Product Description:

The MSK040B-0750-NN-S1-UG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is used as a compact drive element for automated pick-and-place axes, carton erectors, and light machine-tool feeds where fast position loops and stable velocity are required. In this role, the motor converts controlled current into rotary motion for short indexing moves and repeatable point-to-point positioning. Direct coupling of the rotor to the mechanical load helps limit compliance, and the motor’s single-cable option simplifies cabinet wiring in distributed servo systems.

The motor has frame size 040 and length code B, giving a short housing that fits tight mounting zones. Heat is removed by natural convection, so the mounting surface must allow unobstructed airflow around the housing. Because cooling is passive, the installation does not require added fan hardware at the motor body. A plain shaft simplifies integration with clamp hubs or custom couplings, and there is no keyway that could introduce concentricity errors. The motor is supplied without a holding brake, so axes that need static load retention must rely on drive torque or external clamps.

A rotatable 240° connector lets the cable exit in the preferred direction, which can reduce strain in articulated carriers and help route the cable around nearby guards or tooling. Position data travel over the Hiperface interface, and the encoder uses optical technology with a base resolution of 128 signal periods per revolution. This arrangement supports commutation and stable speed feedback during low-speed motion as well as normal running conditions. Because the encoder is single-turn, the controller receives absolute position within one mechanical turn. Multi-turn counting can be handled in the drive when needed, and the standard enclosure design does not add extra sealing rings.
