Product Description:

The MSK070D-0450-NN-M1-UG0-NNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and speed control in packaging, printing, and material-handling machinery. The motor converts electrical energy into controlled rotary motion for axes that require repeatable movement, stable speed regulation, and accurate response during frequent start-stop cycles. Its combination of frame size and winding makes it suitable for mid-range torque demands on transfer axes, indexing units, and coordinated gantry motion.

Cooling is done by natural convection, so the housing releases heat without external fans and needs unobstructed airflow around the motor surface. This cooling method reduces system complexity and avoids auxiliary fan hardware. The encoder uses a rotatable 240° connector, which helps route the feedback cable in tight machine spaces and can reduce cable strain. Position data is transmitted through Hiperface, and the feedback system provides 128 signal periods per mechanical revolution for smooth speed control and stable commutation. The motor has a plain shaft, which is suited to clamping couplings, pulleys, and similar drive elements that rely on precise concentric alignment.

The feedback system uses optical scanning for clear signal generation across the operating speed range. It also uses a multi-turn absolute encoder, so the drive can retain position information over multiple shaft revolutions after power is removed. That arrangement can support restart without a homing move when the control system uses the stored position reference. Winding code 0450 identifies the electrical winding used for this motor, and motor size 070 is paired with frame length D for compact installation in machines with limited mounting space. Because the unit is supplied without a holding brake, any vertical or suspended load must be held by the drive or by an external mechanical device.
