The Bosch Rexroth IndraDyn A MAF series consists of liquid-cooled asynchronous servo motors intended for applications that demand very high torque and power density in a compact motor package.

About
Type Code Breakdown
Common Ordering Codes

A key design focus is the liquid-cooling concept, which is engineered to thermally isolate the motor from the machine structure to help maintain handling and machining precision while sustaining high continuous performance. The series supports high output capability across its range, with rated power levels reaching into the triple-digit kilowatt class, maximum speeds up to about 11,000 rpm (depending on the bearing/version), and a high protection category suitable for industrial environments (IP65). For integration and serviceability, the cooling connections can be supplied with quick-coupling hardware that incorporates leak-proofing to simplify maintenance and reduce downtime during motor replacement or service. Configuration options include holding brakes, multiple encoder system choices, selectable vibration severity grades, and different shaft versions so the motor can be matched to the specific axis dynamics and mechanical interface requirements.

Type code position / field	What it means	How it appears in the code	Valid / shown values in the manuals
1) Product family	Motor family identifier (IndraDyn A housed asynchronous motors)	`MAF`	`MAF` = liquid-cooled housed asynchronous motor (IndraDyn A)
2) Motor frame size	Size class derived from output flange dimensions / power range	`MAF100…`, `MAF130…`, `MAF180…`	Examples referenced include sizes such as `100`, `130`, `160`, `180`, `225` (availability depends on series)
3) Motor frame length	Length variant within the same frame size	`MAF100C…`, `MAF180D…`	ID letters in alphabetical order; examples include `B`, `C`, `D`
4) Winding code	4-digit winding ID that identifies the rated speed for that winding (last digit omitted in the ID)	`-0100-`, `-0200-`, etc.	Example: `0200` corresponds to a rated speed of 2000 rpm
5) Cooling requirement (MAF)	MAF motors require an external cooling system	Not an option code (a requirement)	External cooling system required (not included)
6) Cooling system connection	How the coolant circuit connects to the motor	`-FQ-` or `-FR-`	`FQ` = connection thread; `FR` = quick coupling
7) Vibration severity grade	Balancing / vibration grade selection	Shown as a numeric grade in the ordering guide	`1` = A, `3` = B, `4` = C
8) Encoder (feedback)	Encoder type (if equipped)	`-S2-`, `-M2-`, `-C0-`, `-S6-`, `-M6-`	`S2` = single-turn EnDat 2.1 (2048 periods); `M2` = multi-turn EnDat 2.1 (2048 periods + 4096 rev abs); `C0` = incremental (2048 increments); `S6/M6` = EnDat variants for potentially explosive atmospheres
9) Bearing assembly	Bearing package option	Typically a single letter in the “options block”	`N` = standard; `A` = fixed bearing A-side; `H` = high-speed; `V` = heavy-duty (reinforced)
10) Electrical connection style / position	Whether the motor uses a plug (socket-outlet) or terminal box, and where it’s oriented	Letter in the “options block”	Plug position: `A` (A-side), `B` (B-side), `L` (left), `R` (right). Terminal box turntable: `E` (A-side), `H` (B-side), `G` (left), `D` (right).
11) Construction (mounting)	Mounting / frame shape	`-05-` or `-35-`	`05` = flange-mounted; `35` = flange-mounted or foot-mounted
12) Holding brake	Brake presence/type	Typically a digit in the “options block”	`0` = no brake; `1` = electrically released brake; `3` = electrically released heavy-duty brake; `5` = electrically clamped brake
13) Shaft version	Shaft style and sealing	Shaft letters (shown as options)	Plain shaft: `H` (no seal ring), `G` (with seal ring/IP65), `F` (labyrinth seal). Keyway: `Q` (no seal ring), `P` (with seal ring/IP65), `R` (labyrinth seal).
14) Notes on code grouping	Some options are grouped into a combined “options block” in the ordering string	Example block like `…-S2-AH0-…`	The manuals present bearing/connection/brake (and related options) as selectable positions that are encoded together in the ordering string.
