R911370164
The R911370164 (MS2N07-D0BRN-BMVK2-NNANN-F1) IndraDyn S synchronous servomotor, a product of Bosch Rexroth Indramat, is an advanced 10-pole motor under the MS2N07 series. Featuring standard bearings and flange, this device also includes a half-key balancing keyway shaft with a DIN ISO 21940-32 compliant shaft sealing ring. Maximum motor disconnection is activated at a temperature of 145°C, mandating regular cleanup and checkups of the motor and fan. The synchronous motor operates using a multiturn encoder, which facilitates indirect absolute position recording within 4096 mechanical rotations, with an M40/M17 rotatable double cable electrical connection.
True to its specifications, the servomotor has a voltage constant of 83.9V 1000min-1 +/-5% and a torque constant of 1.38NmA +/-5% at 20°C. Its shaft features a frontal centering hole with a DS M10 thread to comply with keyway and DIN 332-2 standards. Additionally, it includes a brake system with a stationary holding-torque of 36Nm and maximum switched energy of 850J. The brake can be tested either manually or through a software function. The N type tolerance, standard-bearing motor's lifespan is contingent on the grease's service life. If fitted with a gearbox, it should be oil-proof or of a closed lubrication-type, as the shaft sealing ring should not continuously touch the gearbox oil. The motor's cooling is operated through IC410 or self-cooling based on EN 60034-6. The holding brake's efficiency may diminish due to overriding temperatures and voltages. A torque wrench can measure the transferable holding torque, de-energizing the device during the process ensures its safety from unexpected restarts.
