For a very long time in history, heavy duty work were carried out manually by men making such task burdensomeand heavily tasking.In the year 1821, relevant discoveries were made simplifying the effort and time while performing such task. The conversion from one form of energy to another form of energy particularly from electrical energy to mechanical energy through the electromagnetic means or processes was first revealed by arenowned British scientist Michael Faraday in the year 1821 after performing series of experiments. By 1882 Nikola Tesla had discovered the right use of rotating magnetic field to operate machines and heavy duty devices.
Having the essential advantages of reliable procedure, low cost, straightforward layout, easily discovered replacements and having a variety of mounting styles and procedure,AC motors(Wechselstrommotoren) are now very popular and are extensively used. They have been designed such that it has a chain of windings in a rotating section interior and the outside. The transforming electrical field due to the AC line voltage will get the rotor turn Here the speed of the motor will be contingent on the torque load on the motor, frequency of the AC line voltage and the fixed variety of the windings. A wide use of these AC electrical motors hasmade the search for replacements and spares a simple task.
These motors which seem indispensable also have a few disadvantages like having an expensive speed control, its inability however to function at low rates and the poor placement control. The electronics required for an AC motor are higher priced as compared with DC Motors (Gleichstrommotoren). But for programs which are bigger than 10 Horse power (Hp) these AC motors are usually more cost effective when compared to the DC Motors. The AC motors are the most preferred of all motors for the fixed speed applications in the commercial and domestic uses. They have been foundto have broad applications in stationary power tools like air conditioners, washers, dryers, fans, blowers and vacuum cleaners.
AC Motors (Induktionsmotoren)are available from suppliers such as Powertronic, Shayang Ye, TransmotecandDunkermotoren.
