Product Description:

The MSK100C-0300-NN-M3-RG0-NNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It translates drive controller output into controlled rotary motion for positioning, feeding, and spindle axes in automated lines, where accurate torque and speed regulation are essential for consistent cycle times and product quality. The unit is supplied without a holding brake, so any axis that must remain fixed at standstill requires braking torque from the drive or a separate mechanical device.

A protection rating of IP65 seals the housing against dust and water jets, allowing the motor to be mounted outside sealed cabinets in many machine layouts. Cooling relies on natural convection, so heat leaves the stator through the motor surface without auxiliary fans or coolant lines. Position feedback is exchanged through the Hiperface interface, and this two-wire protocol carries absolute position data along with motor data needed by the drive. The sensing element is a capacitive encoder that tolerates external magnetic fields, and internal interpolation works with 16 signal periods to provide fine incremental resolution for smooth velocity control. Because the encoder is multiturn absolute, the controller can read the shaft angle and stored revolution count immediately after power-up without a homing routine.

The standard housing with motor length code C gives the motor a moderate stack height for balanced continuous torque. Frame size 100 matches common 100 mm square flanges used on gearboxes and machine plates, while a plain shaft and a right-side power connector help simplify machine integration and cable routing. Winding code 0300 is matched to IndraDrive inverters sized for this torque class, and class 155 insulation supports thermal durability during extended duty. Continuous service is permitted at ambient temperatures of 0–40 °C, which suits typical factory conditions where convection cooling remains effective.
