Product Description:

The MSK050B-0450-NN-S2-UP0-RNNN synchronous servomotor is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It converts controlled output from a compatible drive into precise rotary motion for positioning and speed-regulated axes in assembly, packaging, and material-handling equipment. This motor uses a compact size 050 housing with length code B, so it fits machines that need moderate torque without taking much installation space. Its permanent-magnet synchronous design also supports quick response during repeated starts, stops, and speed changes. That makes it suitable for feed axes, indexing mechanisms, and other servo tasks that require repeatable motion under changing load conditions.

Thermal management relies on natural convection, so the housing releases heat without external fans or liquid cooling hardware. The winding code 0450 is intended for continuous duty within an ambient temperature range of 0 to 40 °C. Sealing reaches IP65, which helps block dust and low-pressure water jets from the stator, connector area, and bearing section. Position feedback is supplied by an EnDat 2.1 optical encoder with 2048 signal periods, giving the drive detailed angle information together with digital communication and stored motor data. This feedback arrangement supports accurate commutation and stable closed-loop control across the motor's operating speed range.

The mechanical layout uses an increased-concentricity design to reduce radial runout where couplings require accurate alignment. This version is useful where belts, pinions, or precision couplings benefit from lower running deviation at the shaft end. The encoder connector is rotatable through 240°, which helps route cables in tight machine spaces without forcing a fixed exit direction. Its optical measuring system is a single-turn device, so it reports absolute position within one motor revolution. Torque is transmitted through a shaft with a keyway, the windings use insulation class 155, and the motor is supplied without a holding brake to keep rear-end mass lower.
