Product Description:
The MSK100D-0300-NN-S2-AP2-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed for servo axes that demand high positioning accuracy, the unit converts controlled drive output into repeatable mechanical motion in CNC tables, packaging lines, and material-handling gantries. Its electromechanical layout features increased concentricity to minimize radial runout and maintain smooth rotation during precise interpolation tasks. The motor is intended for closed-loop operation with a compatible servo drive, allowing commanded motion to be corrected continuously as load conditions change.
The stator uses winding code 0300, which indicates the resistance and induced voltage characteristics used by this model. Heat produced by copper losses is dissipated through natural convection, so the motor must be mounted where ambient air can circulate freely. This cooling method avoids the need for an external fan and keeps the housing arrangement simple. Position feedback is provided by an optical encoder that communicates via EnDat2.1 and delivers 2048 signal periods per revolution, enabling fine interpolation by the drive controller. Because the encoder is a single-turn device, it reports absolute position only within one mechanical turn. The mechanical housing is length D and matches the 100-frame stator diameter.
An electrically released brake supplies 70 Nm of holding torque, helping keep the axis in place when power is removed. Torque is transmitted through a shaft with keyway, allowing secure coupling to gears, timing belts, or rigid couplings. Power conductors enter on the A-side of the housing, which can simplify cable routing where space is limited near the motor connection area. The encoder uses single-turn topology, which reduces component count and keeps the feedback arrangement straightforward. When multi-turn absolute data are required, the application controller can track revolutions externally while still benefiting from the high resolution and low commutation error of the optical feedback system.
