notes: label: Description (Brief)
content: Tag top of motor reads: "Crocker Wheeler Electric Co., N.Y. / 10 H.P./ Type 10-C / No.1 / Speed 860 / Volts 230 Amp 36". This is a bi-polar machine having pole pieces above the field magnets. This mounting arrangement permitted maximum magnetic flux concentration through the armature. The armature has a drum type construction with commutator on the shaft. Four carbon brushes are used in a rigging which permits adjusting of brush tension by springs. This machine was manufactured in New York City in 1889. Commutator is in excellent condition. However, one pedestal plate is made of wood--apparently the original was broken. Oil feed cups are mounted on a pedestal on each side of the shaft. Reference: Electric Power, August 1892. Front page drawing. (Brush rigging is different in this model).
