The MDD090B-N-030-R2L-110PB0 is a high-precision synchronous servo motor crafted by Bosch Rexroth. Primarily intended for high-accuracy applications such as grinding machines, this servo motor boasts a nominal speed of 3,000 RPM and a rotor inertia of 36 x 10-4 kgm2. Its rotor features rare earth and iron oxide permanent magnets, resulting in low inertia and offering a superior torque-inertia ratio for dynamic operations. The brushless design and self-lubricated bearings make it a maintenance-free unit, while its entirely sealed housing protects against external solid substances, including conductive dust and water jet sprays. The motor's electronic commutation delivers high cyclic load capacity to handle continuous start-stop operations with high repetition rates. Its output shaft, inclusive of a keyway per DIN 6885 standards, ensures a form-fitting torque transmission, and features a radial shaft sealing ring preventing hydraulic oil intrusion. Lastly, its integrated digital servo feedback encoder system with an optical measurement method ensures high-precision positioning with a system accuracy of ±0.5 angular minutes.
