Product Description:

The MSK100B-0400-NN-M1-RG0-NNNN servomotor is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop positioning tasks in automated assembly cells, palletizers, and material-handling stations, the unit converts drive inverter output into controllable rotational motion with high dynamic accuracy. It delivers repeatable torque and speed so that connected machinery follows programmed motion profiles with precise response during frequent starts, stops, and speed changes. In systems that rely on synchronized axis movement, this type of motor is commonly paired with a servo drive that continuously corrects current and speed to maintain the commanded position under changing load.

Thermal management is handled via natural convection, meaning heat moves from the housing to the surrounding air without forced airflow. The motor housing carries a protection rating of IP65, so internal windings stay sealed against dust intrusion and low-pressure water jets on the factory floor. Feedback is provided through a Hiperface interface connected to the integrated encoder, which supports closed-loop control without a separate external sensing package. That encoder uses an optical scanning system and delivers 128 signal periods per revolution, giving the control loop fine incremental information for smooth velocity regulation. Because the encoder data is read directly by the drive, the motor supports accurate commutation and stable low-speed operation during indexing or other precision motion. Multiturn absolute tracking preserves shaft position through power cycles, which helps the drive recover axis position immediately after startup.

The motor uses winding code 0400, which matches IndraDrive current ratings for this size and length. A plain shaft exits the front flange, allowing backlash-free coupling to gears or pulleys, while the power connector is fixed on the right side to simplify cable routing in multi-axis frames. This layout leaves the front end unobstructed for couplings and similar transmission components. Continuous service is supported in ambient temperatures from 0 to 40 °C, and the Class 155 insulation system allows the windings to operate at elevated internal temperatures without premature aging. The motor is supplied without a holding brake, so the axis must be secured by external hardware or drive-controlled torque when power is removed.
