11-24 MHD112 MHD Sychronous motors
DOK-MOTOR*-MHD********-PR05-EN-P
11.6 Blower Units
MHD motors can also be delivered with optional blower units. Please refer
to the “Surface” column of the data sheets for performance data of
surface-cooled motors. The mechanical dimensions of the blower units
are represented in the dimension drawings. The possibilities of combining
motor and blower unit and the technical data of the blowers are
represented in the table below.
