Product Description:
The MSK040B-0450-NN-M1-UG0-NSNN is a synchronous servo motor built by Bosch Rexroth Indramat and placed within the MSK IndraDyn S Synchronous Motors series. As an electrically commutated AC unit, it converts drive-stage current into regulated mechanical torque for positioning axes and feed drives in automated machinery. Size 040 mechanical framing and length code B keep the motor compact. Its compact form suits machine layouts that need precise motion without using much installation space. It is well suited to packaging equipment, handling systems, and compact feed axes that rely on repeatable start-stop motion.
Heat is removed only through natural convection, so mounting space must allow unobstructed airflow around the housing. The enclosure has an IP65 rating, which helps keep out dust and protects against low-pressure water jets. Rotor angle is reported by an optical encoder that communicates over the Hiperface digital link, and its code disk provides 128 signal periods per revolution for incremental feedback to the drive. Multiturn capability comes from a battery-free gear stage, giving the feedback multiturn absolute position retention after power is removed. Operation is permitted in ambient temperatures from 0 to 40 °C, and the motor is supplied without a holding brake. This makes it appropriate for axes where the load can be held by drive torque or by an external mechanical device.
The electrical system uses winding code 0450, which matches nominal voltage and current requirements used by compatible IndraDrive controllers. Insulation class 155 allows elevated winding temperatures before insulation aging accelerates under continuous load. The rotor ends in a hardened steel plain shaft, which supports coupling to backlash-free clamp hubs or suitable gearboxes. This shaft style is appropriate where friction-based shaft connections are preferred over keyed interfaces. With closed-loop feedback and a compact housing, the motor supports accurate speed and position control during normal industrial operation.
