Product Description:

The MSK101D-0300-FN-S1-BG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion tasks in industrial automation, where it delivers repeatable torque and speed to machine axes, pick-and-place stations, or forming presses. By combining a compact frame with integrated feedback, the motor serves as the electromechanical element of a drive chain when paired with compatible drive electronics and power cables. This arrangement allows the controller to regulate acceleration, velocity, and positioning with stable response during cyclic machine operation.

The motor uses liquid cooling, so coolant channels inside the stator carry heat to an external circuit and allow higher continuous power density than air-cooled models. The motor has a frame size of 101, which identifies the stator diameter and mounting hole pattern used in the MSK family. Winding code 0300 indicates the copper fill, resistance, and inductance values used by the matching drive for current settings. Position feedback is handled through a Hiperface interface, and the optical sensor delivers 128 signal periods per mechanical revolution. This feedback supports smooth interpolation, stable low-speed control, and accurate position tracking across changing load conditions.

A plain shaft transmits torque without keyways, simplifying coupling to backlash-free clamping hubs. The encoder is the single-turn type, so the control system reads absolute position within one revolution and relies on the machine control for additional travel reference when needed. For safety stops, the motor is supplied without a holding brake, which reduces mass and eliminates residual drag when free rotation is required. Power is routed on the B-side of the housing, and the standard motor length D helps keep the overall depth within common enclosure dimensions. This layout can help organize cable runs in installations where space around the motor is limited.
