Product Description:

The MSK100B-0450-NN-S1-LG1-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and speed control in automated machinery where high dynamic response and precise feedback are required. By pairing an optical single-turn encoder with the drive, the motor returns absolute position data to the controller so axes can be held or moved accurately during coordinated motion profiles.

This model dissipates heat to ambient air through natural convection, so no external fan or liquid circuit is needed. Feedback signals leave the motor through a Hiperface interface, and the embedded scale delivers 128 signal periods per mechanical revolution; the Optical scanning principle maintains consistent resolution during operation. A spring-applied, electrically released brake supplies 32 Nm of static holding torque to secure vertical or suspended loads when power is removed. Protection against dust ingress and water jets is provided by the IP65 housing rating, allowing cabinet-free mounting in most industrial spaces. The plain shaft, length code B housing, and 100 frame size follow the standard mechanical design of the series, and winding code 0450 tailors the stator for medium-torque applications.

The operating range spans 0 to 40 °C, so continuous output is available in typical shop floor conditions without derating. Power and brake conductors exit on the left side, which can simplify cable routing when the motor is installed on gantry cross rails or conveyor drives. Thermal stability is supported by insulation class 155, giving ample margin between winding temperature rise and the insulation limit. The shaft interface eases coupling to gearboxes or timing-belt pulleys, and the encoder supports accurate reference handling during startup. The enclosed housing also helps protect internal laminations during routine washdowns.
