The R911283778 (MHD093B-058-PP1-AN) is a synchronous motor manufactured by Bosch Rexroth Indramat, as part of their MHD Series. These motors harness electronic communication and a permanent magnet to provide enhanced durability and reliability. Available in multiple configurations, varying in specifics such as holding brake, cooling methods, motor feedback, and output shaft, these MHD Series motors require no maintenance thanks to their fully-sealed, lifetime-lasting bearings. The R911283778 (MHD093B-058-PP1-AN) model boasts modest torque, expertly suited for sophisticated automation applications like machine centers and precision robotics. There are three choices for cooling your motor: natural cooling, surface cooling with an air blower, or liquid cooling utilizing a coolant to manage the motor's temperature. Performance-wise, the natural cooling design has 60k and 100k models, offering 7.1Nm and 9.1Nm of torque and power ratings of 1.7kW and 4.1kW, respectively. The surface cooled motor promises improved performance with a torque of 15.0Nm and performance rating of 7.6kW. The liquid-cooled design is the most potent with a torque of 24.7Nm and a power rating of 12.7kW. The motors' nominal speed varies with the 60k natural cooling model operating at 2500 RPM, while the others perform at 4000 RPM. The frequency exhibits similar variation, with the 60k naturally cooled model rated at 167Hz and others at 267Hz. The R911283778 (MHD093B-058-PP1-AN) comes with digital servo feedback, incorporating a multi-turn absolute encoder.
