Product Description:

The MSK100B-0450-NN-M1-AG0-NNNN belongs to the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. It is an IndraDyn S synchronous servomotor intended for closed-loop positioning and speed control in automated machinery. This type of motor is commonly used on axes that require repeatable rotary motion, including transfer units, packaging equipment, and handling systems. The housing layout follows the standard mechanical format of the series for direct integration with driven equipment. Because it is delivered without a holding brake, any static load holding must be handled by an external mechanism or by the drive.

The housing relies on natural convection to remove heat, eliminating the need for forced airflow. A protection level of IP65 seals the stator against dust ingress and water jets encountered on a factory floor. The motor uses a plain shaft, which allows direct coupling to gearboxes or other driven elements without keying. The active frame has a motor size of 100 with length designation B, and power cabling is routed on the A-side of the stator. The winding code 0450 matches the electrical values expected by compatible Rexroth drive controllers. Because cooling is passive, installation does not require separate fan wiring or external airflow hardware.

For feedback, the motor integrates a Hiperface interface that transmits position data through a single hybrid connector. The optical encoder produces 128 signal periods per mechanical revolution and is built as a multi-turn absolute device, allowing the drive to recover position over 4,096 turns without homing after a power loss. Continuous operation is rated for an ambient range of 0 to 40 °C. The insulation system is rated as Class 155, allowing winding temperatures up to 155 °C before thermal limits are reached. Absolute feedback supports accurate restart behavior after controlled stops, and optical scanning helps maintain stable motion feedback over standard motor cables.
