Product Description:

Bosch Rexroth Indramat manufactures the MSK100B-0300-NN-S1-AG1-NNNN as part of the MSK IndraDyn S Synchronous Motors series. This IndraDyn S synchronous servomotor converts electrical energy into regulated rotary motion for positioning, feed, and indexing duties in industrial automation lines. With integrated feedback and an internal holding brake, the motor is ready for direct coupling to geared stages or belt drives where dynamic accuracy and a compact form are important. It is intended for servo axes that need controlled acceleration, repeatable stopping, and steady operation through frequent motion cycles.

The unit uses natural convection cooling, so its aluminum housing dissipates heat to the surrounding air without auxiliary fans or liquid circuits. A standard mechanical design keeps dimensions consistent with other MSK motors and supports straightforward installation in established machine layouts. Position feedback is provided through a Hiperface encoder interface, and the drive receives sinusoidal and digital tracks generated by the sensor. The feedback disc is digitized into 128 signal periods, which the drive interpolates for commutation and position evaluation. Because the scanning method is optical, thermal drift and magnetic interference are minimized. The device is further classified as single-turn, meaning the absolute position is valid for one mechanical revolution before the count repeats.

The brake integrated into the end bell is electrically released and supplies 32 Nm of holding torque, preventing unwanted motion on vertical or suspended axes when the drive is disabled. Power is delivered through a connector on the A-side, keeping motor and feedback cabling separate for easier routing. The rotor extends as a plain shaft, providing a clean cylindrical interface for clamp or shrink couplings. Size 100 stator laminations and the B-length stack pair with winding code 0300 for the torque and voltage class used in medium-inertia applications. This arrangement suits machine sections where available space is limited but stable shaft coupling and controlled holding behavior are still required.
