Product Description:

The MSK070D-0450-NN-S1-AG1-NNAN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop drive systems, this unit translates commanded current into stable torque and speed, allowing accurate positioning of machine axes, pick-and-place arms, and converting equipment. Its D-length housing follows a reduced run-out mechanical design so the shaft remains concentric under load, a feature that limits vibration and improves repeatability in automation lines.

During service, the housing has a protection rating of IP65, which prevents dust ingress and guards against low-pressure fluid jets while allowing heat to escape through the aluminum frame. An electrically released holding brake generates 23 Nm of torque to lock the shaft whenever supply power is removed. Rotor position is relayed over the Hiperface serial link; the built-in optical encoder resolves 128 signal periods per mechanical turn and provides single-turn absolute data to the drive controller. This arrangement supports repeatable positioning after emergency stops or routine power cycles.

Heat produced by the windings is removed by natural convection, making external fans unnecessary and enabling installation in compact cabinets where airflow is limited. The output end carries a plain shaft for backlash-free coupling to gearheads or direct-drive elements, and the power connector is arranged on the A-side to simplify cable routing along linear modules. The motor operates in ambient temperatures from 0–40 °C, and continuous torque must be derated beyond that range to protect the class 155 insulation system. The motor has a 070 frame size and winding code 0450, so its electrical characteristics match Rexroth drive settings for the corresponding current class.
