The construction is very similar to, andpossesses all the advantages of that employed in the gen-erator armature previously described. There is no pulleyor external mechanical connection on this FIG. 89. BUCKER FIELD COILS AND POLE PIECES. Field Magnets.—The field is of the bipolar, iron cladtype. Each armature core revolves between two salientpole pieces, which are bolted into the casing, and consistof a pole shoe and core.

The pole pieces are placed ina vertical line, so that one pole and coil for each armaturecore is in the upper, and one in the lower part of the ma-chine. Brush Holders.—The brush holders are mounted rig-idly in the upper half of the machine. The springs andfingers are interchangeable with those of the taking off the bottom half of the casing, or in remov-ing the armature, no wire connections need be disturbedbeyond disconnecting the upper and lower field leads.
