Product Description:

The MSK100C-0300-NN-S2-AG2-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is used on precision positioning axes where closed-loop control requires low mechanical runout, and the motor uses increased concentricity for that purpose. This supports accurate rotary motion in handling units, machine tools, and other automated equipment that depend on stable position feedback. Size 100 stator laminations and the C-length frame provide the torque range expected for medium-power tasks while keeping the unit compact enough for multi-axis assemblies.

Thermal regulation is handled through natural convection, so the housing must be mounted where airflow is unobstructed. Feedback is delivered through an EnDat 2.1 interface that carries position data from an optical sensing system. The encoder provides 2048 signal periods per revolution in a single-turn configuration, which suits axes that return to a reference position at startup rather than storing position through multiple revolutions. Winding code 0300 sets the electrical characteristics expected by compatible Rexroth drives and helps the motor operate within the intended current and voltage range. The A-side power connector supports direct cable routing from the drive cabinet.

An electrically released brake supplies 70 Nm of holding torque so vertical or overhung loads remain fixed during power loss. Environmental sealing is rated IP65, which helps protect the internal windings from dust and low-pressure water jets on production floors. Continuous service is permitted in ambient temperatures from 0 to 40 °C, so the motor can operate in typical indoor production areas without added cooling equipment. The plain shaft supports alignment with clamp or shrink-fit couplings and allows direct torque transfer without a keyed connection.
