12.6 Blower Units
MHD motors can also be delivered with optional fan units. Please refer to
the “Surface” column of the data sheets for performance data of surface-
cooled motors. The mechanical dimensions of the fan units are
represented in the dimension drawings. The possibilities of combining
motor and fan unit and the technical data of the fans are represented in
the table below.
