Product Description:
The MSK030B-0900-NN-S3-UG1-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The motor has size 030 with B length code, giving a compact form factor for multi-axis gantries, pick-and-place stations, and other small servo axes where installation space is limited. As a drive component, it converts controlled electrical input from a compatible inverter into mechanical rotation so tooling, conveyors, or indexing tables can follow precise motion profiles. It is used where fast starts, stops, and repeatable positioning are required by the machine cycle. Its compact format also helps when moving structures must be kept light to limit inertia.
Thermal management relies on natural convection, and the housing is rated IP65, so dust and low-pressure water jets are kept away from the windings during normal industrial use. A rotatable 240° encoder connector simplifies cable routing and provides the Hiperface interface to the drive for start-up and continuous position feedback. Inside the encoder, a resolution of 16 signal periods is generated per mechanical revolution, and the feedback operates in single-turn mode with a center-aligned sensing track. Motion can be held at rest by an electrically released brake that provides 1 Nm of static torque. The encoder and brake functions are integrated into the motor housing, which helps keep the axis package compact.
The feedback device uses a capacitive sensing principle, which helps resist magnetic and optical interference across the motor speed range. Mechanical output is delivered through a plain shaft, making the motor suitable for backlash-free clamp couplings often used on small servo axes. Continuous duty is permitted at ambient temperatures of 0–40 °C, and Class 155 insulation supports winding temperatures up to 155 °C. The winding code 0900 is paired with the standard design classification used for this motor. It is suited to small transfer units, feeders, and indexing mechanisms that need stable servo feedback.
