The Bosch Rexroth R911255586 (MDD093C-L-030-N2M-130GA2) is a robust digital servo motor from the MDD series, characterized by a multiturn encoder for scalable digital servo feedback. Sized at 093 with a frame length C, this motor measures approximately 386mm in total length and weighs around 22kg. The motor flange, featuring 11mm diameter mounting holes, is roughly 140mm in size. It further boasts a plain shaft, whose diameter stands at 24mm. An optional blocking brake, weighing 1.1kg, can function with a release and clamping delay of 70 and 30 milliseconds, respectively, at 24 Volts DC and 0.7 Amps. The motor draws continuous currents of 32.2 Amps and 34.3 Amps at standstill, with natural convection and surface cooling, respectively. It delivers a rated speed of 3000 RPM in 0-45°C and 0-1000m elevation ranges. Power connections are situated on the housing's side A.
