Product Description:
The MSK040C-0450-NN-M3-UG0-NNNN is a servo motor engineered by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a compact drive element, it converts control commands into precise rotary motion for positioning, packaging, and material-handling axes. It integrates with closed-loop automation systems where fast response and stable velocity regulation are required, and the feedback system allows the connected drive to compare commanded motion with actual shaft position during operation. Its compact format also makes it suitable for installations where mounting space is limited and accurate motion must be maintained over repeated cycles.
Heat is dissipated solely by natural convection, so no external fan or liquid circuit is required when the motor is installed with adequate airflow around the housing. The encoder connector can be rotated through 240 degrees, which helps route cables cleanly in confined machine spaces without placing unnecessary stress on the connection point. Positional data is transmitted through the Hiperface interface, and each mechanical revolution is divided into 16 signal periods by the measuring system. The sensor uses capacitive scanning, which offers stable feedback performance in environments where magnetic fields or light oil mist may be present. A multi-turn absolute feedback design preserves position information over multiple shaft rotations, so the control system can recover axis position after power returns. The enclosure has an IP65 rating that helps protect internal components from dust and low-pressure water jets.
The output side uses a plain shaft for connection to clamp-style or other keyless couplings commonly used in precise drive assemblies. Because the motor is supplied without a holding brake, any need to keep a load fixed at standstill must be handled by the drive or by a separate external mechanism. The C length, 040 frame size, and 0450 winding place this motor in a compact configuration suited to light axis duties where low moving mass is beneficial. Operation is specified within an ambient range of 0 to 40 °C, and the insulation system uses class 155 materials to support continuous thermal loading during cyclic motion.
