Product Description:

The MSK071D-0450-NN-M2-UG2-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. It supplies precise rotary motion to automated machinery, allowing closed-loop speed and position control in packaging lines, material-handling axes, and general motion platforms within industrial automation. Its servo design supports fast response to changing command values, which helps the axis maintain smooth movement during repeated starts, stops, and reversals. In coordinated motion systems, the motor works with a matching drive to correct torque output as load conditions change and to keep positioning behavior stable throughout the cycle.

Heat from the stator is removed through natural convection, so the motor can be mounted where forced-air channels are not available while still maintaining its thermal limits. The feedback system uses an EnDat2.1 digital interface and an optical disk that delivers 2048 signal periods, giving the drive a high base resolution for accurate speed and position control. Because the encoder has multiturn absolute capability, the controller receives the actual shaft position and revolution count immediately after power-up. That feedback arrangement allows the axis to initialize without requiring a new reference move after every restart. An electrically released brake provides 30 Nm of static holding torque, allowing the axis to remain still during power loss or emergency stops. The 240° rotatable connector helps route cables away from surrounding machine parts, and the increased concentricity design helps reduce radial runout at the coupling.

The housing carries an IP65 rating that helps prevent dust ingress and water-jet intrusion, so the motor can be installed on exposed machine frames. Continuous duty is allowed in ambient temperatures from 0 to 40 °C, which matches common factory conditions without requiring derating. The output uses a plain shaft for direct connection to backlash-free clamp couplings, and the windings use thermal class 155 to support elevated internal temperatures during operation. This shaft style is suitable for installations that rely on friction-locking couplings rather than keyed hubs, helping preserve alignment in precision motion systems. The sealed housing and keyless shaft arrangement also suit machine sections where clean exterior surfaces and compact coupling layouts are preferred.
