More torque, higher speeds, the practical single cable connection and an extensive range of options: This generation of MS2N motors by Rexroth combines high dynamism with compact dimensions and best energy efficiency. Rotors with low and medium inertia are available with optimum mass customization. For intelligent solutions in the Industry 4.0 environment, MS2N motors serve as data sources.

The new generation of Bosch Rexroth MS2N synchronous servo motors

With more than 50 motor types, the MS2N motor series from Bosch Rexroth covers maximum torques of up to 360 Nm and maximum speeds up to 9 000 rpm. By means of an optimized electromagnetic design and motor construction, a high power density is achieved. With the finely graduated torque and speed range, application-compatible encoder options and optional single cable connection, the motors flexibly comply with the diverse requirements of modern automation. Forced ventilation and water cooling open up new power ranges.

Intelligent within the system

In the MS2N series, the intelligence makes its way right to the motor. The individual measurements of each individual motor as well as the saturation and temperature data are stored in the respective motor data memory and are processed by IndraDrive control in real time. This increases the torque accuracy considerably and reduces the tolerance range during operation to a fraction of the previously usual values. This allows the servo motor to be used as a reliable sensor and data source. In this way,
applications in the Industry 4.0 environment can be implemented cost-effectively and without additional components.

Self-cooled, force-ventilated or water-cooled

Motors with integrated fans or water cooling are available from sizes MS2N07. This considerably improves the continuous power with the same size. The blower motors have degree of protection IP65, an integrated temperature sensor with UL-certified intrinsic safety and optionally 115 V or 230 V connection voltage. Water-cooled motors offer increased continuous torques and ultra-high power density, ideal for new machine concepts with minimal space requirements and high demands on effective heat dissipation. The robust design of the entire motor cooling in stainless steel enables easy and reliable integration into a wide range of cooling circuit systems.

Key features of the MS2N series:

– Max torque up to 360 Nm;
– Max speed up to 9000 rpm;
– Increased continuous power due to optional forced ventilation and water cooling;
– Encoder option with SIL3 / Ple safety certificate;
– Connection with a single cable simplifies installation: cable length up to 75 m without additional components.

As part of the MS2N series, we offer:

  • models with self-cooling – from 7.4 Nm to 360 Nm, from 6000 to 9000 rpm
  • models with forced ventilation – from 140 to 360 Nm, max.speed – 6000 rpm
  • models with water cooling – from 140 to 360 Nm, max.speed – 6000 rpm
