The Bosch Rexroth Indramat R911345296 (MSK040B-0450-NN-S1-UP0-NSNN) is a synchronous servo motor from the IndraDyn S series, featuring a motor frame size of 040 and a frame length B. This servo motor features natural convection for its heat regulation mechanism and an optical encoder with 128 signal periods, a Singleturn Hiperface, as well as a keyway shaft with a sealing ring. It also includes a 240-degree rotatable plug-type electrical connection. Notably, the motor's standard design meets the DIN EN 60079 ff for cluster II, 3D, and 3G categories. Operating specifications include a winding resistance of 14.7 Ohm, a torque of 1.26 Nm/A, and a voltage constant of 77.8 V/speed at 20 degrees C. The R911345296 (MSK040B-0450-NN-S1-UP0-NSNN) has a protection class of IP 65, thermal class of 155, and operates efficiently between 0 and 40 degrees C ambient air temperatures. Weighing approximately 2.8 Kg, it achieves a max torque of 5.1 Nm, max current of 6 Amps, and max velocity of 6000 rpm, without an electrically released holding brake.
