Product Description:

The MSK071E-0450-FN-S2-UP0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a compact, liquid-cooled rotary actuator, the unit converts drive current from a compatible controller into precise torque and speed for positioning axes, pick-and-place heads, and other automated machinery. It is intended for closed-loop motion tasks where accurate rotary output and steady response are required during repeated machine cycles.

Thermal management relies on liquid cooling, allowing the stator to dissipate heat without relying on external airflow and helping the motor maintain continuous torque density. Motion feedback is provided through an EnDat2.1 interface, and its optical sensor scans 2048 signal periods to deliver high-resolution position data for closed-loop control. The encoder connector can be rotated through 240° to simplify cable routing inside tight cabinets. Operation is permitted between 0 to 40 °C, and the housing carries an IP65 rating that helps protect internal parts from dust and low-pressure water jets. The motor has size 071 with length class E, and winding code 0450 identifies the electrical winding used for this version.

Precision is enhanced by a design that features increased concentricity, which helps reduce radial runout at the shaft journal. Power is delivered through a shaft with keyway, enabling positive torque transmission to gears or couplings without relying on friction alone. The feedback device is configured for single-turn measurement, which is suitable when absolute position only needs to be retained within one revolution. Because the motor is supplied without a holding brake, the application must secure the load mechanically or through drive torque during power loss. Thermal endurance corresponds to insulation class 155, supporting elevated winding temperatures during continuous duty while maintaining electrical insulation integrity.
