Product Description:

The MSK101C-0450-NN-S1-AG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S motor, it converts power from a compatible inverter into precise rotary motion for positioning axes, pick-and-place heads, and general machine tool functions. Its sealed housing supports direct installation on production equipment without an auxiliary enclosure. The integrated encoder allows closed-loop control for accurate torque, speed, and position regulation. This arrangement suits indexing tables, transfer systems, and other automated stations that require repeatable motion.

The motor uses natural convection for heat removal, so the housing dissipates losses without fans or liquid circuits. A protection rating of IP65 keeps out dust and resists water jets, which supports use near coolant spray or airborne particles. Position feedback is transferred through the Hiperface interface, combining sine-cosine analog tracks with a digital channel so the drive can read absolute data at startup. Inside the encoder, an optical disc provides 128 signal periods, and the controller interpolates that signal for fine angular resolution during motion. This feedback arrangement gives the controller the rotor position needed for commutation and stable speed regulation across the operating range. The motor is supplied without a holding brake, so the load must be secured by external mechanics or drive torque when power is removed.

The frame size is 101, and the motor has a medium C length that suits mid-range gantry, press, and handling axes. The medium housing length provides additional active material in the same general frame class, which supports solid continuous performance without moving to a larger motor body. A plain shaft supports couplings that use shrink disks or similar clamping elements, and the A-side power connector keeps power and feedback connections on the same end for simpler cable routing. Continuous operation is permitted at ambient temperatures from 0–40 °C, so the motor should be used within that range during normal duty. The winding insulation is rated to thermal class 155, which supports stable operation under the stated ambient conditions.
