Product Description:
The MSK061C-0300-NN-S1-UG0-NSNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. In an automation cell, this motor receives drive current from a Rexroth power module and converts it into rotary motion for indexing tables, feed axes, or ancillary tooling. Its feedback interface lets the controller close position loops directly, so the device works as a compact, high-precision actuator rather than a simple power spindle. It is suited to applications where compact installation space and precise response are both important.
Thermal management relies on natural convection, eliminating external fans and simplifying enclosure layouts. The housing carries an IP65 rating, so dust and low-pressure water jets do not reach the stator laminations. With motor size 061 and the elongated C length, the active stack pairs with winding code 0300 to meet medium-torque requirements on packaging or material-handling axes. The motor is supplied without a holding brake, so holding torque at standstill must be provided by the drive or by external mechanics. Position data is generated by an optical single-turn encoder and exported on the Hiperface bus. Because cooling is passive, no separate fan wiring or service points are added around the motor body.
The feedback connector can be turned through 240° to clear neighboring cables and maintain minimum bend radii inside the cabinet. Inside the measuring head, the grating delivers 128 signal periods per revolution, giving the drive the interpolation depth needed for smooth velocity control. This helps the control loop maintain stable motion at low speed and during small position corrections. A plain shaft with no keyway simplifies coupling to backlash-free clamp hubs, which is common on servo-controlled actuators. Continuous duty is permitted at ambient temperatures from 0 to 40 °C, and thermal insulation class 155 permits internal winding temperatures well above that range without degrading varnish integrity.
