Product Description:
The MSK030B-0900-NN-M1-UG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. As a drive component, it converts controlled electrical energy into rotary motion for positioning tables, indexing conveyors, and other closed-loop motion axes in industrial automation. By integrating digital feedback and operating with matched IndraDrive amplifiers, the motor maintains accurate torque and speed regulation during acceleration, steady travel, and short positioning moves. Its standardized mechanical envelope supports integration into compact machine layouts where installation space is limited and predictable mounting geometry is important.
Heat dissipation relies on natural convection, so no external fan or liquid circuit is needed, and mounting clearances must permit free airflow around the housing during continuous operation. The feedback plug is rotatable through 240°, enabling the cable exit to be oriented relative to the machine frame and easing installation in confined spaces. Position data is exchanged over the Hiperface serial interface, which stores motor parameters inside the encoder for automatic recognition by the connected drive. The encoder generates 128 signal periods per mechanical revolution through an optical scanning method, giving adequate resolution for smooth velocity control, stable commutation, and accurate response at low speeds.
Because the sensing element is a multi-turn absolute version, the system reports shaft angle across many turns without a homing cycle after power returns. The motor is supplied without a holding brake, so static load retention must be achieved by external means or by drive torque alone when the axis is stopped. Frame code 030 indicates the motor size, while winding code 0900 sets the voltage constant for use with low-power IndraDrive units. A plain shaft supports direct coupling to gearheads or clamping hubs, and the standard mechanical design does not include a shaft sealing ring.
