Bosch Rexroth's model R911290881 (MHD115B-024-PP1-RA) synchronizes MHD115B motor with various industrial products including spindle and synchronous motors, drive controllers, and frequency converters among others. Notable specs include a 40-minute thermal time constant in surface cooling, 53.1 Nm rated torque at a current consumption of 32.5 A, and an absolute multiturn encoder for motor feedback. Special attention is required with the IM V3 design setup, as fluid at the output shaft risks motor damage. The shaft also includes safety keyways and a sealing ring, with voltage and torque constants of 154 V/1000min-1 and 1.7 Nm/A respectively at 20 degrees Celsius. IP65 protection and Class F insulation certify full protection from dust particles and low-pressure water jets. This model weighs 40kg, features a 70 Nm holding brake, 1.29 A and 24 volts of current and voltage consumption respectively, and creates 17.9 Nm of torque at 60 K temperature. It carries a replacement warranty in case of any faults.
