Product Description:

The MSK030B-0900-NN-S1-UG0-NNNN servomotor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts drive-controller output into precise rotor motion for positioning axes in packaging, pick-and-place, and printing machinery. Its compact 030 frame and B length fit tight mechanical envelopes while supporting the dynamic torque and speed control expected from closed-loop brushless servo operation. This type of motor is used where the drive must regulate acceleration, speed stability, and stopping position with low delay.

Heat generated by the stator windings is removed through natural convection, so no forced-air or liquid cooling accessories are needed. Feedback is provided by an encoder that combines optical scanning with single-turn absolute position tracking and delivers 128 signal periods per mechanical revolution, giving the drive fine position resolution. Signal exchange takes place over the Hiperface interface, and the encoder connector can be rotated through 240 degrees to route the cable toward the nearest wiring channel. Absolute position information is available immediately after startup, which helps the axis return to controlled motion without a separate reference run. The motor uses a plain shaft for direct coupling, and it is supplied without a holding brake, so an external method is required to hold the load when power is removed.

The mechanical layout follows the standard design code, so mounting dimensions and seals match common MSK templates. Frame length B gives the motor a short axial profile while maintaining the active stack needed for servo duty. Inside the stator, winding code 0900 sets the electrical characteristics expected by the matching drive, including the voltage constant and rated speed range. The selected winding supports electrical matching between the motor and controller so current, back EMF, and speed behavior remain within the intended operating range.
