The Bosch Rexroth MPN R911246971 (1MR310F-A125) is a frameless spindle motor engineered for applications requiring high power density and precise thermal management. This unit features a 97 kg rotor with a step interference fit, specified for integration into the stator of the main spindle. The 1MR rotor operates at a rated speed of 900 rpm, delivering 35 kW continuous output and 480 Nm rated torque in a 6A stator winding, supported by 61 A current. The stator is liquid-cooled to minimize heat buildup, aided by an aluminum cooling jacket, and is suited for ambient temperatures up to +40°C and installations up to 1000 meters elevation. Maximum permitted speed is 3600 rpm. This model uses a 6B winding configuration in a Size 310, Length F motor variant.
