Product Description:

The MSK071D-0300-NN-M2-UP0-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for industrial automation tasks that require precise rotary positioning, including packaging axes, material-handling gantries, and indexing tables. By producing tightly regulated torque from a compact frame, the motor supports accurate motion control without taking up excessive installation space. This makes it a compact option for axes that must respond quickly to changing command signals.

From a mechanical standpoint, the motor has size 071 and length code D, so it fits mid-range machine layouts that use this frame envelope. The internal winding code 0300 sets the electrical characteristics used by the matching drive for this motor size. Heat from the stator is removed by natural convection, which eliminates the need for external fans or liquid-cooling lines. A shaft with keyway provides positive torque transfer to couplings or pulleys. The feedback connection is rotatable through 240°, which allows the connector position to be adjusted for cleaner cable routing and lower strain on the conductors.

Position feedback is provided by an optical encoder with multi-turn absolute capability, so the drive can read shaft position immediately after power is restored. The encoder supplies 2048 signal periods per revolution, and communication is handled through the EnDat2.1 interface for reliable digital data transfer. The housing is built with increased concentricity, which helps reduce radial runout during operation and supports stable feedback quality at higher speeds. Because the motor is supplied without a holding brake, the axis must rely on drive torque or a separate mechanical device to hold position when power is removed. This arrangement is suitable for systems where stopping force is provided elsewhere in the machine.
