Product Description:
The MSK101E-0300-FN-S1-BG2-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Intended for servo axes in packaging machines, handling modules, and processing centers, the unit converts commanded current into controlled rotary motion while providing precise position feedback to the drive controller. Its compact frame and closed construction allow installation inside cabinets or directly on machinery where space and cleanliness are priorities. This arrangement supports controlled acceleration and repeatable stopping during indexing, transfer, and positioning tasks.
An FN cooling circuit is mandatory, and the stator is configured for liquid cooling, so heat is removed independently of ambient airflow. Frame size 101 and length E set the active stack geometry, while winding code 0300 provides electrical characteristics suited to high-response servo duty. Insulation rated for class 155 permits continuous current without thermal degradation. The integrated feedback system uses a Hiperface interface with 128 signal periods per revolution; the disk is read by an optical sensor array in a single-turn configuration, giving absolute position immediately after power-up. A B-side power connector directs motor leads away from the load side and simplifies cable routing in tight enclosures. Because cooling does not depend on cabinet air movement, the motor can be placed in dense machine layouts without requiring dedicated fan clearance.
The electrically released brake supplies 70 Nm of static holding torque, allowing vertical axes to remain fixed when the inverter is de-energized. A plain shaft transmits torque through clamp or collet couplings and helps minimize backlash at reversal points. The housing achieves the IP65 protection rating, blocking dust and water jets encountered in washdown workcells. Operation is specified between 0–40 °C, matching typical control-cabinet climates in factory settings. This sealing level suits enclosed machine areas where dust or cleaning spray may be present.
