Product Description:

The MSK100C-0300-NN-S1-BP2-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. The unit is classified as a servomotor intended to deliver precise torque and velocity control on packaging lines, material-handling gantries, and similar industrial automation axes. By combining a permanent-magnet rotor with high-resolution feedback, the motor supports closed-loop positioning during indexing, speed regulation, and repeatable start-stop motion. Its keyed shaft also allows straightforward torque transfer to gearboxes, pulleys, and other driven machine elements.

The motor relies on natural convection for heat dissipation, so surrounding airflow must be sufficient to keep surface temperature within permitted limits. Position feedback is supplied through a Hiperface optical encoder that provides 128 signal periods per revolution, giving the connected drive a stable basis for interpolation and commutation. Because the encoder is single-turn, absolute position information is retained over one mechanical turn, which is well suited to axes with limited travel or known restart positions. The motor uses winding code 0300, which matches its torque constant and rated current to compatible IndraDrive power stages. Optical sensing also helps maintain steady phase alignment during rapid acceleration and deceleration.

The installed holding brake is an electrically released unit rated at 70 Nm, allowing the motor to support static loads when power is removed. The housing uses length C in frame size 100, giving the motor a larger installation depth than shorter versions in the same platform. Power is connected on the B-side, while the feedback connection is placed on the opposite face to help separate motor power conductors from encoder wiring. This layout can reduce cable congestion around the motor and supports clean routing in compact machine assemblies.
