\VINOESLAS OAMILLE REOHNIEWSKI, OF PARIS, FRANCE.
in CORE FOR DYNAMO-ELECTRIC MACHINES.
SPECIFICATION forming part of Letters Patent No. 378,375, dated February 21, 1888.
Application filed December 8, 1887. Serial No. 257,347. (No model.) Patented in France January 3, 1887, No. 180.659.
To all whom it may concern:
Be it known that I, WINCESLAS CAMILLE RnoHNIEwsKI, a citizen of Russia, residing at Paris, in the Department of the Seine, France, have invented a new and useful Improvement in Dynamo Electric Machines, (for which I have obtained French Patent No. 180,659, dated January 3, 1887,) of which the following is a specification.
'Ihisinvention relates to dynamo-electric machines; and it consists in an improved method of constructing and combining the cores of the electro-magnets and armatures, as hereinafter explained.
It is well known that in the construction of dynamo-electric machines it is very advantageous to employ electro-magnets having a core of soft iron, and especially of soft iron that has been worked-that is to say, rolled or drawn out to a considerable extent.
According to this invention the elements or plates of the inducing electromagnets are or may be stamped or out out from the same sheets as are employed to make the core of the armature or induced part composed of sheetiron disks or rings, and in constructing the machine these elements or plates of the electro-rnagnets are arranged side by side in the same way as the disks or rings forming the core of the induced part. By these means electro-magnets are obtained presenting a very superior structure. Moreover, the plates or laminae composing the cores can be insulated from one another in the same way as the disks or rings of the armature or induced part, and the improved electro-magnets can be combined with toothed armatures, or armatures having parts projecting radially (outward or inward) at their periphery.
The advantages attending toothed armatures-that is to say, a powerful inducing or magnetic field with a small expenditure of electric energy in the field-magnetscan thus be obtained without producing in the polepieces the Foucault currents, which usually result from the passage of the teeth of the armature before the said pole-pieces.
In order that the said invention may be fully understood, I shall now proceed more particularly to describe the same, and for that purpose shall refer to the several figures on the annexed sheet of drawings, the same letters of reference indicating corresponding parts in all the figures. These drawings illustrate, by way of example, the application of the improved system of construction to various types of dynamo-electric machines, Figures 1 to 5 being elevations of different types of machines, and Fig. 6 a cross-section on line 6 6. of the type shown in Fig. 2.
In each of the figures, A represents the fieldmagnets, composed of a number of plates stamped out from sheets of wrought-iron; a, the exciting coils, and B the armature.
Fig. l of the accompanying drawings represents an elevation, partly in section, of a horseshoe-magnet combined with a Siemens drum armature provided with radiating teeth. On referring to the drawings it will be seen that plates or laminae forming one element or plate for the armature and one for the electro-magnet can be cut from one rectangular sheet of iron. The electro-magnets are attached to the bed-plate at their bases. to a are two exciting-coils, and b is the bed-plate.
Fig. 2 represents an electro-magnet of the same kind combined with a Gramme ring armature, also provided with radial teeth. The electro-magnet is not secured in the same way as the magnet in Fig. 1, being attached to the base-plate l) by one of its legs only. In this arrangement only one exciting-coil a may be employed.
Fig. 3 illustrates a multipolar machine in which the electro-magnets are arranged internally relatively to the armature, the plates or laminae being placed directly on the axis.
Fig. 4 shows the application of the improved system to the construction of a dynamo-electric machine in which the advantages of great compactness and small weight are combined. This arrangement of the parts will be readily understood on referring to the drawings.
Fig. 5 illustrates the application of the system to multipolar machines running at slow speeds.
In Fig. 6 the several laminae composing the field-magnets A and armature B are shown in section, being separated by washers b, of insulating material, suoh'as commonly employed for the purpose.
' Having now particularly described and aseertained the nature of this invention and in In testimony whereof I have signed this what manner the same is to be performed, I specification in the presence of two subscribdeclare that what I claim ising witnesses.
