MSK100B-0300-NN-M2-RG0-RNNN

The MSK100B-0300-NN-M2-RG0-RNNN servo motor from Bosch Rexroth Indramat embodies the robust design of the MSK IndraDyn S Synchronous Motors series, featuring a Winding Code of 0300 and precisely four pole pairs for balanced torque output. With a Product Type designation as an IndraDyn S synchronous servomotor, it supports both horizontal and vertical mounting orientations at a minimum ambient operating temperature of 0 °C. The motor’s Motor Size of 100 and Motor Length rated “B” ensure predictable envelope dimensions for system designers. A substantial rotor moment of inertia of 0.01920 kg·m² contributes to stable dynamic performance, while the absence of a Holding Brake reduces mechanical complexity. Its Power Connector is located on the right side, simplifying cabling in compact installations.

The MSK100B-0300-NN-M2-RG0-RNNN delivers precise motion control through its integrated Encoder Technology: an optical, multi-turn absolute encoder with the Encoder Interface EnDat 2.1. This encoder provides Encoder Resolution of 2048 signal periods per revolution, capturing absolute and indirect positions across 4,096 mechanical rotations with system accuracy of ±20 angular seconds. Drive performance is governed by a Continuous Current at Standstill 100 K of 20.5 A and Continuous Torque at Standstill 100 K of 33.0 Nm, while peak demands are met by a Maximum Current of 78.3 A and Maximum Torque of 102.0 Nm. The stator winding exhibits an inductivity of Winding Inductivity 5,500 mH, contributing to torque stability under rapid current fluctuations. Heat dissipation is managed by Cooling via natural convection, transferring thermal energy both into ambient air and the machine structure.

Engineered for reliable integration, the motor employs a Plain Shaft with a DIN 6885-1 sealing ring, offering a zero-backlash shaft-hub connection and compliance with DIN 42955 for concentricity and runout tolerance. The housing features a black RAL 9005 2K epoxy resin coating, resistant to dilute acids, sewage, and mineral oils, with limited protection against hydraulic oils and organic solvents. Designed for seamless pairing with IndraDrive control units, it supports flexible servo drive configurations in demanding applications. Typical use cases include robotic actuation, machine tools, material handling systems, printing and paper processing machines, and metal-forming equipment where precision, durability, and easy integration are critical.
