The Bosch Rexroth Indramat MKD041B-144-KP0-KN servo motor from the MKD Synchronous Motors series is a high-performance synchronous motor delivering precise motion control for industrial automation. It features a voltage constant of 36.3 V/1000min-1, a torque constant of 0.4 Nm/A and a winding resistance of 1.8 Ω. With a continuous torque at standstill of 2.7 Nm under natural 60 K cooling (2.9 Nm at 100 K), and rated speeds of 3000 rpm at 115 V and 4500 rpm at 170 V, it achieves peak speeds up to 7500 rpm. The motor’s insulation class F and IP65 protection ensure reliability in harsh environments. It includes resolver feedback w/ integrated encoder for absolute (>4096 revs) position detection, a robust connection box interface, and weighs 4.4 kg, supporting operating temperatures from 0 to +40 °C and storage from -20 to +80 °C.
