Product Description:

The MSK040C-0450-NN-M2-UG1-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within automated assembly cells and packaging lines, it converts drive commands into precise rotary motion for axes that require accurate position and speed control. The motor follows the standard mechanical design of the series, uses frame size 040 with length code C, and carries winding code 0450 for compatibility with matching IndraDrive controllers. It is suited to compact servo applications where repeatable acceleration, steady running, and accurate stopping are required during frequent machine cycles.

Heat is removed through natural convection, so no external fan or liquid loop is required. The encoder connector is rotatable through 240°, which helps with cable routing in tightly packed machine frames. Position feedback uses the EnDat2.1 digital interface, allowing the drive to receive position data, diagnostic information, and electronic motor data over a streamlined connection. Inside the feedback system, the optical scanner provides 2048 signal periods per revolution and uses a multiturn absolute arrangement so the controller retains shaft position and revolution count after power-up. The plain shaft supports direct coupling to precision gearboxes or timing pulleys where low-backlash motion transfer is needed.

A spring-applied, electrically released brake provides 4 Nm of holding torque to secure an axis when power is removed. The housing meets IP65, which helps protect internal components from dust and low-pressure water jets in industrial settings. Continuous service is permitted in ambient temperatures from 0 to 40 °C, and the winding insulation is based on class 155 for appropriate thermal endurance during normal operation. This combination of brake function, enclosure protection, and thermal capacity supports reliable use on controlled motion axes that pause, hold position, and restart repeatedly during production.
