Product Description:
The MSK076C-0300-NN-S2-UG1-RNNN is a servo motor built by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. As a compact drive element, it supplies closed-loop position and velocity control for automated machinery, packaging equipment, and pick-and-place stations where quick response and consistent torque are required. The motor is intended for use with a compatible servo drive so commanded current can be translated into accurate rotary motion during repeated start-stop cycles. Its synchronous design supports responsive acceleration and steady low-speed control when the drive is tuned for the axis mechanics. An increased concentricity design helps minimize shaft runout, which supports smoother motion at the load and more consistent coupling behavior.
Heat is removed through natural convection, so no external blower or liquid circuit is needed. The enclosure has an IP65 rating that helps keep dust and water jets away from internal parts. The feedback system uses a rotatable 240° connector and an EnDat 2.1 interface, and the encoder provides 2048 signal periods of incremental data for precise interpolation by the connected drive. Safe operation is permitted from 0 to 40 °C, which fits common machine and cabinet environments. Basic mechanical data include motor size 076, length code C, a plain shaft for coupler or pulley mounting, and winding code 0300 for the matching controller setup. The plain shaft allows direct coupling with pulleys or clamping hubs where keyed transmission is not required.
An electrically released holding brake supplies 11 Nm of static torque, allowing vertical axes to remain stationary when power is removed. The feedback system is single-turn, so position is tracked within one mechanical revolution and startup logic can remain straightforward on many axis designs. Encoder technology is optical, providing high signal quality and resistance to magnetic interference, while the rotatable plug eases cable routing where space around the motor is limited. The motor uses thermal class 155, and the insulation system supports continuous winding temperatures up to 311 °F when operating within the permitted limits. That thermal margin helps the windings handle repeated load changes during cyclic motion.
