R911287899
The R911287899 (MHD093C-035-PP1-BA) is a high-performance synchronous motor from Bosch Rexroth Indramat. It features main power and encoder connections via separate plug-in modules. Power is supplied to the unit through either a flange socket with a screwed connection or a bayonet catch, utilizing a three-core cable of minimum 0.75mm2 cross-section. The motor can function at altitudes up to 1,000m above sea level, although utilization factors need to be adjusted at higher elevations. This unit is designed to handle loads only when equipped with shock absorbers or strengthened against potential shock damage.
This motor is equipped with IP 65 protection for its housing, output shaft, and power and feedback connectors. It incorporates a DIN 6885-1 standard compliant keyway shaft along with a sealing ring. The motor is designed to withstand a certain level of shock load during operation, storage and transportation. Additional detailing includes possible replacement of flange socket covers with sealing air connectors, provided the O-rings are securely placed. For vertical installations with the shaft pointing upwards, fluid accumulation at the output shaft must be prevented to avoid internal damage. With a prime black RAL 9005 varnish coat over its housing, this motor can support secondary cooling devices such as blowers in high-load environments.
