R911309394
The R911309394 (MSK071E-0300-NN-M1-UG1-NNNN) rotor, designed by Bosch Rexroth Indramat, is an integral part of electric drives. For the 60K model, it delivers a working torque speed of 23.0Nm and a standstill current of 12.5A, while its 100K counterpart provides a torque speed and current of 20Nm and 12.6A, respectively. Both versions come with a plain shaft, equipped with a shaft sealing ring and an electrically-released holding brake for maintaining axle stability when the machine is de-energised. The noise emission is contained below 75dB[A].
Technical specifications of the R911309394 (MSK071E-0300-NN-M1-UG1-NNNN) presents intrinsic characteristics that enhance efficiency and durability. With a winding resistance of 0.79Ohms and constant voltage of 126.4V/min at a 20°C temperature, the part can achieve a moment of inertia of 0.00290kg*m2 without brake interference. Other features include a 4-pole design, a 19.8min thermal constant, a peak speed of 4200/min, and a winding inductivity of 6,200mH. Moreover, it incorporates an insulation system compliant with EN 60034-1 F standards. The R911309394 (MSK071E-0300-NN-M1-UG1-NNNN) rotor is also engineered to operate under an ambiance of up to 40 °C, with a coolant inlet temperature that matches up this limit.
