The Bosch Rexroth MPN R911255839 (MDD093B-N-020-N2M-110PA0) is a brushless AC servo motor engineered for use with digital drive controllers. It operates at a nominal speed of 2000 min⁻¹, provides a continuous torque of 14.5 Nm at standstill, and supports a maximum torque of 45.1 Nm. The unit features a 110 mm centering diameter, standard housing, and is fitted with a shaft seal and a keyway shaft. Motor feedback is handled by digital servo feedback and an integrated multiturn absolute encoder, which retains position data through power interruptions. Thermal management includes a sensor for heat dissipation from windings to the case. The motor has an IP65-rated, anti-chalk black coating suitable for demanding environments. Electrical connection is via connector on side A.
