The Bosch R911256397 (MDD093C-N-030-N2M-110PA0) is an AC servo motor from the MDD range, designed for efficient operation with a choice of natural convection or surface cooling. The motor provides a choice of cooling methods which considerably influence its output. With natural convection, it offers a continuous torque of 19.5 Nm at standstill and a continuous current output of 32.2 Amps, whereas with surface cooling, these increase to 20.8 Nm and 34.3 Amps respectively, owing to improved heat dissipation. Its nominal speed is 3000 RPM and thermal time constant stands at 50 minutes with natural convection and 45 minutes with surface cooling. Optional additions include a multiturn absolute encoder and digital servo feedback. The R911256397 (MDD093C-N-030-N2M-110PA0) is a flange-mounted motor with a shaft featuring a keyway according to DIN 6885-1. It requires a temperature range of 0 to 45 degrees Celsius to perform optimally and is IP65 rated.
