Product Description:

The MSK071D-0300-NN-S1-UP0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. As a servo actuator, it converts the regulated output of a drive controller into precise rotary motion for positioning tasks on packaging lines, gantry axes, and other automated machinery.

Its cooling relies on natural convection, so heat is removed through the housing surface without forced air or liquid circuits; this simplifies cabinet layout and reduces maintenance. The feedback system uses the Hiperface digital protocol, permitting simultaneous power and data transmission between the motor encoder and the drive. Inside the encoder, an optical scanning element produces 128 signal periods per revolution, giving the controller fine position granularity over the full mechanical turn. Because the code disc is singleturn, the absolute position is referenced within one revolution, while multi-turn counting must be handled by the external control logic. Cable routing is flexible thanks to a rotatable 240° connector, allowing the encoder plug to be aligned to available clearance in tight machines.

The rotor follows winding specification Winding Code 0300, meaning its electrical resistance and inductance are matched to MSK drive outputs rated for medium torque in the 071 frame. That frame, labeled Motor Size 071, shares mounting dimensions across the series and pairs with the D-length stator to increase active iron without enlarging the flange. Because the unit ships without a holding brake, designers must use mechanical clamping or the drive’s torque to secure load positions during power-off. Torque is transferred through a shaft with keyway, an arrangement chosen for positive, slip-free coupling to gearboxes or pulleys. The motor keeps a standard housing, so installation practices mirror other MSK models that depend on natural cooling surfaces.
