Product Description:

The MSK040C-0450-NN-S1-UP1-NSNN is a synchronous servomotor in the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. As a compact electromechanical actuator, it converts drive commands into precise rotary motion for positioning tables, gantries, and packaging axes. The motor integrates an optical encoder, an electrically released brake, and a sealed housing so the control system receives reliable position feedback while the motor remains protected in automated production equipment. Its winding and frame combination suit light-to-medium duty applications where repeatable motion and stable cycle behavior are important.

Heat is removed through natural convection, allowing the housing to dissipate thermal energy without forced airflow. Position feedback is transmitted through the Hiperface interface, so the drive receives absolute and incremental data over a bidirectional serial channel. Inside the encoder, an optical disk provides 128 signal periods, which supports controlled low-speed operation and consistent incremental movement. For axis holding during standby, the electrically released brake provides 4 Nm of torque and releases automatically when the machine is enabled. The housing has an IP65 rating, which helps keep out dust and protects against low-pressure water jets commonly encountered around industrial machinery.

Operation is permitted in an ambient range of 0 to 40 °C, which supports convection cooling under normal factory conditions. The winding insulation is rated at class 155, allowing the conductors to tolerate elevated internal temperatures. Mechanical output is transmitted through a shaft with keyway, which supports secure coupling to pulleys, couplings, or gearboxes. The motor uses winding code 0450, matched to the C-length stator for balanced current demand and voltage use in this frame size. A rotatable 240° connector simplifies cable routing, and the single-turn optical encoder provides a clear absolute position each time the axis is powered up.
