Product Description:

The MSK100C-0450-NN-S2-AG2-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servomotor, it converts regulated three-phase power into controlled rotary motion for tooling, conveyors, or robotic joints in automated equipment. The motor works with compatible servo drives to support accurate speed, torque, and position control during repeated indexing and contouring tasks. Its synchronous design helps the rotor stay aligned with the commanded electrical angle, which improves response during load changes and frequent direction reversals.

This unit uses a 100 housing, and its winding code is 0450, which matches the electrical characteristics expected by the drive. The motor has length C, which provides the axial space used by this configuration. Heat is removed through natural convection, so no external blower or liquid cooling circuit is required. The shaft uses an increased-concentricity design to reduce radial runout, and the plain shaft end supports direct coupling to precision gearboxes or pulleys. An electrically released holding brake delivers 70 Nm of static torque to hold the axis when supply power is removed, which is useful on vertical axes and indexing stations.

Position feedback is provided by a single-turn optical encoder using EnDat2.1 with 2048 signal periods per revolution, giving the drive precise commutation and position data. The housing and connectors are rated IP65, which helps keep dust and sprayed liquids away from internal components during normal industrial operation. Insulation class 155 supports continuous operation within the permitted ambient range, and the power connector is placed on the A-side to support straightforward cable routing. Single-turn feedback reports the shaft angle within one mechanical revolution, so position beyond one turn must be tracked by the drive or control system.
