Product Description:

Bosch Rexroth Indramat manufactures the MSK050B-0600-NN-M1-UP1-NNNN servomotor in the MSK IndraDyn S Synchronous Motors series. This model occupies the 050 frame class in the range and is identified as a B-length variant, allowing a shorter motor where space behind the mounting flange is limited. In an automation cell, the motor converts electrical power from an IndraDrive amplifier into precisely controlled torque, driving indexing tables, small conveyors, or coordinated robotic axes that must accelerate rapidly and hold position without drift.

The stator jacket is cooled by natural convection, so no fan or liquid circuits are integrated and the motor relies on ambient air for heat dissipation. Service access is simplified because the feedback connector is rotatable through 240°, allowing the plug to be turned toward either side of the cabinet. Position and speed are exchanged with the drive over the Hiperface protocol, which supports identification and automatic parameter download. An optical encoder subdivides each mechanical turn into 128 signal periods, and this high increment count helps reduce velocity ripple during slow scans. Because the sensing element is optical, resolution is unaffected by external magnetic fields near high-current bus bars.

The feedback module not only resolves fractions of a revolution, but it also tracks up to 4096 revolutions with the multi-turn absolute function, so the axis powers up ready for motion. A shaft with a keyway provides a positive mechanical interface to couplings or pulleys, and an electrically released brake generates 6 Nm of holding torque to lock the rotor when the drive is disabled. Winding code 0600 indicates the voltage constant used with low-to-medium voltage IndraDrive supplies, and the standard housing design maintains IP65 sealing without external accessories. The compact housing helps keep inertia low, which supports shorter settling times during high-speed cycles.
