D.72738, Frame and Field Winding, for use on the 40-50 H.P. Dynamo, 48 Coil, higher output machine. The only difference between this and a standard machine is the fitting of the pole which gives a tapering air gap, Blue Prints of which you have received some time ago; therefore, will you please put in hand two Dynamos to the following L.O.P.s. D.72238 Armature. D.71613 Bearing Brackets. D.72244 Commutator. D.72738 Frame and Field Winding. BY/RD. Recd ✓ | ||
