Product Description:

The MSK070D-0300-NN-M3-UP0-NNNN is an AC servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It operates as a direct-drive actuator in automated assemblies, providing closed-loop torque and speed regulation for tasks such as feeder axes, printing cylinders, or robotic joints. By combining a compact stator, permanent-magnet rotor, and high-resolution feedback, the motor helps reduce transmission components and achieve position repeatability measured in fractions of a degree. Its synchronous design also supports stable low-speed motion and repeatable positioning on axes that cycle frequently.

Cooling relies on natural convection, so the housing surface must remain unobstructed for proper heat transfer during continuous duty. A 240° rotatable encoder connector allows flexible cable routing inside tight enclosures. The embedded encoder communicates through the Hiperface protocol, and its capacitive scanning method tolerates vibration and airborne contaminants better than optical discs. This sensor provides multiturn absolute position information across sixteen signal periods, so the drive can restore shaft angle immediately after power is restored. That behavior is useful on axes that cannot easily return to a reference marker between cycles.

The unit is supplied without a holding brake, so vertical or suspended loads must be secured by external clamping or dynamic motor torque when power is removed. The motor uses a D length stator, which accommodates additional winding turns without increasing frame height. Torsion is transferred through a shaft with keyway, enabling straightforward coupling to pulleys, gearboxes, or synchronous belts. Drive parameters are matched to winding code 0300, giving consistent resistance and inductance values for identical axes in a multi-axis machine.
