Product Description:
The MSK100B-0300-NN-M2-AG1-RNNN is an IndraDyn S synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a precision drive element, it delivers closed-loop rotary motion for positioning tables, packaging axes, and other automated stations. It is intended for applications that depend on exact torque regulation and repeatable speed profiles.
This model uses natural convection for cooling, so generated heat is transferred to the surrounding air without auxiliary fans or liquid circuits. Feedback is routed through the EnDat2.1 interface, allowing digital transmission of position, temperature, and diagnostic data to the drive controller. The optical multiturn encoder provides a base resolution of 2048 signal periods, giving the control loop fine interpolation capability for smooth low-speed performance. With a housing rated IP65, the motor is sealed against dust ingress and low-pressure water jets, permitting installation on open machine frames. The motor uses winding code 0300, which matches the electromagnetic layout for this size-100, length-B frame and the corresponding MSK drive modules.
The electrically released holding brake supplies 32 Nm of static torque, so vertical or suspended loads can remain fixed when power is removed. A plain shaft simplifies coupling through backlash-free clamping hubs or shrink discs, while the power connector is mounted on the A-side to align cable routing with common cabinet layouts. Continuous service is permitted in ambient temperatures from 0 to 40 °C; outside this range, derating or forced cooling is required. The windings use insulation class 155, giving headroom for copper temperatures up to 155 °C before thermal limits are reached. Increased concentricity machining keeps rotor runout low, which helps minimize vibration when the high-resolution optical encoder is used for contouring or interpolated multi-axis motion.
