Product Description:

The MSK100B-0300-NN-S2-BG1-RNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop motion control, the unit supplies precise rotary power to transfer lines, gantry systems, and metal-cutting spindles. By combining permanent-magnet excitation with a high-resolution feedback encoder, the motor delivers rapid acceleration, repeatable positioning, and efficient torque generation for demanding industrial automation tasks. It is intended for servo axes that must respond quickly to changing commands while maintaining stable motion over repeated production cycles. In packaging, handling, and machining equipment, this helps the controlled axis hold speed and position as load conditions change during operation.

Heat generated in continuous service is dissipated by natural convection, eliminating the need for external fans and simplifying machine layout. The housing carries an IP65 rating, so dust ingress and low-pressure water jets do not interfere with operation in typical industrial environments. Position data come from an optical encoder with 2048 signal periods per revolution that communicates through the EnDat2.1 interface, and its single-turn format provides absolute position within one mechanical turn. The encoder also gives the drive the rotor angle needed for commutation, so startup and low-speed control remain accurate. A holding brake provides 32 Nm of static torque to secure vertical loads when power is removed, while the plain shaft and B-side connector support clean mechanical integration and straightforward cable routing.

For the basic frame data, motor size 100 identifies the geometry of this unit, and winding code 0300 corresponds to electrical values suited to standard drive outputs. Class 155 insulation supports elevated winding temperatures, and reliable operation is specified for ambient air from 0 to 40 °C. The B-length housing places the motor in a medium-frame format that suits many servo axes without forcing the footprint of a larger machine section. The stated ambient range supports indoor production areas where surrounding heat is controlled and direct external cooling hardware is not required. The motor can be used in continuous industrial service when paired with a compatible drive and installed with adequate free space around the housing.
