Product Description:
The MSK100A-0450-NN-M1-BG1-NNNN is a servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It serves as a direct-drive actuator in industrial automation, converting electrical energy from an IndraDrive amplifier into controlled torque and speed for positioning tables, gantries, or packaging axes. The unit integrates digital feedback, a holding brake, and sealed construction so it can deliver precise motion without external gear stages or transmission belts. This layout supports applications that need accurate positioning, smooth acceleration, and stable operation across repeated motion cycles.
Heat generated in the stator is removed through natural convection, so the housing relies on ambient airflow rather than forced fans. An enclosure rating of IP65 prevents dust ingress and guards against low-pressure water spray, which supports installation near active process areas. The electrically released brake supplies 32 Nm of static holding torque, allowing vertical axes to remain clamped when power is removed while releasing automatically during motion. Position feedback is transmitted over the Hiperface interface, and the optical scanner resolves 128 signal periods per revolution to support precise commutation and position control. These features help the motor maintain consistent closed-loop response in applications where accurate stopping and controlled restart behavior are required.
The permitted ambient range of 0–40 °C matches the passive cooling concept, so nominal operation is supported in typical factory conditions without auxiliary airflow. A plain shaft is provided for zero-backlash couplings, and the side-mounted connector on the B face helps keep power cabling clear of rotating parts while simplifying routing in compact assemblies. Insulation class 155 supports winding temperatures associated with dynamic duty cycles, and winding code 0450 matches the electrical characteristics expected by the drive. This combination suits installations that need a compact servo motor with sealed housing, integrated feedback, and secure holding capability at standstill.
