Product Description:

The MSK076C-0300-NN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a brushless AC motor, it provides closed-loop rotary motion for positioning axes in industrial automation, packaging, and material-handling equipment. Its frame size 076 and length code C set the physical envelope, while winding code 0300 identifies the electrical data used with compatible drive controllers. The motor is intended for servo systems that require repeatable motion and stable response under changing load conditions.

The motor dissipates heat through natural convection, so no external fan or liquid circuit is required. A housing sealed to IP65 helps keep out dust and resists low-pressure water jets, allowing installation on machines without additional guarding. Feedback is delivered through the EnDat 2.1 digital interface, which supports precise position reporting and straightforward encoder wiring to the drive. Mechanical output is provided by a plain shaft, a format commonly used with clamp couplings or shrink disks. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, which suits normal factory conditions without extra cooling hardware. This combination is well suited to machine-mounted use where sealed surfaces and simple thermal management are preferred.

The optical encoder produces 2048 signal periods per revolution and uses a single-turn format, so absolute position is available within one mechanical revolution. Electrical connection uses a rotatable 240° connector, making cable routing easier when space around the motor is limited. The motor uses Class 155 insulation, which supports elevated winding temperatures during normal operation. It is supplied without a holding brake, so any parked load must be secured by external mechanics or drive-applied torque. That encoder arrangement helps the drive determine rotor angle immediately after startup and supports consistent motion on indexing axes. The increased concentricity feature helps reduce radial runout during higher-speed motion.
