The R911277078 (1MR160D-A061) is a rotor component specifically designed for the Bosch Rexroth 1MB frameless main spindle motor, supporting motor size 160, length D, and compatible with 4A or 4B windings. It is engineered for use within a liquid-cooled, asynchronous motor configuration, achieving 3000 rpm with 4A winding and 2000 rpm with 4B, each drawing 48 A current. The rotor delivers 32 Nm torque at a voltage range of 171 to 370 V, with output power between 6.7 and 10 kW, dependent on stator winding inductance values from 1.57 to 7.23 mH. It complies with IP00 protection and features a 60.3 mm internal diameter for precise installation.
