The Bosch Rexroth Indramat MSK075D-0450-NN-M1-UG1-NNNN from the MSK IndraDyn S Synchronous Motors series is a precision-engineered IndraDyn S Synchronous Servomotor designed for demanding automation tasks. This standard design unit features a motor size 075 and motor length D to optimize torque density and installation flexibility. The plain shaft configuration simplifies direct coupling to gearboxes or couplings, while the rated speed code 0450 ensures reliable operation at medium speeds. With a footprint tailored for integration into compact drives, this servomotor excels in packaging, robotics, and conveyor applications.

The MSK075D model is cooled by efficient natural convection, eliminating the need for oil or water circuits and reducing maintenance overhead. Signal integrity is maintained via a rotatable, 240° encoder connector mated to high-precision optical encoder technology. Its multiturn absolute encoder turn type and Hiperface encoder interface support robust position control, while 128 signal periods encoder resolution deliver sub-micron feedback accuracy. At standstill and 100 K ambient, the motor provides a continuous current of 18.0 A and develops a continuous torque of 18.5 Nm, ensuring smooth hold and precise positioning under static loads.

Under dynamic conditions, the motor tolerates a maximum current of 74.3 A and delivers up to maximum torque of 64.0 Nm, making it ideal for high-acceleration profiles. Its substantial winding inductivity of 2,900 mH contributes to low current ripple and reduced torque pulsation, enhancing system longevity. For safety and load retention, the unit incorporates an electrically-released holding brake with holding brake torque of 23 Nm, securing the shaft during power-off or emergency stops and ensuring operator protection and process reliability.
