Product Description:

The MSK100B-0450-NN-S1-AG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This motor serves as the electromechanical actuator on numerically controlled axes, translating commanded current from a Rexroth drive into repeatable rotary motion for pick-and-place gantries, automated assembly stations, and other motion platforms. Its 100 mm frame and standardized mechanical envelope let machine builders integrate it into spaces where dynamic response and consistent torque accuracy are necessary.

Thermal management relies on natural convection, so heat generated in the stator is dissipated through the housing surface without forced airflow. This simplifies cabinet layouts but requires unobstructed ambient air around the motor body. Position and speed are measured by a high-resolution feedback assembly that uses the Hiperface digital interface. Inside this assembly, an optical scanning system produces 128 signal periods per revolution, and the sensor is a single-turn type, meaning it reports absolute shaft position for one full 360-degree rotation. Together, these features give the drive controller precise rotor angle data while keeping cable count low and setup straightforward.

The motor uses the standard MSK mechanical layout. Torque is delivered through a plain shaft, which eliminates keys and reduces runout when coupled with shrink-fit hubs. Power conductors are attached on the motor’s A-side, allowing cable routing to follow a consistent bend radius in multi-axis clusters. For applications that employ external load-holding or geared locking devices, the unit is supplied without a holding brake, which decreases mass and inertia at the shaft end. Electromagnetic characteristics are set by winding code 0450, so drive parameter sets must match this resistance and inductance profile to achieve rated current, speed, and field-weakening limits.
