Coils F F are wound from one part K to the one next adjacent, the ends or loops of each coil or group of wires being carried over toward the shaft, so as to form U-shaped groups of convolutions at each end of the armature.
Armatures are wound with a number of turns of wire in each coil, unless the machine is very large, and present an appearance more like Fig.
The ring A is the armature core, and is made of iron; the wire coils are represented as consisting of one turn to each coil, and are marked w w w.
Each coil unit is here divided into two concentric coils of different dimensions and connected in series, as shown in detail in fig.
Each coil is completely insulated before being placed on the core and no insulation is placed in the slot itself.
Each coil is then dipped in an insulating compound and afterwards baked to render it impervious to moisture.
Here the path of each coil is easily distinguished by means of the varied insulations although in part hidden by the drum.
Opposite these are letters and figures designating the path and connections of each coil.
By using strings of different colors to represent the various coils, the path of each coil is easily traced when the winding is completed, as in fig.
If this armature be rotated through the magnetic field as shown, a reversal of current takes place in each coil, when it is in such a position that one of its diameters coincides with the pole line, NS.
Each coil is protected by an insulating sheath and tape covering before mounting.
The other terminal of each coilis connected to an individual block, there being one block for each coil.
By measuring the resistance of each coil with an ohmmeter or Wheatstone bridge.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "each coil" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
