R911308685
The Bosch's R911308685 (MSK030B-0900-NN-S1-UP0-NNNN) is part of the MSK series, a synchronous motor distinguished by robust performance and fine degree of size variations. These motors, characterized by high torque density, compact construction, and torque delivery of up to 631 Nm, can be equipped with single or multi-turn encoders with various resolution levels. MSK motors possess an IP65 protection rating and contain an integrated temperature sensor. Higher capacity motors within this series offer liquid cooling while the specified MSK030B-0900-NN-S1-UP0-NNNN model utilizes convection cooling. Operating environment conditions specify a 0-40 degrees Celsius temperature range with adequate space for airflow and an elevation range of up to 1000 meters. The single-turn optical encoder supports Hiperface protocol.
The R911308685 (MSK030B-0900-NN-S1-UP0-NNNN) motor offers a 240-degree-rotating electrical connector and a motor shaft equipped with both a keyway and shaft sealing ring. All keyway-equipped motors in this series are balanced with a full key, while driven machine elements should be balanced without a key. The motor features a 40mm diameter, a 9mm motor shaft diameter, and measures 152.5mm in length. The model does not come with a standard holding brake, although one can be ordered separately. With 6.8 Amps and 1.8 Nm as maximum current and torque ratings respectively, the motor can reach a peak velocity of 9000 RPM, weighs 1.3kg, and its installation and maintenance are recommended to be handled by a professional for safety reasons.
