The R911293229 (MHD115B-024-PP1-LA) model by Bosch Rexroth is a high-performance synchronous motor recognized for its energy efficiency and durability. It presents a lightweight 3.8 kg holding brake and offers 70 Nm of holding torque, powered by a rated current and voltage of 1.29 A and 24 V, respectively. The windings have an inductance of 5.36 mH and resistance of 0.36 ohms. The internally cooled motor can consistently produce 75 Nm of torque at both 60/100-K temperatures, handling shock-absorbing loads when installed appropriately. Other technical aspects include thermal time constants of 100 minutes for natural cooling, and 45 minutes for surface cooling. With 4.4 kW of power at 60 K and an 8.2 A current consumption, the motor operates ideally at a maximum temperature of +40 degrees Celsius and is IP65-rated. A built-in multiturn absolute encoder controls the operational speed and shaft position.
