Product Description:

The MSK100D-0350-NN-M2-AG2-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical energy into rotary motion in automated machinery, and its integrated position encoder allows closed-loop control through IndraDrive amplifiers. This arrangement supports accurate repeatable positioning on feed axes, indexing systems, and other motion tasks that require stable torque and responsive speed control. The servo design is intended for machinery that must start, stop, and reverse with consistent positional accuracy.

This model uses frame size 100 with length code D, and its rotor alignment is refined for increased concentricity to reduce runout during gear or pulley coupling. Cooling takes place through natural convection, so no external fan or liquid circuit is required and the motor can be installed without auxiliary cooling hardware. Motion feedback is delivered by an optical encoder that communicates over EnDat2.1. It provides 2048 signal periods per revolution, and the multiturn absolute format lets the drive retain position data across multiple shaft revolutions for startup without a homing cycle. An electrically released holding brake supplies 70 Nm of static torque to secure vertical or indexing loads when the axis is stopped. The cast enclosure is rated IP65, helping keep dust and water jets away from internal components, and the power connector is located on the A-side of the housing.

The motor is supplied with a plain shaft, allowing backlash-free clamp or shrink-disk connections without a keyway. That arrangement supports smooth torque transmission in direct-coupled mechanisms where keyway play is undesirable. It is intended for continuous operation in ambient temperatures from 0–40 °C; outside this range, output may need to be reduced or additional cooling may be required. The windings use class 155 insulation to withstand elevated internal temperatures during sustained operation. Winding code 0350 identifies the electrical winding arrangement used for this model and matches the voltage and current characteristics expected by compatible drives.
