Product Description:
The MSK071E-0450-FN-S2-UG2-RNNN belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. It is a synchronous servomotor intended for high-bandwidth speed and position control in industrial automation. When paired with a suitable drive controller, the motor delivers repeatable rotary motion for indexing tables, gantry axes, and other electromechanical loads that require accurate trajectory control. Its design is suited to applications where stable feedback, controlled torque delivery, and compact integration are all important.
This model uses liquid cooling, so an external coolant circuit is required to remove heat from the stator during operation. The increased concentricity design helps maintain a uniform air gap, which reduces cogging during fine interpolation and supports smoother motion at low speed. A rotatable 240° encoder connector improves cable routing where installation space is limited. Feedback is provided through the EnDat2.1 digital interface, and the optical measuring system delivers 2048 signal periods in a single-turn format for absolute position detection within one mechanical revolution. Optical scanning also reduces sensitivity to mechanical wear, while insulation class 155 supports elevated winding temperatures. Winding code 0450 identifies the electrical characteristics expected by compatible IndraDrive amplifiers.
The motor includes an electrically released holding brake with 30 Nm of static torque, so the shaft can be held when supply power is removed. Size 071 with length code E sets the mounting envelope for the machine layout. The output uses a plain shaft, which supports coupling to gearboxes or direct-driven loads. The housing is sealed to IP65, which helps protect internal components from dust and low-pressure water jets. Permissible ambient operating temperature is 0 to 40 °C without derating. A single-turn feedback format and the holding brake make the motor suitable for axes that need accurate positioning together with secure standstill behavior.
