The Bosch Rexroth Indramat MS2N series is designed for precision motion control in demanding industrial automation environments. These synchronous servo motors are used in machine tools, packaging systems, robotics, conveyors, and other motion applications where dynamic response, repeatable positioning, and compact power density matter. Across the MS2N family, buyers can find compact frame sizes for light, high-speed axes as well as larger motor options for heavier-duty servo applications.
For replacement sourcing, retrofit planning, and new machine builds, the MS2N platform gives engineers and maintenance teams a broad selection of frame sizes, winding options, encoder choices, shaft styles, and cooling methods. That flexibility makes the series useful when an application needs a close configuration match instead of a one-size-fits-all motor. If you are trying to identify the right Bosch Rexroth Indramat servo motor for your system, reviewing the frame-size group first is often the fastest way to narrow the search.
MS2N Synchronous Servo Motors Technical Overview

Bosch Rexroth’s MS2N platform couples rare-earth magnet rotors with a finely graded winding palette (BY 9 000 rpm to BD 1 000 rpm), letting machine builders size torque precisely while trimming envelope size by up to 30 %. The motors store calibrated saturation and temperature curves in EEPROM, so IndraDrive controllers can linearize torque output in real time – a prerequisite for precision printing, pick-and-place, and multi-axis CNC.
Beginning with size 07, optional axial fans or water-jackets let you trade footprint for duty-cycle, while the single-cable power/feedback option (M17 ↔ M23) slashes installation time in sizes 03-07. All models carry IP65 sealing, IEC 60034 insulation class F, and SIL-capable ACUROlink/Hiperface DSL encoders for safe motion profiles.
MS2N03 Synchronous Servo Motors
The MS2N03 frame is a compact servo motor class suited to very high-speed, low-inertia motion tasks. It is a strong fit for fast indexing, compact automation assemblies, and smaller motion axes where acceleration and responsiveness are more important than high continuous torque. In applications where space is limited but dynamic servo behavior is still critical, the MS2N03 frame is often one of the first sizes to consider.

MS2N04 Synchronous Servo Motors
The MS2N04 frame moves into a stronger compact-servo category for applications that need more torque than the smallest MS2N motors while still preserving quick response and installation flexibility. These motors make sense in light to mid-duty automation systems, including conveyors, assembly equipment, and smaller machine axes where compact dimensions still matter.
Part Number | M0 100 K (Nm) | Mmax 20 °C (Nm) | nmax (rpm) | Jrot (kg·m²) | Encoder |

2.00 | 6.40 | 6 000 | 1.1 ×10-4 | 128 ppr ST |
MS2N05 Synchronous Servo Motors
The MS2N05 frame is a useful mid-range option for buyers who need more output without moving into the larger motor classes too early. It fits many medium-duty motion-control tasks, including packaging equipment, material handling systems, and machine-tool subsystems that need a stronger torque reserve with controlled servo behavior.

7.15 | 22.6 | 6 000 | 2.9 ×10-4 | 20-bit ST |

MS2N06 Synchronous Servo Motors
The MS2N06 frame is a stronger MS2N option for buyers dealing with heavier machine loads, higher motion demands, and more substantial torque requirements. This size is well suited to more demanding CNC axes, larger conveyors, and other industrial motion applications where a compact motor is no longer enough, but a higher-output servo platform is still preferred over a much larger package.
Part Number | M0 100 K (Nm) | Mmax 20 °C (Nm) | nmax (rpm) | Jrot (kg·m²) | Encoder |
7.10 | 25.5 | 6 000 | 8.9 ×10-4 | 20-bit MT | |

7.10 | 17.3 | 6 000 | 5.0 ×10-4 | 20-bit ST |
MS2N07 Synchronous Servo Motors
The MS2N07 frame is intended for higher-load servo applications where the machine requires a significant step up in torque and thermal capability. At this size, the series becomes especially relevant for heavy automation axes, larger handling systems, and other motion applications where both sustained torque and high peak torque are important. This frame also opens the door to additional cooling configurations compared with the smaller sizes.
Part Number | M0 100 K (Nm) | Mmax 20 °C (Nm) | nmax (rpm) | Jrot (kg · m²) | Encoder |

28.2 | 79.7 | 6 000 | 0.0021 | 20-bit ACURO-Link |
MS2N10 Synchronous Servo Motors
The MS2N10 frame sits in the larger, higher-output portion of the MS2N family and is relevant for demanding industrial systems that need substantial torque and strong peak performance. This size is appropriate for heavier machine axes, robust production equipment, and applications where a servo motor must support larger mechanical loads with dependable control and higher thermal capacity.
Part Number | M0 100 K (Nm) | Mmax 20 °C (Nm) | nmax (rpm) | Jrot (kg·m²) | Encoder |

MS2N13 Synchronous Servo Motors
The MS2N13 frame belongs to the larger, high-capacity end of the MS2N synchronous servo motor family and is suited to industrial applications that demand elevated torque, strong acceleration control, and reliable performance under heavier operating loads. This size is a practical fit for robust machine axes, larger production equipment, and motion systems where a servo motor must deliver stable output, dependable responsiveness, and the durability needed for demanding automation environments.
Part Number | M0 100 K (Nm) | Mmax 20 °C (Nm) | nmax (rpm) | Jrot (kg·m²) | Encoder |
93.7 | 657 | 900 | 9.0 ×10-2 | 20-bit MT | |

MS2N Motors: Features That Matter
When sourcing an MS2N motor, the frame size is only part of the story. Encoder style, winding code, electrical connection, shaft execution, brake option, and cooling method all affect fit and performance. The MS2N family includes multiple encoder system families and connection styles, which is why exact part-number matching is usually the best starting point when replacing an installed motor.
The series also spans different protection levels and cooling options depending on the model. Smaller frame sizes are centered on self-cooling, while larger sizes add forced-ventilated and water-cooled configurations. That gives buyers more flexibility when the replacement motor has to fit an existing machine layout, environmental condition, or thermal requirement.
If you already have an MS2N part number, frame size, or damaged-nameplate reference, Indramat-USA can use that information as the starting point for matching the correct motor family. Whether you are replacing a failed unit, planning a retrofit, or trying to identify the right Bosch Rexroth Indramat MS2N synchronous servo motor for a machine build, beginning with the exact series and configuration code helps reduce downtime and ordering mistakes.
