S2N motors – intelligent, powerful, flexible

The new-generation MS2N motors from Bosch Rexroth combine high power dynamics with a compact design and excellent energy efficiency.

With a single, practical cable connection, the MS2N saves space, weight, costs and time of installation, and can be flexibly integrated into your industrial automation application. Self-cooled, forced ventiliation and water-cooled motors are available as required by your application. Rotors with low and medium inertia are available with optimum mass customisation.

Used within the Bosch Rexroth IndraDrive control architecture, the MS2N servo motor offers a reliable sensor and data source with real-time processing capabilities.

  • High torque density, increased speed range, high energy efficiency
  • Torque from 3.8 to 360 Nm
  • Max. motor speed: 9 000 rpm
  • New encoder option with certified safety up to SIL3 PLe

MSK motors – for all drive requirements

MSK servo motors provide a wide power spectrum and narrow size increments. They offer high torque density with a compact design that achieves max. torque of 631 Nm and max. speeds of 9 000 rpm.

The MSK is available in self-cooled, forced ventilation and water-cooled versions as required by your application. An ATEX option as per directive 94/9/EC is also available for zones with flammable gas (Ex II 3G Ex nA T155°C Gc X) and flammable dust (Ex II 3D Ex tc IIIC T155°C Dc IP6X X).

Depending on the level of precision required, we can supply the motors with encoder systems for standard or high-precision requirements in single and multi-turn configurations. A number of further options, such as the shaft keyway, holding brake and reduced runout are also available.

  • Torque from 4 to 631 Nm
  • Motor speed from 3 200 to 9 000 rpm
  • Encoder systems for a wide and diverse range of applications
  • High protection category IP65

MKE motors – for potentially explosive areas

Bosch Rexroth’s MKE motors are designed for use in production plants susceptible to explosive mixtures of air and flammable gases, vapours, mist or dust.

The range includes various motor sizes with flameproof enclosures, all ATEX certified and/or UL/CSA compliant. Optional extras such as holding brakes, keyway and single- or multi-turn encoder systems are available.

These synchronous motors are certified in accordance with Directive 94/9/EC ATEX95 (II 2 Gd IIB T4 or II 2D Ex tD A21 IP6x T135°C) and Class I, Groups C and D as per UL508C, UL674 and UL1446.

  • Max. torque: 187 Nm
  • Max.  motor speeds: 9 000 rpm
  • Encoder systems for a wide and diverse range of applications
  • Pressure-resistant encapsulation
  • Compliance with ATEX and UL/CSA

MSM motors – for compact drives

Synchronous MSM servo motors are available in five sizes rated at up to 750 W continuous mechanical power. These motors pack a high power density into a compact, short-length and robust construction, with minimised flange dimensions that make them ideal in diverse automation applications with limited space.

These IP54-rated motors come with an absolute encoder and optional holding brake. They are for use with the IndraDrive Cs servo drives with 3 AC 230 V power.

  • Torque from 0.95 to to 7.1 Nm
  • Motor speed 4 500 – 5 000 rpm
  • Multi-turn absolute encoder
  • Dynamic motor performance
  • High power density
