and built with fuses and earthing - all exposed metal MUST be earthed and a correctly rated fuse MUST be fitted.High Voltages present in the NST, tank capacitor, spark gap and primary coil can kill you! Never touch these components when mains power is ON! Even after power is disconnected do NOT touch until you are sure the tank capacitor is fully discharged.Streamer Strikes!
Direct strikes from a running coil can kill! Watch out for secondary strikes too - a strike to a metal structure will flow internally and may exit the structure at a point near you!Fire
Be aware of the possibility of Fire. Never run a coil near flamable substances. The output streamers can travel through wood and heat it up to the point of ignition.
Health Risk
Electrical discharges in air cause chemical reactions which produce toxic gasses such as ozone and oxides of carbon and nitrogen. Prolonged exposure to these gasses can cause irritation to the lining of the lungs and to eyes. Never operate your coil in a confined space without suitable ventilation.
Spark gaps produce a lot UV radiation. Never stare at a running gap.
Pacemakers can be affected by the Electromagnetic Fieldgenerated around a Tesla Coil. Follow your manufacturer's advice and keep clear.
Noise
Tesla Coils are Very Loud! Wear suitable ear protection.
Accidents
Play safe! Don't operate your coil in cramped conditions. Give yourself and spectators plenty or room. Don't leave cables where you could trip over them.
Caution
Tesla Coils generate an Electromagnetic Field which can induce electrical currents to flow in nearby conductors. Do NOT run your coil in the vicinity of electronic equipment (e.g. computers, camcorders, house wiring etc).
Spark gaps and streamer strikes can cause EMI (ElectroMagnetic Interference) on TV and radio broadcasts. Think about your neighbours - they may complain if their favorite TV show is interfered with!
EMI can flow back through your transformer and control circuits and into the domestic supply. Electrical equipment can be damaged this way so use a mains filter.
