Product Description:

The MSK101E-0300-FN-M1-BG3-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts commanded electrical energy into regulated rotary motion for machine tools, packaging stations, and handling modules where precise speed and position control are required. In these systems, the motor works with a drive controller to follow dynamic command profiles and maintain accurate feedback. Its synchronous design supports repeatable acceleration and stable speed regulation during demanding motion cycles. It is suited for servo axes that must repeat short motion sequences with controlled torque and fast response. The motor platform is commonly used where coordinated motion depends on closed-loop regulation rather than open-loop speed control.

This model relies on liquid cooling to remove winding heat, allowing continuous torque production without cabinet airflow. The mechanical frame uses motor size 101 with length code E and winding code 0300. An electrically released holding brake provides 120 Nm of static torque to secure vertical or indexing axes when power is removed. Position data is delivered by an optical encoder over the Hiperface interface; the encoder provides 128 signal periods per revolution and stores position data through the Multiturn Absolute function. This feedback arrangement lets the paired drive monitor rotor position through startup, low-speed motion, and repeated direction changes. Power cables connect on the B-side housing face to simplify routing in tight enclosures.

The encoder uses an optical scanning principle for position detection. The housing has an IP65 protection rating, so dust and low-pressure water jets are kept away from internal components. A plain shaft supports direct coupling without a keyway, and it can be paired with clamp couplings or similar friction-locking connections. Safe operation is permitted in ambient temperatures from 0–40 °C. The motor also uses a thermal class 155 insulation system to withstand elevated winding temperatures during normal operation.
