II il quite possible that several of those
who read these lincs may never have
seen an electric motor, yet it is none The
less true that there are 10 day already in
operation in this country oyer 10000
electric motors ot various sizes engaged
in IN endless variety of occupations.
One company building motors reports
that its machines are new employe1 in
nearly 200 distinct industries, AID that
rev uses are found daily. This develop
ment has becn seen almost entirely with
f, in the last three years.
From 1880 up to 1857 electrical engi-
neers aud contractors have giyer their
attention mainly to The installation of
electric lighting plants iii American
towns and cities, With the result that
there were sGmc 200 centra! stations in
operation supplying the arc lgl. o. the
incaudcscant ii@h:, and sometimes both.
4 great many Of these stations paid we'll
from the start, but it was soon found that
the lighting business was after ali lim!.
tct! one-.:.at is, Il could Only be carried
Oh during the hours CT darkness, 80 That
valuable plant often Jay IDLE sixteen or
cirhteen hours cut of Tic twenty four.
Yet the current which such & plan. could
generate woalt! lend itself as readily TO
driving au electric motor as to furnishing
light in lamp, and the same c;rcui.
that conveyed to the LAMPS would also
convey it to the motors.
Itwas this fact that gave greats.imu-
lus to the electric motor industry about
three years ago, and led 10 The pe.fecting
Of what had Heretofore beena very crude
and cumbersome piece OF mechanism.
AS is nov YerJ generally known, the
electric motor has but one moving part,
the revolving armatuTe, and by aleans of
pulley placed at the end Of the arna-
ture shaft its power can be applied to
any piece of apparatus or machinery
known to the s-!a. utup to 1856 nearly
all the electric motoTs lad been badly
designed and poorly built, aac! the cur.
rent that should have been converted
into power was simply wasted in devel-
oping heat, 50 that the machines rapidly
burnt out and otherwise became useless
and we're altogether too expensive to
run.
at the present time, however, there are
several electric motors in the market CT
excellent design ard workmanship for
which as high an efficiency as over 30
per cent. is claimed, end there cen be no
doubt that the rate of efficiency in the
smaller sizes as well as il the larger is
the highest that has yet been attained
by any piece of power transmission ma
chine.y. Thus an electric motor OF onc.
half or one quarter horse power will
easily show AS high an efficiency as that
of another sort OF motor OF ten or fifteen
horse power, yet nobody dreams oi ex.
pecsing (. Gas engine or steam engine
of one quarter or one half horse power 10
give anything but small return upon
the fuel applied to it.
Moreover, with the electric motor aa
enormous advantage Las been the fac:
that when it has been installed and coz
nec:ions have beer made with the Cir
cults connecting i!wilh the central sta
tioi!, it is practically ready that minute
for work. al that is necessary is the
turning Of switch and the cnrren. is
instaDtansously there. With the steam
engine. even when the steam is taken
from the steam mains in the street, can.
siderable attendance is necessary. and in
the yaa. majority of instances the steam
has to be manufactured on tie spot, 50
that boilers are necessary. involving the
attendance Of an expert engineer, the
supply of water and coal and the removal
of ashes. Such steam plants s'sr occupy
considerable space and throw oil! 10 small
amount OF beat.
The idea, however, with the electric
motor is to concentrate il g central sta.
ton all the Inconvenience connected
with The generation Of steam and 10
transmit the energy in the form OF cur.
rent, so tia; ail the user has to do il: to
draw eli .!Ic supply as he wants i. just
aa lie would do in turning 9 tap to pro-
cure supply Of water.
New York city, to 20 no further, far,
nishes many interesting examples g. the
manner in which electric motors isTc
been applied to variety of uses.
Wherever tie circuit, pass the; are tap
pe. icr paweT purposes, and thus tie
central staten, which furnishes current
at night To- Fighting, is supplying CIR.
ren. in the e,;iy time Ger power In the
lower part Of tho ely i@:gc number Of
motors are i'll Use. These arc generally
emp!oyed for ventilation purposes, t!.ough
not few may be found running freight
and passenger elevators. i large Tum-
Der in the section below Chamuers street
arc also 10 be iourd in printing Offices.
In that section, too, and elsewhere the
motors are cmriovod in :; variety Ct
other work, src! IS driving gangs VI
sewing machines, saw mills, machine
shops, drug mills. pumps, ice cream
freezcrs and the like.
In one OF tho large confectionery TAG
tories the electric motors grind Up all
the chocolate and o.herraw material. y
ar@e number of motors afa uscG BY
dentists to run their latics and cthc;
