Product Description:

The MSK100B-0400-NN-S3-AP2-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts inverter output into controlled rotary motion for indexing tables, presses, and gantry axes in industrial automation. The motor’s 100 frame and B length give it the mechanical envelope needed for mid-range torque tasks without increasing cabinet depth. Drive feedback and braking functions are integrated, so separate position sensors or external mechanical locks are not required at the machine level.

The winding code is 0400, which indicates the voltage constant used by compatible Rexroth drives. Heat produced by copper losses is removed by natural convection, eliminating the need for forced air or liquid loops in cabinets with limited airflow. An enclosure rating of IP65 seals the stator against dust ingress and low-pressure water jets, permitting installation on open production lines. For load holding, the electrically released brake supplies 70 Nm of static torque, preventing shaft rotation whenever the drive is disabled. Position data travels through the Hiperface interface, enabling feedback communication with compatible control hardware.

Motion accuracy is supported by an encoder resolution of 16 signal periods per revolution, and the single-turn capacitive technology avoids magnetic saturation effects during high-speed operation. Thermal endurance is supported by insulation class 155, allowing continuous winding temperatures up to 155 °C without premature varnish breakdown. The motor operates within an ambient range of 0 to 40 °C, so no derating is needed in standard factory climates. Mechanical power is transmitted through a shaft with a keyway, ensuring positive torque transfer to couplings or pulleys while maintaining alignment under cyclic loads. The A-side power connector simplifies cable routing toward drive cabinets positioned along the same axis.
