The R911321668 (MSK040B-0450-NN-M1-UP1-NNNN) is a synchronous servomotor by Rexroth Indramat, delivering an impeccable balance of speed and torque, in a compact and lightweight (3.1kg) design. This model, with a frame length of 155.5mm and rotor length of 30mm, is capable of producing continuous torque of 1.7Nm at standstill and a maximum torque of 5.2Nm for brief periods of 40ms. A speedy unit, it operates at 6000min-1, producing sound levels below 75db, equivalent to regular conversation volume. Utilizing natural convection for cooling, the R911321668 (MSK040B-0450-NN-M1-UP1-NNNN) features precision position feedback via a 128-increment optical encoder. The 240° rotatable output ports and standard-sized rotor shaft add to its versatility, while the electric release holding brake enhances safety. This last feature ensures motor standstill making the unit ideal for tasks needing precise motion and torque efficiency.
