R911321760
The R911321760 (MSK103B-0300-NN-S1-UG0-NNNN), a high-performance servo motor, is crafted by industry leader, Bosch Rexroth Indramat. Belonging to the MSK series of synchronous motors, it has a maximum speed of 4700 RPM. The design features a matte black shell, which packs a solid environmental protection rating of IP65, facilitating its installation near operating machinery. It is lightweight, at 22.5 kg, and needs a suitable ambient temperature (0-40 degrees Celsius) for optimal performance, leading to lower maintenance costs.
With a thermal class of 155, the R911321760 (MSK103B-0300-NN-S1-UG0-NNNN) has a thermal time constant of 27 minutes. It includes specifications like 8 millihenry winding inductance, 0.36 Ohms winding resistance at 20 degrees Celsius, and 108 Volts/1000 RPM voltage constant at similar temperature. The robust motor delivers rated torque and maximum torque of 28 Nm and 85 Nm, respectively. The rated current is 17 Amps while it can go up to a maximum of 63 Amps. This model uses natural convection for cooling. An additional feature is a single-turn optical encoder for feedback and a plain shaft with a sealing ring for longevity. Please note, this model does not come with a holding brake. The power and feedback connectors offer 240-degree rotation for convenience.
