The R911293229 (MHD115B-024-PP1-LA) is a synchronous servo motor from Bosch Rexroth featuring a keyed shaft and shaft seal, with a motor size of 115 and length B. It is equipped with a digital servo feedback system and multiturn absolute encoder for position detection exceeding 4096 revolutions. The model provides a holding brake torque of 70 Nm and continuous standstill torque of 50 Nm. Electrical parameters include a winding inductance of 5.36 mH, resistance of 0.36 ohms, rated voltage of 24 V, and rated current of 1.29 A. It delivers 4.4 kW at 60 K with a maximum current draw of 8.2 A. The motor employs natural convection cooling with a thermal time constant of 100 minutes, and optional surface cooling reduces this to 45 minutes. The centering diameter is 180 mm with a flange size of 192 mm. The ingress protection is IP65, and the maximum ambient operating temperature is +40 °C. Power is supplied via a left-oriented power connector.
