Product Description:

The MSK101D-0450-NN-M1-AG0-NNNN is a synchronous servo motor developed by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Serving as an electromechanical actuator, it converts drive-controller output into rotary motion for positioning axes, packaging stations, and other automated equipment. Used with a compatible drive, it supports accurate speed control, repeatable positioning, and responsive torque delivery during cyclic motion tasks. It is suitable for servo-driven applications where motion sequences must remain consistent across repeated starts, stops, and speed changes.

Heat is removed from the frame by natural convection, so cabinet airflow or liquid circuits are not required. This cooling method keeps the installation simpler and avoids extra external cooling hardware. The stator uses winding code 0450, and that electrical layout is paired with motor size 101 and length D to support medium-power axes with a practical balance of torque and inertia. A plain shaft exits the front bearing for direct coupling to gearboxes or pulleys without keyways, while the power connector is mounted on the A-side to help separate high-current cabling from adjacent feedback leads and cooling surfaces. This shaft style is commonly used where torque is transferred through a clamping hub or a similar friction-based coupling. The motor uses the standard series design without special coatings or nonstandard dimensions.

Position feedback is supplied through a Hiperface interface that carries both incremental and absolute data over two shielded pairs. The sensing element is optical, which supports precise rotor position detection, and it resolves each mechanical turn into 128 signal periods. Because it is a multiturn absolute system, multiple shaft revolutions remain stored for startup reference after power cycling. The combined feedback arrangement allows the controller to read rotor position during startup and maintain stable commutation during operation. The motor ships without a holding brake, so any static load must be held by the drive or by an external mechanical device. This arrangement suits servo axes that need closed-loop feedback and controlled stopping behavior.
