Excerpt from The Application of Electric-Motors to Machine-Driving, Vol. 1
The following pages, originally a serial in Electricity, have been entirely re-written and brought up to date. The rapid progress in this branch of engineering has rendered this necessary, indeed when the first edition appeared, almost all of the apparatus herein described had not even been designed, and though there, were many installations of electric power, these were in shipbuilding yards and engineering works, where the machinery was scattered and consequently the direct results of electric driving, viz., saving of fuel and distribution losses, were most obvious.
With the extension of the applications of the electric motor came a gradual recognition of the collateral advantages which, in many cases, result in a larger saving than may be obtained from the mere distribution of power as such. It has been the authors aim, not only to illustrate the various applications of electric motors in our leading industries, but to indicate, as far as possible, these indirect advantages, which should invariably receive a large share of attention when electric driving is contemplated, though after many years experience, the author fears that, in many cases, the economic advantages of electric power have not been completely realised in industrial establishments.
