Product Description:

Bosch Rexroth Indramat builds the MSK061B-0300-NN-S1-UG0-NNNN as part of the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servomotor, the unit converts drive current into precisely controlled rotary motion for positioning, contouring, or speed-regulated tasks in automated machinery. The motor’s electrical and mechanical interfaces align with IndraDrive amplifiers, so it can be integrated directly into packaging machines, pick-and-place portals, or material-handling axes that require accurate torque delivery and coordinated feedback during repeated motion cycles.

The motor releases heat through natural convection, eliminating fans and supporting a simpler installation layout around the housing. An ingress protection rating of IP65 seals the stator housing against dust and low-pressure water, which allows installation outside control cabinets when the application permits. Feedback travels over a Hiperface connection, and this digital link works with a rotatable 240° encoder plug that helps with cable routing in tight spaces. Inside the housing, an optical sensor resolves rotor position into 128 signal periods, which supports high interpolation in the drive. A plain shaft interface accepts clamp couplings or shrink discs without keyways, helping maintain low runout. The standard mechanical design, size 061, and length code B set the outer diameter and stack height for compact axis layouts.

Permitted ambient operation spans 0 to 40 °C, so the motor can run in standard factory spaces without derating. Insulation class 155 supports winding temperatures typical of cyclic servo duty while maintaining dielectric safety during normal operation. The encoder works in single-turn mode, so it reports absolute position within one revolution and suits short-stroke axes that return to a known reference through software. Because the unit is delivered without a holding brake, stationary retention during power-off must be provided by external clamps or a gravity-balanced mechanism. Winding code 0300 indicates the coil configuration used to balance torque output with acceptable current demand for this motor size.
