The Bosch Rexroth MPN R911404263 (MKE098B-047-BG0-BUNN) is a synchronous servo motor designed for applications in potentially explosive areas. The motor supports unloaded operation between 800 and 1000 rpm and is specified to remain operational after storage periods of 1 to 5 years. Key specifications on the nameplate include a maximum torque of 43.5 Nm, winding inductivity of 1.20 mH, and discharge capacity of 6.7 nF. The unit features a plain shaft with a shaft seal, an optical singleturn EnDat2.1 encoder with 2,048 increments, and UL/CSA compliant housing. Electrical connections are made via a terminal box on the B-side. Assembly requires DIN 912 M10 x 30 screws tightened to 51 Nm in a clean, dry, and dust-free environment, with proper grounding of the device and coverage of electrical components during handling. The motor's design emphasizes a beneficial torque-to-inertia ratio for high dynamic performance and supports continuous start-stop operation due to its electric commutation. The weight of the unit, without a holding brake, is 18.0 kg.
