Product Description:

The MSK071D-0450-NN-S1-UG0-NSNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This compact rotary unit converts drive commands into controlled mechanical motion for positioning axes, pick-and-place heads, and packaging machinery. By combining precise feedback with a responsive winding layout, the motor provides stable torque and speed control for automated production lines.

It is cooled by natural convection, so heat dissipates through the housing without external fans or liquid circuits. The design is rated for standard installations and for equipment requiring explosion protection, so it can be used in multiple plant zones. A rotatable 240° encoder connector lets the plug be positioned more easily in cramped cabinets, while the feedback link uses the Hiperface protocol to transmit position data and electronic nameplate information to the drive controller. Inside the encoder, an optical sensor scans a disk that produces 128 signal periods per mechanical revolution, giving the control loop fine angular resolution. The motor is supplied with a plain shaft that mates directly to backlash-free clamps, which helps reduce mechanical compliance in precision axes.

The feedback element tracks only one mechanical turn and is classified as single-turn, which suits applications where multi-turn information is not required. The motor has a frame size of 071 and a motor length of D, giving it a compact footprint while supporting the torque capacity expected from this housing size. Electrical characteristics depend on winding code 0450, which matches the motor to compatible IndraDrive amplifiers for proper current utilization. Because the unit is delivered without a holding brake, external locking devices are required when power-off shaft retention is needed.
