Product Description:

The MSK071C-0200-NN-M3-UG0-NNNN belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. As an IndraDyn S synchronous servomotor, it converts electrical energy into controlled torque and speed for positioning axes, pick-and-place heads, and other automated machinery. The C-length, size 071 frame offers a compromise between footprint and torque density, while its standard mechanical design simplifies mounting to common Indramat drive flanges and couplings in modular production lines.

Heat is removed by natural convection, eliminating blower noise and filter upkeep. For feedback wiring, the motor uses a rotatable 240° encoder connector, allowing the plug to be turned clear of neighboring hardware to reduce cable stress. Inside the housing, position data travel on the Hiperface interface; this bidirectional protocol carries absolute values and memory parameters over two shielded pairs to the drive. Fine incremental data start with a base resolution of 16 signal periods, which the drive interpolates for high-gain control loops. Measurement stability comes from the encoder’s capacitive scanning principle, which is unaffected by magnetic oil mist and keeps accuracy consistent across temperature shifts.

The motor uses the 0200 winding, matching current and back EMF to medium-voltage controllers used on assembly-line axes. The feedback assembly delivers a multiturn absolute position, so the drive restores axis location after power reconnection without external homing. Because the unit is supplied without a holding brake, external holding must be provided by drive torque or a mechanical clamp when static load security is required. A plain shaft exits the front bearing to suit shrink discs or servo couplings and avoids keyway stress points.
