Bosch Rexroth’s MSK series servo motors, particularly the R911310723 (MSK071E-0300-NN-S1-UG1-NNNN) model, offer compact design and high torque density, ideal for machine tools, metal-forming machines, and robotics applications. This model operates at a maximum speed of 4,200 rpm and delivers up to 84.0Nm torque. Its robust housing is rated IP 65 under EN 60529, defending against intrusive objects or water sprays from all directions. The device is fitted with an optical single-turn encoder using the Hiperface interface, delivering system accuracy within ±80 angular seconds. The motor incorporates a thermal sensor of the KTY84 type in the stator windings for thermal overload protection. The motor’s rotor portrays a moment of inertia of 0.00290 kgm2 and presents four pole pairs. The machine's output shaft, equipped with a shaft sealing ring follows DIN 3760 – design A standards. It also features an electrically released holding brake with 23Nm holding torque.
