The MHD115B synchronous servo motor, MPN R911287320 (MHD115B-058-NG0-AA), manufactured by Bosch Rexroth, operates at a nominal speed of 1500 rpm and delivers 6.6 kW of power with a rated current of 30 A at 130 V under natural convection and 100 K conditions. The motor features IP65 protection, F-class insulation, and uses a thermistor for temperature monitoring. It provides both natural and surface cooling options, with a thermal time constant between 45 and 100 minutes. Weighing approximately 40 kg, it achieves up to 160 Nm maximum torque at a peak current of 280 A. The design includes a plain shaft with a shaft seal, centering diameter of 180 mm, flange size of 192 mm, B-length motor body, and side A output power connector. Digital servo feedback (HSF) is employed for relative position detection, and no holding brake is fitted.
