Product Description:

The MSK101E-0300-NN-M1-RG2-NNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. In multi-axis machining centers and packaging lines, it converts drive current into precise rotary motion and links electronic motion commands to physical load movement. Its frame 101 and length E place it in the higher-torque portion of the product line, making it suitable for axes that need accurate response under changing load conditions. The motor supports coordinated motion where multiple axes must start, stop, and track commanded profiles together. It is intended for servo applications that demand repeatable speed regulation and accurate positioning during continuous production.

The unit has an IP65 protection rating, so the housing resists dust ingress and low-pressure water jets during machine operation. Cooling is by natural convection, so heat is removed by free airflow instead of a forced fan. An electrically released holding brake provides 70 Nm of static torque to secure vertical or indexing loads when supply power is removed. Position data is transmitted through the Hiperface interface, and the optical encoder generates 128 signal periods per revolution. This feedback arrangement supports smooth commutation, stable low-speed motion, and accurate interpolation by the connected drive.

Thermal insulation class 155 allows winding temperatures suited to intermittent overloads associated with winding code 0300. A plain shaft simplifies coaxial coupling and helps reduce backlash in direct-drive connections. The power circuit is accessed through a right-side connector, which keeps motor and drive cabling on one plane of the panel. This arrangement helps keep cable routing orderly when the motor is mounted near guards or machine frames. Operation is specified for ambient conditions from 0 to 40 °C, and the multi-turn absolute encoder stores position across 4096 revolutions without external batteries. Stored absolute position information reduces the need for reference moves after power interruptions.
