When a dynamo-electric machine is caused to produce an electric current by the intervention of a steam-engine, the transformation of energy which takes place from the energy of the coal to electric energy is an extremely wasteful one.
Such an electric source was given to the world by Faraday through his invention of the dynamo-electric machine, and it was not until this machine was sufficiently developed and improved that commercial electric lighting became possible.
Magneto-electric machine, a form of dynamo-electric machine in which the field is maintained by permanent steel magnets instead of electro-magnets.
The name dynamo-electric machine is given to it, because the electric current is not induced by a permanent magnet, but is accumulated by the mutual action of electro-magnets and a revolving wire cylinder or armature.
It is found that, as the dynamic force required to drive the machine increases, so also does the electric current; it is therefore called a dynamo-electric machine.
The latest improvement has been that from the magneto-electric to the dynamo-electric machine.
The magneto-electric machine imagined in the former paper gave a means of estimating the electromotive force of a cell or battery in absolute units.
A magneto-electric machine and an alternating current generator are the means for generating this form of current.
A leather bag A at one side of the wooden case (figure 99) holds a double conductor leading wire, which is used for connecting the magneto-electric machine to the bridge.
This is the fundamental principle of the well known dynamo-electric machine, popularly called a dynamo.
The apparatus consists of a magneto-electric machine AT, which generates the testing current by turning a handle, and a Wheatstone bridge.
The magneto-electric machine, as it was called, remained virtually in this form for many years.
The influence of the magneto-electric machine, therefore was not direct, but indirect.
The magneto-electric machine of the Alliance Company soon succeeded to that of Holmes, being in various ways a very marked improvement on the latter.
Many inventors tried to obtain it cheaply; and in 1853 an attempt was made to organise a company in Paris for the purpose of procuring, through the decomposition of water by a powerful magneto-electric machine constructed by M.
By turning the handle of a magneto-electric machine a coil of wire may be caused to rotate between the poles of a magnet.
Pacinotti states that it occurred to him that the value of the apparatus would be greatly increased if it could be altered from an electro-magnetic to a magneto-electric machine, so as to produce a continuous current.
On putting an electric machine in communication with such or such a one of these wires, the ball of the corresponding electrometer was repelled, and the motion signaled the letter that it was desired to transmit.
The two electrometers were connected together by means of a conductor (C) passing under the earth, and which at either of its extremities could be put in communication with either anelectric machine or the ground.
I am at home," says Reusser, "before my electric machine, and I am dictating to some one on the other side of the street a complete letter that he is writing himself.
On the contrary, they were constantly wrestling with the problem, in some instances being fairly successful, even before the invention of the magneto-electric machine.
In so doing he constructed the first dynamo-electric machine.
When the water is heated in the hydro-electric machine or other boiler, to 322.
It consists of a very powerful magneto-electric machine turned by a steam-engine, and connected with the large troughs containing the silvering solution.
With the assistance of the magneto-electric machine, telegraphic communication may be conducted without the assistance of a battery.
With a magneto-electric machine he employed mechanical power to produce a current, and the energy of the current he converted into heat.
Wilde employed a magneto-electric machine to generate a current which was used to excite the electro-magnet of a similar but larger machine, having an electro-magnet instead of a permanent steel magnet.
A footnote in a current encyclopedia states that: "An account of the Magneto-electric machine of M.
Pacinotti, of Florence, constructed a magneto-electric machine in which the current flows always in one direction without a commutator.
Its lineal ancestor was the magneto-electric machine, in the early construction of which figure the names of Siemens, Wilde, Ladd, and earlier and later electricians.
As soon as the magneto-electric machine attained a size in the hands of experimenters that took it out of the field of scientific toys it began to be what we now know as a dynamo.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "electric machine" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
