Product Description:

The MSK100B-0300-NN-M1-BG1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion tasks in packaging lines, handling robots, and printing modules where accurate torque control and fast feedback are required. The motor combines servo response with precise position reporting, so the connected drive can correct speed and position deviations during repeated indexing, contouring, and start-stop cycles. This makes it suitable for axes that must maintain repeatable motion under changing load conditions.

Thermal management relies on natural convection, so the housing dissipates heat without forced airflow and can be used where fan maintenance is undesirable. Position feedback is exchanged over the Hiperface interface, which supports communication between the motor and compatible drive electronics through the encoder channel. Inside the encoder, an optical scanning system provides 128 signal periods per revolution, and the underlying sensing method is optical for stable signal generation. Because the encoder is a multi-turn absolute device, the motor retains revolution information after power loss and can return to operation without a homing move.

An electrically released holding brake provides 32 Nm of static torque to help keep suspended or vertical loads from drifting when the axis is stopped. The motor has a size of 100, which corresponds to a 100 mm stator diameter and gives a balance between inertia and continuous torque capacity. Torque is transmitted through a plain shaft that works with clamp or shrink-disc couplings, avoiding the stress concentrations associated with keyed shafts. The stator uses winding code 0300, and power is supplied through a connector on the B-side. The B-length housing extends the active stack while keeping the same mounting pilot, which helps the motor fit compact machine layouts.
