Product Description:

The MSK101E-0300-NN-M1-BG3-NNNN is a servo motor built by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. As a rotary actuator, it converts drive current from an IndraDrive controller into mechanical torque for positioning or speed-regulated axes in automated machinery and packaging lines. The model belongs to the synchronous servomotor range and provides precise angle feedback through an integrated encoder for closed-loop motion control.

Thermal regulation relies on natural convection, so the housing dissipates losses without external fans or liquid circuits. The stator uses winding code 0300, which matches the torque constant to medium-voltage IndraDrive inverters. An electrically released brake rated at 120 Nm holds the load motionless during power-off and supports vertical-axis holding. Position feedback comes from an optical encoder with 128 signal periods per mechanical turn, and the data are transmitted over the Hiperface serial interface.

At installation, cable routing is simplified because the power connector is on the B-side, which helps keep motor leads clear of moving machine elements. The output interface uses a plain shaft, allowing shrink-fit or clamp couplings without added runout from a keyed connection. Internal counting electronics provide multi-turn absolute position information, so the drive can report position after power cycling without a homing run. The motor uses frame size 101, and length category E provides higher torque than shorter MSK bodies while staying within a compact installation envelope.
