Product Description:

The MSK101E-0300-FN-S1-AG2-NNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for precision positioning in automated machinery. It belongs to the MSK IndraDyn S Synchronous Motors series and combines the 101 frame size with the E length to provide higher continuous torque in a compact form. In servo axes, it converts commanded current into controlled rotary motion for positioning, indexing, and speed-regulated movement. A plain shaft eases coupling to gearboxes or other driven components, and the standard mechanical design supports installation in tightly arranged machine assemblies.

The motor uses liquid cooling, indicated by the FN attribute, so coolant circulates around the stator to remove heat during continuous duty. This cooling method reduces reliance on ambient airflow around the housing and supports stable thermal operation under sustained load. Position feedback is carried through the Hiperface interface, and the optical sensor provides 128 signal periods per revolution for precise closed-loop control. The housing has an IP65 rating, which helps keep out dust and low-pressure water jets even when external coolant lines are connected. An electrically released brake supplies 70 Nm of holding torque when power is removed, securing the shaft at standstill.

The encoder is single-turn, so it reports absolute position within one mechanical revolution and the control system must track additional turns separately. This feedback format suits axes where the drive or controller already monitors travel over multiple revolutions. Safe operation is permitted in ambient temperatures from 0–40 °C, and the windings use class 155 insulation for elevated internal temperatures. The A-side connector places power and coolant connections on one face of the motor, which can simplify routing in compact installations. Grouping these connections on one side also helps keep hose and cable paths organized around the machine frame.
