R911276758 (MHD090B-058-PP1-UN)

Description

The MHD Synchronous Motors series by Bosch Rexroth is renowned for its state-of-the-art servomotors and servo drives. One such product is the R911276758 (MHD090B-058-PP1-UN), a motor available in naturally cooled and surface cooled versions. The surface cooled variant incorporates an additional air blower for forced convective cooling, enabling it to remain cool even when delivering higher power. The naturally cooled model is available in two versions: 60K and 100K. These designs feature 4.2Nm and 8.9Nm of rated torque and 2.1kW and 4.9Kw of rated performance respectively. The surface cooled motor has rated performance of 7.0kW and rated torque of 13.4Nm. The optimal operational speed for all MHD090B-058-PP0-UN motors is a rated frequency of 267 Hz at 4,000 RPM. Notable design features include a DIN 6885-1 keyway and an 11.0Nm holding brake. Feedback is provided by a digital servo feedback device with an integrated absolute multiturn encoder.
