R911387267
The product in focus is the R911387267 (MSK070E-0300-NN-S3-UP1-NNNN), a robust Bosch MSK series servo motor by Bosch Rexroth Indramat. Characterized by a motor frame size of 070, an uncompromising wind code of 0300, and a frame length of E, this motor securely mounts on a flange measuring 140mm. Further, the motor boasts a centering diameter of 130mm and length of 298mm. Outfitted with an integrated encoder and an electrically-releasing holding brake, this motor delivers advanced functionality. Activated with a 24V DC signal, it produces a holding torque of 23 Nm, safely preventing shaft rotation at standstill.
The embedded encoder in the R911387267 (MSK070E-0300-NN-S3-UP1-NNNN) is a single-turn capacitive type, although multiturn varieties are available for MSK motors. This encoder is impressively rated for 16 signal periods. The motor's shaft contains a keyway and seal, with the latter requiring regular replacement due to wear. Octagonal power and feedback connectors enhance flexibility in its operation. The motor delivers a powerful maximum torque output of 65 Nm, with current output peaking at 49.3 Amps. The operational sound pressure remains under 75 dB, and the motor's packaging is IP65 rated, completely protected against dust. The motor and brake assembly weighs 17.8 kilograms, and the overall thermal category is classed 155 as per EN 60034-1.
