Product Description:

The MSK101D-0301-NN-S1-BG0-NSNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied under the MSK IndraDyn S Synchronous Motors series. The unit is intended for closed-loop motion tasks in industrial automation, where it delivers controlled torque and speed to conveyor sections, pick-and-place heads, or robotic joints. When paired with a compatible drive, it supports accurate positioning and stable speed regulation during repetitive machine cycles. High-resolution feedback allows the control system to react quickly to load changes and commanded motion updates.

This motor relies on natural convection to remove heat from the stator, so no forced-air or liquid circuit is required. Its frame size is 101, which gives the motor a larger magnetic cross-section than smaller MSK variants and supports higher continuous output with the D-length stator package. A housing sealed to IP65 helps keep dust and water jets away from the internal windings during direct machine mounting. Rotor position is reported through a Hiperface interface that carries digital data from an optical sensor head with 128 signal periods, supporting fine interpolation in the IndraDrive controller. The standard or explosion-protected version, winding code 0301, and thermal class 155 identify the winding arrangement, insulation system, and allowable hotspot temperature for this motor type.

The motor is supplied without a holding brake, so the load must be secured by external braking or drive-generated holding torque when power is removed. A permitted ambient range of 0–40 °C matches typical factory and cabinet conditions without derating. Mechanical power is delivered through a plain shaft, so torque is transferred through a clamped hub instead of an integrated key. All power conductors exit on the B-side of the stator housing, which can simplify cable routing in compact machine layouts. The single-turn encoder tracks one mechanical revolution before the position count repeats.
