Product Description:

The MSK071E-0300-NN-M2-UP0-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a permanent-magnet, electronically commutated unit, it converts drive controller current into tightly regulated torque and angular velocity. The motor is used in pick-and-place modules, printing cylinders, and other precision stations where repeatable motion and high dynamic response are essential for consistent product quality, and its compact frame helps simplify installation in multi-axis assemblies.

Heat generated by the stator is removed through natural convection, so ambient airflow around the motor governs the continuous duty rating. Position feedback is transferred through the EnDat2.1 serial interface, which carries incremental counts, absolute angle data, and diagnostic information between the motor and drive. The internal scanning system subdivides one mechanical revolution into 2048 signal periods, giving high interpolation potential for accurate positioning. Because the transducer is a multiturn absolute encoder, it records revolutions across its available range and retains position information when power is lost, which reduces the need for homing after startup. Cable routing is aided by an encoder connector that is rotatable through 240°, allowing the plug to be set to a more convenient exit angle after the housing is mounted.

Mounting dimensions correspond to frame size 071, while stack length code E extends the magnetic core to support the intended torque output. The output end uses a shaft with a keyway, providing a positive drive interface for pulleys, gears, or rigid couplings and helping prevent slip under peak load. The rotor and stator are machined to an increased concentricity tolerance, which reduces radial runout and supports smooth operation at elevated servo gains. The motor is supplied without a holding brake, so static holding must be provided by external clamping or drive-applied torque. The selected winding data aligns the motor with compatible IndraDrive controllers for effective current use.
