The cut herewith shows the new line of generators being manu-factured by The Ideal Electric and Manufacturing Company, Mans-field, Ohio, and is known as its Type D, ranging in capacityfrom 25 to 150 kw. They are four pole up to and including 40kw, slow speed; the larger machines being of six pole design. Themagnet frame is of soft cast iron divided horizontally in all sizesand with forged steel magnet poles of circular cross section castwelded into the frame so as to insure an absolutely perfect mag-netic joint. These poles are provided with cast-iron shoes whichprotect and support the field windings and embody the special feat-ures of this construction in reducing the density of the magneticflux where it enters the
