Product Description:

The MSK070D-0450-NN-S1-BG1-NNAN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit converts drive current into rotary motion for automated axes that demand accurate positioning and repeatable speed profiles. It incorporates a plain output shaft for direct coupling to machinery and uses an internal optical feedback system to keep rotor position aligned with the drive control loop in industrial automation. Its synchronous design allows the paired drive to maintain stable torque production during frequent starts, stops, and reversals.

In operation, heat is removed from the stator by natural convection, so surrounding space must allow unobstructed airflow around the motor housing. The housing carries an IP65 rating, and continuous service is permitted across an ambient range of 0–40 °C without derating. Feedback signals are exchanged through the Hiperface interface, while the optical encoder resolves motion into 128 signal periods per revolution; this resolution supports fine velocity regulation and tight positional tolerances. Power is connected through the B-side connector, and the 070 frame with D length suits medium-inertia loads in compact servo axes.

Mechanical holding force is provided by an electrically released brake that delivers 23 Nm of static torque, allowing vertical or suspended axes to stay motionless when the drive is de-energized. Position feedback is limited to a single-turn count, so absolute position reference remains reliable within one mechanical revolution. Thermal endurance uses insulation class 155, supporting elevated winding temperatures during cyclic peaks. The shaft has a Reduced Run-Out design that limits radial error, improving coupling alignment and decreasing vibration in precision transfer, pick-and-place, and indexing stations.
