MHD Sychronous motors MHD Type Code 4-1
DOK-MOTOR*-MHD********-PR05-EN-P
4 MHD Type Code
Each order of a product by Rexroth must be based on the type code. All
available motor versions are uniquely described by their type code. The
following figure describes the individual characters of the type code
(abbrev. column) and their meaning.
