Product Description:

The MSK075D-0450-NN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It acts as a drive element for automation axes that need precise position and speed regulation, including pick-and-place gantries, packaging stations, and tool changers. By combining a compact stator with an optical feedback device, the motor supplies repeatable torque and real-time rotor data for closed-loop motion while using little installation space. Its compact form also helps when machine layouts leave limited room around adjacent tooling, guarding, or cable runs.

Thermal behavior relies on natural convection, so no external blower or coolant circuit is required while the unit operates within its 0–40 °C ambient range. A sealed housing rated at IP65 blocks dust and low-pressure water jets that may occur during washdown or airborne coolant exposure. Rotor position is measured in 2048 signal periods by a single-turn optical encoder that communicates with the drive over the EnDat2.1 serial interface, allowing digital feedback and parameter transfer. Frame size 075 and length code D set the mechanical envelope, and winding code 0450 corresponds to the electrical values used by the controller.

Mechanical runout is reduced by an increased concentricity design, which helps improve coupling alignment under dynamic load. The motor is supplied without a holding brake, so static loads must be restrained by external clamps or drive torque. A smooth plain shaft supports connection to precision gear sets, and the feedback connector is rotatable through 240°, which helps with cable routing in restricted panels. Insulation class 155 permits winding temperatures up to 155 °C before thermal degradation. These features support stable operation in repeated motion applications where alignment, feedback quality, and simple cable routing are important.
