Yes, of course there is.Electromagnetic radiation from have any wires through which an electric current flows.In any such motor wires - many hundreds or even thousands of meters.Electromagnetic radiation - this is what is based on the principle of the motor.Not quite true.electromagnetic radiation of the engine - a low-frequency electric.magnet.wave frequency 50Hz( for driving. AC).But the principle of e-mail.Engine - rotating frame with a current in a magnetic field, which may be permanent - more than a year ago
Radiation from any electrical appliances there.Any conductor through which flows an alternating current emits radio waves into space.Radio waves - not that other, as electromagnetic radiation.
Another question - what is the power of this radiation?We can confidently say that the power of the induction motor of the radiation, which are used in elevators, very small.Firstly, the radiation itself has no more power.Secondly, the motor housing is grounded and shields the radiation.
Unlike the asynchronous motor, collector creates quite a powerful electromagnetic radiation over a very wide frequency spectrum.Sometimes it is even a hindrance to listen to radio, watch TV.Yes, once I had a neighbor who works in a drill.Television at neighbors with rippled. - More than a year ago
