Product Description:
The MSK040C-0450-NN-S2-UP1-NNNN is a synchronous servo motor from Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It delivers controlled torque and position feedback for automation axes that require accurate motion in packaging, handling, and machine-tool systems. The standard design combines a compact frame with integrated feedback, allowing the connected drive controller to regulate speed and position without external sensors. This arrangement supports precise starts, stops, and repeatable movement in tightly spaced machine layouts. Because the feedback hardware is built into the motor, the overall axis package stays compact and easier to integrate in limited installation space.
Thermal dissipation is handled through natural convection, so the housing transfers heat to still air and no forced cooling accessories are required. This cooling method keeps the motor package simple because there is no separate fan assembly to mount. For position feedback, the motor uses an optical encoder with the EnDat2.1 digital interface, which sends absolute data directly to the drive with low latency. The encoder provides 2048 signal periods per revolution for smooth velocity control, while an electrically released brake supplies 4 Nm of holding torque when power is removed. The aluminum housing and radial seals achieve IP65 protection, helping block dust and resist water jets in typical industrial washdown areas.
Rotary feedback is single-turn, so position is retained within one mechanical revolution and additional turns are referenced again after the next power cycle. Continuous operation is permitted in ambient temperatures from 0 to 40 °C, which suits many enclosed production environments. Mechanical power is delivered through a shaft with keyway for secure torque transfer to standard couplings, and the winding insulation follows thermal class 155. The C-length stator package and winding code 0450 give this motor an electromagnetic layout suited to mid-range servo axes that need a balance of compact size, responsive motion, and stable thermal behavior.
