The R911257027 (1MR375D-S125) is a rotor from the 1MR series designed for use with 1MB frameless spindle motors, specifically with frame size 375 and motor length D. This rotor incorporates a step interference fit design and ensures operational stability through frictional engagement with the motor spindle using a multiple die press group. It has a weight of 132 kg and a moment of inertia of 1.73 kg·m². Cooling is managed by a combination of coolant fluid absorption and heat transfer via cooling rings to the endplate. Two fitting diameters allow safe rotor unmounting, and the unit is balanced with rings featuring tapped holes, conforming to DIN VDE 0530 vibration severity standards.
