Product Description:

The MSK100C-0300-NN-M2-BG0-RNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Intended for industrial automation, the motor supplies closed-loop torque and velocity so that machinery can execute accurate positioning tasks, sustain repeatable cycles, and respond promptly to controller commands. Its electromagnetic construction and integrated feedback allow it to operate as a direct-drive element in assembly cells, material-handling axes, and packaging lines that demand fast acceleration with minimal maintenance.

With a stator frame coded as 100, the motor supplies torque that suits medium-to-large mechanical loads, while the stack length identified by code C increases active copper for longer continuous duty. The winding set labeled 0300 sets the phase resistance and inductance so that compatible Rexroth drives can command current precisely. Position data come from an optical multi-turn encoder that delivers 2048 signal periods per revolution and communicates through the EnDat2.1 interface, enabling very fine resolution without external batteries. Heat leaves the housing by natural convection, and the enclosure is rated IP65, allowing operation in dusty or washdown work zones without additional enclosures. The plain output shaft simplifies coupling, and the unit is supplied without a holding brake to reduce inertial mass.

The rotor and stator are ground to achieve increased concentricity, which keeps radial runout low so the encoder’s fine resolution can be used at high speeds. Electrical safety is supported by an insulation system rated to class 155, and thermal sensors help keep the windings within that limit during continuous service. The housing is specified for use from 0 to 40 °C, matching general-purpose control cabinet climate guidelines. All power conductors exit on the B-side, which helps keep cable routing away from the shaft end and leaves clearance around the feedback connection.
