Product Description:

The MSK040B-0450-NN-M1-UP1-NSNN is a servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an electromechanical actuator, it converts drive current into controlled torque and speed for positioning tables, pick-and-place arms, and other automated axes. Its integrated encoder returns real-time feedback to the drive controller, helping the axis maintain accurate motion during speed control and positioning tasks. This layout suits machinery that needs repeatable starts, stops, and short indexing moves without adding a separate feedback device.

The motor housing is sealed to IP65, so dust and water jets do not reach the internal windings. Heat is removed by natural convection, which eliminates the need for forced-air hardware and keeps the installation simple. Position data travel over the Hiperface interface, and the encoder uses a multi-turn absolute design so the drive can recover position after a power interruption. A spring-applied, electrically released brake provides 4 Nm of static holding torque for axes that must remain in place at standstill. Motor size 040 with length code B keeps the package compact, while winding code 0450 and insulation class 155 support the electrical and thermal characteristics of this frame.

The feedback system uses optical signal generation with 128 signal periods per mechanical turn, supporting stable interpolation during motion control. The motor is intended for ambient temperatures of 0–40 °C, so additional cooling is unnecessary unless nearby equipment adds external heat. Power and feedback conductors exit through a rotatable 240° connector, which helps route cables in confined machine spaces and reduces strain from awkward bend angles. Mechanical output is provided through a shaft with a keyway, allowing positive torque transmission to couplings or pulleys without slip. The keyed output also suits drive elements that require positive engagement rather than friction-only clamping.
