Product Description:

The MSK071D-0300-NN-S2-UG1-RNNN is an IndraDyn S synchronous servomotor developed by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor converts electrical power into tightly regulated rotary motion, allowing machine tools, pick-and-place systems, and other automated equipment to follow commanded positions with repeatable accuracy. Its servo design supports precise acceleration and deceleration during frequent start-stop cycles, which helps maintain stable motion on demanding axes. A plain shaft interface simplifies coupling to gearboxes or belt pulleys, and the 071 frame with D length accommodates the 0300 winding code for standard voltage systems.

Heat is dissipated through natural convection, so no external blower or liquid circuit is required. The motor also uses an increased concentricity design that helps keep shaft runout low during continuous duty. Position feedback is handled through a rotatable 240° connector and an EnDat2.1 optical encoder. That encoder provides 2048 signal periods per revolution, giving the drive high-resolution data for commutation and velocity loops. A factory-installed, electrically released brake supplies 23 Nm of static holding torque to secure vertical loads when the drive is de-energized. The motor is sealed to IP65, which helps protect internal components from dust and low-pressure water jets during washdown operation.

Continuous operation is permitted in ambient temperatures from 0 to 40 °C, which suits most cabinet-based machine layouts. The encoder’s optical principle, combined with its single-turn format, reports the absolute rotor angle within one revolution without mechanical wear in the sensing system. Thermal endurance corresponds to insulation class 155, so the winding system can withstand elevated internal temperatures before degradation. This combination of encoder feedback, brake holding capability, and thermal capacity makes the motor suitable for precise positioning tasks under sustained industrial use.
