R911339385
R911339385 (MSK040C-0450-NN-M3-UG1-NNNN), a product of Bosch Rexroth Indramat, is a high-performance synchronous motor primarily used in a broad range of motion control operations. Its compact design caters to environments with limited installation space but demanding high torque output. The construction of this model includes high-quality permanent magnets, enhancing torque density, hence providing more torque with less weight. While in standstill mode, it exhibits a continuous torque of 2.7 Nm and a sustained current of 2.4 A. It can also function at an overtemperature of 100 K, where its maximum torque reaches 8.1 Nm, and it carries a peak current of 9.6 A.
Promising a top speed of 6000 rpm, the R911339385 (MSK040C-0450-NN-M3-UG1-NNNN) emits a sound pressure level less than 75 db(A). With four pairs of poles, the device weighs about 3.6 kg and can be operated within an ambient temperature range from 0 °C to 40 °C. Its outer seal offers IP 65 standard protection, safeguarding the internal circuits from water jets. The low rotor moment inertia makes it suitable for dynamic loading conditions. Additional specifications include a discharge capacity of 2 nF, thermal time constant of 16 minutes and a reliable torque constant of 1.25 Nm/A.
