Product Description:
Bosch Rexroth Indramat produced the MSK070D-0150-NN-M2-UG0-RNNN for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts controlled three-phase power from a drive into exact angular displacement required by precision axes in packaging lines, handling gantries, and printing machinery. The motor integrates an absolute optical encoder so the drive can determine rotor position at power-up and command closed-loop motion without external sensors. This arrangement supports accurate starts, stops, and repeated indexing while maintaining stable velocity regulation throughout production cycles.
Heat generated in the stator is removed by natural convection, so no blower or liquid loop is required and the housing can operate without external cooling hardware. A 240° rotatable encoder connector lets the cable exit be aligned with the machine envelope and helps reduce bend stress at the connection point. Position data moves over the digital EnDat2.1 interface, enabling bidirectional exchange with the drive for feedback and initialization. The measuring system uses an optical principle with 2048 signal periods, allowing the controller to interpolate fine position values for smooth speed control. Increased concentricity at the shaft shoulder helps support precise coupling alignment and stable rotation in applications that demand repeatable motion.
The motor uses frame size 070 with D length housing, which provides additional active copper for winding code 0150 while keeping the overall diameter compact. Its feedback device is the multiturn absolute variant, so stored revolution data makes homing unnecessary after power loss. The unit is supplied without a holding brake, which lowers rotor inertia and supports faster acceleration in dynamic axes. A hardened plain shaft supports press-fit couplings and avoids keyway imbalance during rotation. This shaft arrangement suits direct-coupled mechanisms that require accurate transfer of torque and stable running at varying speeds.
