Product Description:

The Bosch Rexroth Indramat MSK050C-0600-NN-M2-UP1-RNNN is a synchronous servomotor in the MSK IndraDyn S Synchronous Motors series. It installs on precision motion axes and converts regulated inverter current into rotary power for indexing tables, pick-and-place heads, and feed rollers. Direct coupling to the driven shaft reduces mechanical compliance and helps the integrated feedback system maintain high positioning accuracy in repetitive industrial cycles. The motor is well suited to applications that require repeatable acceleration, steady speed control, and accurate stopping at the commanded position.

The motor has size 050 with length code C, and winding code 0600 matches the electrical characteristics used with compatible IndraDrive power stages. A design that emphasizes increased concentricity helps reduce radial runout at the mounting flange, which supports smooth rotation and consistent coupling alignment. Cooling is provided by natural convection, so no separate fan or liquid loop is required. The housing has an IP65 rating that helps keep out dust and water jets during washdown maintenance. A rotatable 240° encoder connector simplifies cable routing, and the optical feedback head communicates through EnDat 2.1. Inside the encoder, an incremental track with 2048 signal periods supports fine digital resolution, and multi-turn absolute feedback preserves position data after power loss.

An electrically released holding brake provides 6 Nm of static torque to secure vertical loads when the servo is de-energized. The brake is intended to hold the axis at rest, while normal dynamic stopping is handled by the drive and motor control loop. The output uses a shaft with keyway, which provides positive torque transmission to couplings or pulleys. Continuous operation is permitted in ambient air from 0–40 °C, which fits typical cabinet-cooled production areas. The motor also uses insulation class 155, allowing winding temperatures up to 155 °C without loss of dielectric strength. This combination supports stable start-stop duty and reliable holding during extended dwell periods.
