[LB033174A], Letter from Thomas Alva Edison to Edison General Electric Co, Henry Villard, October 18th, 1889
Editor's Notes
"Replying to your letter 16th inst the trouble in the [unclear] Armature is not due to the winding-- ### Previously the burning out troubles occurred in the Field Magnet and not in the Armature. To rectify this trouble the very poor remedy of having Copper hobbling pieces in [unclear] magnet was adopted. This diminished the counter-electromotive force at any one moment so derived from the charge or discharge of the magnet that the disruptive change was prevented—But it was this very charge that saved the armature and now being done away with, the whole of the current comes to the armature like a cannon ball unchecked by the back current of the field—the consequence is that with heavy loads on [unclear] the armature must burn out even if wound with absolute perfection." Yours truly [signed] TAE
