Product Description:

The MSK100B-0450-NN-M1-BP0-NNNN is an AC synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In an industrial automation line, this motor couples to planetary gearboxes, ball screws, or direct-drive couplings to position loads with high dynamic accuracy. When operated with a matched IndraDrive controller, it forms a closed-loop axis that follows speed and position commands with millisecond response. Typical duties include indexing magazine tables, regulating feed rollers, and coordinating multi-axis gantries during packaging, printing, or assembly processes. This operating role allows the motor to handle rapid starts, stops, and repeatable motion changes without sacrificing positioning consistency.

As a standard design unit, the motor uses natural convection rather than forced cooling, so it should be installed with adequate space around the housing for heat dissipation. Position feedback travels through the single-cable Hiperface interface, and an optical sensor reads 128 signal periods per revolution for precise interpolation by the drive. The product type is an IndraDyn S synchronous servomotor, which keeps it compatible with standard drive libraries used for this motor family. Its dimensional classification is motor length B, and the 100 frame size provides the mounting envelope and stack proportions used for this configuration. A keyed shaft supports rigid torque transmission to couplings or driven machine elements.

The encoder supports multiturn absolute position storage for up to 4,096 revolutions, so the drive can retain position information after a power interruption without requiring a new homing cycle. Because the unit is supplied without a holding brake, vertical axes need external locking or drive-generated torque to hold position at standstill. Power and ground conductors exit on the B-side connector, which helps keep cable routing away from moving machine parts and simplifies routing in compact installations. Electromagnetic behavior follows winding set 0450, while frame size 100 provides the torsional stiffness needed for high-bandwidth positioning tasks. This combination suits axes that need accurate feedback, stable torque transmission, and predictable response during repeated motion cycles.
