The Bosch Rexroth MPN R911288111 (MHP093B-035-HG1-BNNNNN) is an MHP series synchronous motor designed for demanding industrial settings. It features an IP65-rated sealed enclosure and black finish, which provide resistance to weathering, dilute acids, and alkaline solutions. The motor operates at 349/359 V, drawing a nominal current of 4.4/7.5 A, and provides a nominal torque of 8.8/14.5 Nm at a nominal speed of 2500 rpm. The device includes a plain shaft with sealing ring for backlash-free torque transmission, and is equipped with an electrically released holding brake and an incremental optical encoder with 2048 resolution. Peak torque reaches 66 Nm at 39.6 A. Standard bearings are rated for 30,000 hours of operation. The unit is cooled by ambient air and is specified for use at temperatures from 0–40 °C and altitudes up to 1000 m without derating.
