Product Description:

The MSK070D-0450-NN-S1-BP0-NNAN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts drive power from a compatible inverter into controlled motion for indexing tables, pick-and-place axes, and other closed-loop stations on automated lines. The unit is shipped without a holding brake, so position holding during power-off conditions must be provided by external mechanical locking or active torque from the drive controller. This arrangement is common on fast-cycling axes where reduced mechanical complexity and lower rotating mass are preferred.

Cooling is achieved through natural convection, so waste heat is released directly to the housing without fans or liquid loops. The rotor machining follows the Reduced Run-Out standard, limiting eccentricity for smoother bearing operation and accurate coupling. Position feedback travels through a Hiperface link to the drive unit, and the integrated encoder resolves motion into 128 signal periods per revolution by means of an optical scanning track. This single-turn sensor supplies an absolute angle within one turn, which helps the control system establish rotor position quickly after startup. With a protection rating of IP65, the motor resists dust ingress and low-pressure water jets in industrial service. Output torque is delivered by a shaft with keyway that accepts standard couplings. Class 155 insulation keeps the stator windings within temperature limits during repeated duty cycles and frequent acceleration changes.

The housing dimensions correspond to motor size 070 and length class D, giving the motor a compact envelope while leaving room for the winding stack labeled 0450. Continuous duty is permitted when the surrounding air remains within 0–40 °C, and higher ambient temperatures require current reduction to limit copper temperature rise. The low rotor inertia associated with this frame supports rapid acceleration profiles in delta robots and high-speed gantries. These characteristics make the motor well suited to applications that need fast response, precise positioning, and stable closed-loop operation over repeated motion cycles.
