Product Description:
The MSK061C-0300-NN-S2-UP0-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It provides precise torque and speed control for automated axes, allowing numerical controllers to position loads with the accuracy required in packaging equipment, pick-and-place gantries, and metal-cutting spindles. Its size 061 housing with length C gives it a compact format for machine axes that need a balance of output and installation space. The motor also uses winding code 0300, an increased-concentricity design, and a shaft with a keyway to support accurate coupling alignment and secure torque transfer.
This model relies on natural convection to carry heat away from the stator, so no external fan or coolant circuit is required when the motor is installed in free air. That cooling method reduces the number of auxiliary components around the axis and keeps the layout simple. Position feedback is transmitted through the digital EnDat2.1 interface, giving the drive access to diagnostic data and automatic parameter transfer. The feedback element uses an optical measuring system with 2048 signal periods, which supports smooth commutation and stable low-speed motion. A housing and terminal design rated to IP65 helps keep dust and low-pressure water jets away from the windings in typical industrial environments.
Servo wiring exits through a rotatable 240° connector, so the cable direction can be adjusted after the motor is mounted. This makes it easier to route the cable in tight machine spaces or around nearby mechanical parts. The encoder is a single-turn variant that reports absolute shaft angle within one revolution, which suits short-stroke axes that reference before each cycle. The unit is supplied without a holding brake, so static load retention must be handled by the drive or by external clamps. Continuous service is permitted from 0 to 40 °C, and insulation class 155 supports the motor’s thermal capability in standard cabinet and machine environments.
