Product Description:

Bosch Rexroth Indramat manufactures the MSK070D-0150-NN-S2-UG1-RNNN as part of the MSK IndraDyn S Synchronous Motors series. The motor converts electrical power into regulated mechanical motion for indexing tables, packaging machinery, and other CNC axes that demand precise dynamic response. When paired with a compatible drive controller, it supports accurate positioning, controlled acceleration, and stable holding behavior during repeated motion cycles. This makes the unit suitable for servo applications that require repeatable starts, stops, and short settling times under changing loads. Its construction integrates an optical feedback system and an electrically released holding brake so the driven load can be clamped at standstill without power.

This D-length, size 070 unit relies on natural convection to remove heat generated by copper losses, eliminating the need for external fans or coolant lines. A housing rated IP65 prevents dust ingress and protects against water jets, allowing direct mounting outside a control cabinet. The sealed housing also helps protect internal components in dusty or wet machine areas. The electrically released brake delivers 23 Nm of static torque to keep vertical or suspended loads secure. Position data travel through the EnDat2.1 serial interface, and the optical disc provides 2048 signal periods, giving the drive controller fine interpolation capability for smooth speed loops.

The feedback connector can be rotated by 240° for flexible cable routing, and the rotor is manufactured with increased concentricity to reduce radial runout on high-precision shafts. Encoder scanning is optical and supports a single-turn absolute position field, while the rotatable plug helps route the feedback cable in tight machine spaces. The winding code 0150 matches the electrical characteristics expected by the drive, and Class 155 insulation supports operation within the stated 0 to 40 °C ambient range. A plain shaft with a factory-ground surface eases coupling to gearboxes or belt pulleys, and that shaft style works well with common clamping hubs and precision couplings.
