Product Description:

The MSK100C-0300-NN-S1-BG2-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It provides closed-loop torque and position control for industrial axes found in packaging lines, metal-cutting equipment, and automated assembly cells. The unit delivers electromechanical power in a ready-to-mount package that can be coupled to a gearbox or ball screw to convert drive current into repeatable linear or rotary motion. This arrangement suits positioning, indexing, and speed-controlled motion tasks where repeatability and compact installation are important.

Thermal management is handled through natural convection, so heat is released to the surrounding air without a fan or liquid circuit. Rotor position feedback is exchanged over the Hiperface protocol, and the internal optical encoder produces 128 signal periods per electrical revolution. Its single-turn design reports absolute position within one mechanical turn and supports accurate startup feedback. Power enters on the B-side of the housing to separate high-voltage terminals from signal connectors, and winding code 0300 indicates the electrical characteristics expected by a matching IndraDrive controller. The motor uses the standard design for this configuration.

The electrically released holding brake supplies 70 Nm of static torque, allowing the axis to remain fixed during power loss or when the machine is stopped. This helps prevent axis drift on loads that must hold position at standstill. Physical proportions are set by motor length C and frame size 100, creating a mid-range package that balances inertia with peak torque density. A plain shaft is provided so backlash-free clamp couplings or shrink discs can be fitted without keyways. That shaft style also supports friction-based couplings that avoid the play associated with keyed connections.
