The type code describes the available motor variants. The type code is the
basis for selecting and ordering products from Bosch Rexroth. This applies to
new products as well as to spare parts and repairs.
The following descriptions give an overview of the individual digits of the type
code ("Abbrev. column") and their meaning.
When selecting a product, additionally consider the detailed spec‐
ifications in the chapter 4 "Technical data" and chapter 9 "Notes
regarding application".
MAD is the name of the series of air-cooled asynchronous housing motors.
MAF is the name of the series of liquid-cooled asynchronous housing motors.
The motor frame size is derived from the mechanical dimensions of the
flange on the output side and represents different power ranges.
Within a series, the grading of increasing motor length is indicated by ID let‐
ters in alphabetic order.
For example, frame lengths can be B, C and E.
The four-digit numerical sequence indicates the rated speed which applies to
the respective winding variant. The last digit is omitted. Example: Winding
designation 0200 means 2000 min
MAD motors always have to be operated with a fan. Air baffles guide the air
currents of this fan over the surface of the motor ("surface cooling").
Operation without cooling is prohibited.
There are two options to cool MAD motors:
● Option "SA": Cooling via the mounted axial fan. The air current is de‐
fined as "blowing" according to the following figure.
