R911325541
The Bosch Rexroth Indramat R911325541 (MSK071D-0300-NN-S2-UG1-RNNN) is a high-performance, convection-cooled digital servo motor. Designed to function effectively between 0-40 degrees Celsius and altitudes of up to 1000 meters, it delivers an impressive continuous torque. For 60K and 100K over temperature, it provides a continuous torque at standstill of 17.5 Nm and 20 Nm, respectively. The accompanying continuous current scores at 9.1 Amps and 10.7 Amps at the same operating conditions. Enhanced performance can be achieved when using surface cooling, which raises the continuous torque at standstill for 60K overtemperature to 26.3 Nm and continuous current to 13.5 Amps. The maximum motor torque and current ratings peak at 66 Nm and 40.5 Amps respectively.
Characterized by a torque constant of 2.12 Nm/A at 20 degrees Celsius, and a 134 V/1000 RPM voltage constant, the R911325541 (MSK071D-0300-NN-S2-UG1-RNNN) motor exhibits excellent control of power and efficiency. Its motor winding resistance is recorded at 1.26 Ohms, with a 10.7 millihenry winding inductance and a 7.2 nanofarads leakage capacitance. This robust unit offers four pole pairs, a rated speed of 3800 RPM, and a weight of 19.6 kilograms. Additional features include a 23 Nm holding torque, an integrated optical single-turn encoder, and a plain, sealed motor shaft. The durable housing guarantees enhanced concentricity and run-out, along with 240-degree rotatable connectors.
