Product Description:

The MSK100C-0450-NN-M2-RP0-RNNN servomotor is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is a synchronous servomotor that converts drive current into controlled torque for positioning and speed regulation on packaging lines and gantry axes. Used with compatible Rexroth drive amplifiers, it supports fast position-loop response for repeatable motion in automated equipment. This motor format is well suited to applications that need accurate starts, stops, and speed changes without adding external motion hardware at the axis.

This C-length, size 100 rotor-stator assembly relies on natural convection to remove heat, so auxiliary fans or liquid loops are not needed. Winding code 0450 is used for a medium-torque operating profile, while an increased concentricity design helps reduce radial runout that can add stress to the bearing system during continuous motion. Axis position is measured by an EnDat2.1 optical encoder that produces 2048 signal periods per mechanical turn. Because the feedback system uses multiturn absolute measurement, the controller can retain shaft position information after a power cycle and resume axis reference data without incremental recounting. The motor is supplied without a holding brake, which allows free back-driving when the inverter is disabled. Its housing carries an IP65 rating that helps protect internal components from dust and low-pressure water exposure in typical industrial areas.

Installation uses a right-side power connector, which helps route high-current cabling away from the feedback connection and can simplify cable paths in compact machine layouts. The output uses a shaft with keyway for positive mechanical engagement with pulleys, couplings, or similar driven components. Continuous operation is permitted within an ambient range of 0–40 °C, which fits common enclosed machine spaces with controlled airflow. Inside that temperature range, the class-F winding insulation is rated to 155, supporting thermal durability during extended production cycles. The passive cooling arrangement also reduces maintenance points because there are no separate blower assemblies or liquid cooling circuits to service.
