Product Description:

The MSK100A-0450-NN-M1-BP1-NNNN belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. It is an AC servomotor intended for closed-loop motion axes in industrial automation, where position accuracy and repeatable torque are required during synchronized movement. By combining a permanent-magnet rotor with a high-resolution optical encoder, the unit supplies feedback that drive controllers use to regulate speed and angle during packaging, material handling, and machining tasks. It is suited to machines that need accurate positioning over repeated operating cycles.

This motor is cooled by natural convection, so ambient airflow removes heat without added fans or liquid circuits. Because cooling depends on the housing surface, heat dissipation is tied to surrounding airflow and available mounting space. Feedback is delivered over a Hiperface interface, giving digital position data during each control cycle. The optical reader distinguishes 128 signal periods per mechanical revolution, and its scale supports a multiturn absolute count so the controller retains shaft position information after power loss. An electrically released holding brake applies 32 Nm of static torque, and the motor uses the standard mechanical design code.

The motor has frame size 100 with length code A, so its mounting dimensions match other MSK units of similar footprint while keeping inertia comparatively low. A shaft with a keyway provides secure torque transmission and simplifies coupling to legacy gearboxes. The keyed connection is useful where the driven load must resist slip during changing torque conditions. All three phase conductors terminate on the B-side connector, which helps reduce cable bend radius inside tight enclosures. Internal wiring matches winding code 0450, which corresponds to resistance and inductance values used with compatible IndraDrive power modules.
