The Bosch Rexroth R911312646 (MSK070C-0450-NN-M1-UP1-NSNN) represents the next progression in servo motor technology. This motor includes an array of innovative features. These include a standard and extended design in compliance with EN 60079 ff, an optical encoder with 128 signal periods and angular accuracy of ±120 seconds, a sturdy shaft with keyway and protected by a sealing ring, and a holding brake, all powered by connectors that can be rotated up to 240 degrees. The maximum speed of the optical multiturn encoder is 9000 RPM, capable of distinguishing up to 4096 revolutions and requiring 7 to 12 volts DC supply voltage. The brake has a holding torque of 23 Nm, and operates at a rated voltage of 24 volts and rated current of 0.79 Amps. This motor features natural convection cooling, can operate in temperatures ranging from 0 to 40 degrees Celsius, and is approved for installation up to 1000 meters altitude. The R911312646 (MSK070C-0450-NN-M1-UP1-NSNN) is housed in an IP65 rated casing.
