Product Description:

The Bosch Rexroth Indramat MSK070E-0450-NN-M2-UP1-RNNN is an IndraDyn S synchronous servo motor in the MSK IndraDyn S Synchronous Motors series. It serves as a rotary actuator in machining centers, pick-and-place gantries, and printing equipment, where it converts drive current into tightly regulated torque and supports high dynamic response through its permanent-magnet rotor. When paired with a compatible IndraDrive controller, the motor supports closed-loop position and velocity control at the axis. This arrangement helps deliver repeatable motion for applications that require accurate starts, stops, and speed changes.

The unit dissipates heat through natural convection, so no external fan is required. Position feedback is supplied by an encoder that communicates over the EnDat2.1 interface, which transfers absolute position data and diagnostic information to the drive in digital form. Internal resolution reaches 2048 signal periods per revolution, supporting fine interpolation for precise positioning tasks. For flexible cable routing, the encoder plug is rotatable through 240°, which helps reduce cable strain in tight mounting spaces. Because the measuring system is multi-turn absolute, the controller can identify shaft angle and revolution count immediately after power-up, so homing is not required after a power interruption.

A mechanically released holding brake provides 23 Nm of torque to secure the shaft during shutdown, and it disengages electrically when motion is commanded. The feedback system relies on optical scanning, which supports low jitter and stable long-term accuracy. Power is transmitted through a shaft with keyway, allowing positive engagement with pulleys or couplings where slip must be avoided. Winding code 0450 indicates the stator’s resistance and inductance values for matching drive current requirements. The 070 frame with E-length housing offers a compact footprint, and increased concentricity helps limit radial runout during operation.
