Product Description:

The MSK040C-0450-NN-M3-UP1-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. It is built for machinery axes where fast positioning, repeatability, and stable closed-loop control are required. Its synchronous design lets the paired drive regulate torque and speed precisely during indexing, transfer, and positioning tasks. A multiturn absolute encoder supplies position data across successive shaft revolutions, and an electrically released holding brake keeps the axis in place when power is removed, making the motor suitable for packaging systems, material-handling gantries, and light mechanical presses.

Cooling is handled by natural convection, so the housing relies on ambient airflow rather than forced fans. Using ambient-air cooling also removes the need for separate blower wiring and fan maintenance. The encoder connector is rotatable through 240°, which helps route cables in tight spaces and around nearby machine structures. Digital feedback is transmitted over the Hiperface interface, and the feedback unit uses a capacitive scanning system with 16 signal periods to track rotor position and store motor data on the same connection. The motor has size 040, length code C, and winding code 0450, which indicates the stator's electrical constants for matched IndraDrive amplifiers.

The holding brake is rated at 4 Nm, providing static torque to keep vertical loads secure during stops. The housing is sealed to IP65, which helps block dust and low-pressure water jets during machine operation. Thermal durability is based on insulation class 155, and the motor is intended for ambient temperatures from 0 to 40 °C without derating. A keyed shaft transfers torque to couplings or pulleys and helps prevent slip under peak load or repeated reversals.
