R911276758
Produced by Bosch Rexroth Indramat, the R911276758 (MHD090B-058-PP1-UN) belongs to the prestigious MHD Synchronous Motors series. Recognized for their high precision and maintenance-free design, these motors are especially valuable in fields such as robotics and machining centers.
The R911276758 (MHD090B-058-PP1-UN) model is available in naturally cooled and surface cooled versions. The surface cooled version incorporates an additional air blower that facilitates cooling through forced convection, enabling higher power production without overheating. The naturally cooled version has two alternatives: 60K and 100K, representing their overtemperature values. Torque ratings for these variants are 4.2Nm and 8.9Nm, while their power performance stands at 2.1kW and 4.9kW respectively. The torque and power rating for the surface cooled version are 13.4Nm and 7.0kW, respectively. All types of R911276758 (MHD090B-058-PP1-UN) motors operate optimally at a speed of 4000 RPM and frequency of 267 Hz, thanks to the 4-pole design. Despite their powerful performance, these motors are easily transportable, weighing only 14 kg.
The model is equipped with a driveshaft that integrates a DIN 6885-1 keyway, designed to facilitate attachment to the power-receiving hub. An 11.0Nm holding brake ensures stability when the motor is not operating. For precision feedback, the R911276758 (MHD090B-058-PP1-UN) uses a digital servo feedback system with an inbuilt multiturn encoder which can record up to 4096 revolutions.
