R911376518
The R911376518 (MSK071C-0300-NN-S2-UG1-RNNN), produced by Bosch Rexroth Indramat, belongs to the IndraDyn S family of motors featuring a sturdy and eye-catching design. The motor, robustly shielded by its IP65 casing, is resistant to dust and protects against water projected from any angle. It operates within a maximum temperature of +40°C, provided the relative humidity stays below 90%. With optimal electrical and mechanical conditions, the motor can achieve a maximum rotational speed of 5000 rpm and generate up to 44 Nm of torque. At 20°C, the motor exhibits winding inductance and resistance of 10.900 mH and 1.60 ohms respectively, alongside a voltage constant of 110.5 V/min-1.
The R911376518 (MSK071C-0300-NN-S2-UG1-RNNN) model comes with a holding brake which provides a braking torque of 23 Nm. The brake weighs 1.9 kg and has an inertia of 0.0003000 kgm2. It is actuated by an "electrically-released" technique. With a simple output shaft, topped with a sealing ring to prevent lubricant leakage, this motor ensures reliable operation. The motor is also equipped with a single-turn EnDat2.1 encoder and a rotatable electrical socket. To withstand higher temperatures, it adopts a natural cooling mechanism with a thermal time constant of 15 minutes.
