Product Description:

The MSK071F-0302-NN-S1-UG0-NNNN is a synchronous servomotor in the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. As a compact rotary drive element, it converts controlled electrical energy into torque and speed for positioning axes and cyclic motion stages in automated machinery. The motor integrates with IndraDrive controllers through a digital feedback channel, allowing precise current, velocity, and position loops that are essential for packaging, printing, and general handling equipment. Classified as an IndraDyn S synchronous servomotor, it is intended for closed-loop servo systems where high dynamic response and repeatable accuracy are required.

The mechanical structure follows the standard 071 frame, and heat is dissipated by natural convection, so no external fan is required when the unit is fixed to a thermally conductive plate. The aluminum housing carries an IP65 rating, sealing the stator against dust and low-pressure water jets. Continuous duty is allowed from 0 to 40 °C, matching the ambient range expected in industrial installations. Torque is transmitted through a plain shaft, which is compatible with clamp couplings. For installation flexibility, the feedback connector can be rotated through 240°, which simplifies cable routing in tight spaces.

Position feedback is supplied by an encoder that communicates over the Hiperface serial interface, enabling absolute data exchange with compatible IndraDrive controllers. Inside the encoder, an optical scanning head reads a disk that provides 128 signal periods, delivering fine angular resolution at the controller input. The sensing chain is implemented as a single-turn system, which reports one absolute position per mechanical revolution while the drive stores multi-turn counts. The motor ships without a holding brake, which reduces rotor inertia for quicker acceleration. Its Class 155 insulation protects the windings when the housing warms during peak cycles.
