Product Description:
The MSK076C-0450-NN-S2-UG0-RNNN synchronous servo motor is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is used as a precision rotary actuator that converts drive current into controlled torque and speed for positioning tables, pick-and-place heads, and packaging machinery axes. By integrating a high-resolution optical encoder and a low-inertia rotor, the motor supports closed-loop control strategies that improve cycle times and repeatability in automated production lines. This arrangement also helps the drive maintain stable torque at low speed and accurate position tracking during frequent starts and stops.
The motor uses natural convection for heat dissipation, so free air paths around the housing are needed to maintain rated performance. Its feedback connector is rotatable through 240°, allowing the cable exit to align with surrounding equipment and reducing strain on the harness. Position data are transmitted over the EnDat2.1 serial interface, which provides digital diagnostics to the drive. The optical scale delivers 2048 signal periods per mechanical revolution, giving fine commutation and stable feedback resolution. A sealed stator housing with an IP65 protection rating blocks dust ingress and water jets, permitting installation on open machine frames without additional guards. That enclosure helps the motor operate reliably near equipment where splash exposure or airborne debris may be present.
The motor has increased concentricity, which helps keep radial runout low and reduces vibration when it is coupled to a plain shaft connection. Lower runout also improves coupling behavior in axes that require smooth rotation during indexing and contour motion. Because the encoder is single-turn, absolute position is retained within one mechanical revolution, and a new reference is needed after multi-turn movement. The rated ambient range is 0–40 °C, matching common industrial operating conditions. Insulation class 155 supports winding temperatures associated with normal servo duty without reducing service life.
Frequently Asked Questions about MSK076C-0450-NN-S2-UG0-RNNN:
