The Bosch Rexroth MPN R911247774 (1MR240B-A087) is a rotor from the 1MR series, engineered for direct drive applications in 1MB frameless spindle motors used in milling, grinding, and turning equipment. The rotor features a laminated core with a sleeve and a step interference fit, and includes balancing rings with tapped holes to enable vibration grading as specified by DIN VDE 0530. With an inside diameter of 87 mm, motor size 240, motor length B, and a moment of inertia of 0.135 kgm², this model supports efficient power transmission. The red lacquer-coated, corrosion-protected core increases environmental resistance, but the IP 00 rating requires external protection in humid or dusty conditions.
