Product Description:

The MSK071D-0300-NN-S3-UG0-NPNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a permanent-magnet AC unit, it converts electrical power from a drive into controlled angular motion for positioning axes, gantry stages, or packaging machinery. The housing and internal feedback elements allow motion controllers to receive precise rotor angle data, which supports stable velocity regulation and accurate torque control during demanding automation cycles. This layout makes the motor suitable for closed-loop servo systems where quick speed corrections and repeatable positioning are required across changing loads.

For heat removal, the stator relies on natural convection, eliminating the need for external cooling circuits. Installation uses B5 flange mounting, so the motor face can be bolted directly to machine frames without additional brackets. Integrated feedback uses a Hiperface digital link that transports position and identification data from the capacitive single-turn sensor, and the connector can be rotated 240° to accommodate cable runs. The measuring system provides 16 signal periods, which supports precise commutation and responsive control. The rotatable connector helps reduce cable strain in compact machine spaces and supports cleaner routing around guards and moving assemblies. The unit is supplied without a holding brake, so a parked load must be secured by the drive or by external mechanics. Electrical characteristics are set by winding code 0300, and the size 071 frame offers a compact cross-section with useful torque capacity.

The motor supports continuous service between 0 to 40 °C, and the sealed housing carries an IP65 rating that blocks dust and low-pressure water jets. Power is transmitted through a plain shaft, which suits clamping couplings and avoids keyway-related stress points. Thermal endurance matches insulation class 155, so the windings can tolerate high operating temperatures within the insulation system limits. The D-length body adds active copper for higher continuous torque without changing the mounting interface. This arrangement is useful in compact machine designs that need consistent output without separate cooling hardware. The motor also maintains reliable operation under vibration levels common in machining centers and high-speed pick-and-place equipment.
