Product Description:

The MSK100B-0200-NN-M2-BG1-RNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It serves as a torque and position actuator that links directly to Rexroth drive amplifiers, moving packaging axes, gantries, and handling modules with closed-loop accuracy. The motor combines electronic commutation with high-resolution feedback so that controllers can command smooth speed profiles, precise indexing, and rapid accelerations. By supplying direct shaft power, it can eliminate belt or screw transmissions in many installations and reduce maintenance needs.

Thermal control relies on natural convection; heat exits through the aluminum housing, so no blower or liquid circuit is required. The enclosure carries an IP65 rating that blocks dust and low-pressure water jets, allowing cabinet-free mounting near the load. Position data is passed through the EnDat2.1 interface, and each mechanical turn is digitized into 2048 signal periods by an optical scale for fine interpolation. An electrically released brake supplies 32 Nm of holding torque, keeping the axis fixed during power loss or emergency stops. A plain steel shaft delivers torque directly into couplings without keyways, minimizing radial runout and simplifying hub machining.

Mechanical sizing follows the series convention, with motor size 100 and length code B covering medium-duty loads while staying compact. The encoder is a multi-turn absolute device that maintains position over 4096 revolutions without a battery. The motor is intended for ambient temperatures from 0–40 °C, and Class 155 insulation tolerates normal winding heat within that range. A B-side power connector routes the supply cable straight back, and winding code 0200 pairs the motor with common Rexroth inverters. Increased concentricity in the mechanical design restrains vibration and raises servo stiffness.
