Rexroth IndraDyn A Type Codes 6-1
6 Type Codes
6.1 Introduction
IndraDyn A is the general product name for Bosch Rexroth's housed
asynchronous motors.
The type code describes the available motor variants; it is the basis for
selecting and ordering products from Bosch Rexroth. This applies to both
new products as well as spare parts and repairs.
The following description gives an overview of the individual positions of
the type code and their meanings.
Note: When selecting a product, always consider the detailed
specifications in Chapter 4 ”Technical Data” and Chapter 9
”Application Notes”.
Definition
1. Product
MAD is the description of the blower cooled, housed asynchronous
motors.
MAF is the description of liquid-cooled, housed asynchronous motors.
2. Motor Frame Size
The motor frame size is derived from the dimensions of the output flange
and represents different power ranges.
3. Motor Frame Length
Within a series, the graduation of increasing motor frame length is
indicated by ID letters in alphabetic order.
Frame lengths are, for example, B, C and D.
4. Winding Code
The four-digit sequence of figures identifies the rated speed applicable for
the respective type of winding. The last figure is omitted. Example:
Winding ID 0200 stands for a rated speed of 2000 rpm.
5. Type of Cooling
MAD motors must always be operated with a fan whose air currents are
guided from the air guide plates over the surface of the motor ("surface
ventilation"). The air current is defined as "blowing" according to the
following figure.
