Product Description:

The MSK101D-0300-FN-M1-BG0-NNAN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. The device converts commanded electrical current into tightly regulated shaft rotation, delivering the torque, velocity, and position precision required for closed-loop industrial automation. Its reduced runout design limits radial deviation for applications that need accurate concentricity. This makes the motor suitable for positioning axes, indexing units, and other machines that depend on smooth, repeatable motion.

Thermal management relies on liquid cooling, so coolant channels integrated in the stator remove heat and sustain nominal output even in sealed cabinets. Motion feedback is generated by an optical encoder that delivers 128 signal periods per revolution, producing fine interpolation for the drive controller. Communication with the controller uses the Hiperface interface, which carries both position data and electronic data over a single hybrid cable. Because the encoder is multi-turn absolute, the exact shaft angle over thousands of revolutions is retained after a power cycle, eliminating homing routines. A power connector mounted on the B-side separates the power cabling from the feedback lead, and the plain shaft provides a cylindrical surface for clamp couplings without a keyway. Separate power and feedback paths also help keep cable routing organized around the motor housing.

The motor is delivered without a holding brake, so static load retention must be handled externally or by continuous drive torque. Its elongated stator corresponds to length code D, increasing active copper volume inside the frame. Frame size 101 gives a larger bearing span and flange geometry suitable for higher radial forces. Winding code 0300 provides electrical values matched to medium-voltage drive stages. The absence of internal brake components helps lower rotor inertia, and the extended copper length supports higher continuous torque without increasing frame diameter.
