R911280503
The R911280503 (MDD112B-N-015-N2M-130GA0) is a digital servo motor designed and constructed by Bosch Rexroth Indramat, renowned for its built-in multiturn encoder. This encoder is instrumental in supplying feedback over several revolutions of the motor shaft. This feedback, relayed through a dedicated cable, is crucial to control the motor's parameters such as torque and speed. The motor operates on nominal speed of 1500 RPM, with its power supplied through a power cable from the drive to the motor. It features a frame size of 112, a frame length of 'B', and a housing design capable of natural convection or surface cooling, yielding differing performance ratings.
This motor's shaft is a plain, standard 'B' end design, and although a block brake is not included, these can be purchased separately for MDD112 motors. The power connection, located on side 'A' of the housing, attaches to the drive's power cable. It functions optimally between 0°C and 45°C and up to 1000 meters above sea level. Output data will reduce if environmental conditions surpass these figures. The R911280503 (MDD112B-N-015-N2M-130GA0)'s average output decreases by 20% at 55°C and by 35% above 5000 meters altitude. This servo motor weighs approximately 36 kilograms.
