Product Description:

The MSK101C-0300-NN-M1-AK0-NN02 is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servomotor, it works with IndraDrive controllers to position machine axes in automated assembly, packaging, and material-handling stations. The design provides high torque density in a sealed frame suited for demanding motion sequences. Its enclosed construction also supports equipment that requires accurate starts, stops, and repeatable axis motion over long duty cycles.

Passive thermal management is delivered through natural convection, eliminating the need for forced air or liquid cooling circuits. Rotor position feedback is transferred on the Hiperface bus; the scan head resolves 128 signal periods per mechanical revolution with an optical sensor path. Because the encoder counts multiple turns mechanically, it supplies multiturn absolute position data so the drive can recover axis coordinates at power-up without homing. Electrical power enters through a plug on the A-side of the housing, which lets cables run parallel to the shaft. Size code 101 sets the stator diameter and bolt circle, while length code C indicates the active stack used for continuous torque. The unit is supplied without a holding brake, so external means must secure the load when power is removed.

The housing and shaft seal achieve an IP65 ingress rating, permitting installation in areas exposed to dust or low-pressure water jets. Rated operation is specified for ambient temperatures of 0–40 °C; service outside that range requires derating or auxiliary cooling. Windings are insulated with class 155 materials, matching expected winding temperature limits in enclosed machines. Winding code 0300 identifies the phase resistance and inductance used with medium-voltage IndraDrive supplies. These electrical values must match the connected drive.
