The inductors have distinctive coverings for the different phases.
Then the current in the inductorson either side of and adjacent to it will be in the same direction.
In this type the positive polar projections of the inductors are set opposite the negative polar projections as shown in fig.
These disturbing fluxes form, in part, stray fluxes linked around the armature inductors tending to choke the armature current.
The coils composed of several turns of wire or copper strip are wound in place, and after covering with a layer of insulation, the outer wedge is pushed in place to retain the inductors in position.
Inductors consisting of iron discs are arranged on a shaft to rotate through the air gap of the magnet poles.
The armature inductors are of the closed coil or delta connected type, but are tapped at three points per pair or poles to the three collector rings.
This name is given to a type of winding possible with open or only partially closed slots, in which coils previously formed are introduced, only a few inductors at a time if necessary.
The pressures induced in the inner windings of such a coil are opposing each other at the instant depicted, that is, while the inductors are under the pole face, such action of course being objectionable.
The complete winding for the three phases are here visible, the field magnets being represented as transparent so that all of the inductors may be seen.
Inductors A, and B are lettered to correspond with fig.
There must be either numerous inductors per slot or numerous slots per pole.
Now if a number of these inductors be connected up to form a distributed coil as in fig.
But a flash or two from one of their inductors will destroy this house just as surely as it did my brother's cottage.
This is a form of drum winding in which the inductors are arranged in two layers and carried out obliquely on an extension of the cylindrical surface of the drum to meet and connect with radial risers.
The inductors of a disc armature move in a plane, perpendicular to the direction of the lines of force, about an axis parallel to them as shown in fig.
This condition =must= obtain in order that the electric pressures induced in inductors moving simultaneously under poles of opposite sign, will be added.
The average pitch should be approximately equal to the number of inductors divided by the number of poles.
In this type of winding, the end connectors project from the inductors in straight lines parallel to the shaft and then are bent inward.
In these windings, the division of what otherwise would be very stout inductors into several smaller ones, has the effect of reducing eddy current loss.
Two or more layers of strong paper, fibre, canvas or mica, should be applied to the core before placing the inductors in position.
It involves an increased number of inductors and commutator segments, which is undesirable in small machines, but for large ones might be allowable.
With slotted armatures what provision must be made for retaining the inductors in position?
The inductors of an armature may be placed on a smooth drum or in slots cut in the surface parallel to the axis.
Magnetic leakage through the core may be reduced by making the amount of metal above the inductors very small.
It should be noted that, although screened from the field, the inductors in a slotted armature cut magnetic lines precisely as if they were not protected.
The width of "fringe" of the magnetic field is influenced by the shape of the pole piece; the margin of fringe should be such that the flux density will vary from zero to a high value where the inductors enter.
Various shapes of pole piece for securing a gradual entrance of the armature inductors into the magnetic field.
How are the inductors connected to the commutator?
To provide a field of magnetic lines or lines of force to be cut by the armature inductors as they revolve in the field.
It differs from Varley's and mine by leaving the inductors to themselves, and using the current in the connecting arc.
Paper inductors are fixed upon the back of it, while opposite the inductors, and in front of the revolving plate, are combs.
To keep all the paper inductors on one side of the machine to a like excitement, I connected them together by a metal wire.
These rings are punched to receive the inductors in such a manner that there is an unbroken strip of metal completely surrounding them.
Moreover, the short circuiting rings are set some distance from the end of the core, so that the inductors between the core and ring act as vanes to force air through the coils for ventilation.
Copper bars are used as inductors in the larger sizes, and copper rods in the smaller sizes.
In starting the inductors are short circuited through a resistance which is gradually cut out as the motor comes up to speed.
The inductors consist of solid copper bars embedded in the slots of a laminated core, with their projecting ends securely fitted and soldered to heavy copper rings.
Good electrical contact is obtained by expanding the inductors in the end ring holes.
The inductors are welded to the short circuiting end rings, the latter being located beneath the inductors, as shown.
The features of construction as seen in the illustration are bar inductors, ventilating passages through the core laminæ, riveted connection between inductors and end rings ventilating vanes on end plate, extra large end rings.
The ends of the inductors are turned down somewhat smaller than the body and fit in holes in the end rings.
These inductors are set edge on, and are riveted and soldered into resistance rings.
Motors having this feature are commercially known as ~slip ring motors~, because connections are made between the external resistances and the armature inductors by means of slip rings.
The armature inductors or copper bars laid in the core slots are short circuited by these end rings, which are also made of copper.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "inductors" in a variety of sentences. We hope that you will now be able to make sentences using this word.
