Product Description:

The MSK100D-0300-NN-M1-RP2-NSNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical power into controlled rotary motion for indexing tables, packaging machinery, and other automated stations that demand high positional accuracy. In these servo axes, the motor integrates directly with Rexroth drive controllers to supply finely regulated torque and speed. It is intended for closed-loop motion tasks where the drive corrects output quickly as load conditions change.

Cooling is by natural convection, so the housing must be mounted where ambient air can remove heat generated by the 100-frame stator. This cooling method avoids the need for an external blower or liquid circuit. The enclosure carries an IP65 rating that protects the winding and bearing assemblies against dust and low-pressure water jets within the specified ambient range of 0–40 °C. A factory-mounted, electrically released holding brake supplies 70 Nm of static torque for vertical or load-holding axes. Drive torque is transferred through a shaft with keyway that mates with standard hub components. The unit uses motor length D and winding code 0300, and its power connector is located on the right side.

Feedback is provided by an optical encoder that communicates over the Hiperface interface and resolves motion into 128 signal periods per revolution. The encoder provides multiturn absolute feedback, so the controller can retain position information after power is removed. The digital feedback channel supports commutation and closed-loop position control during operation. The windings use Class F insulation rated at 155 °C, which supports continuous service under convection-cooled thermal load while preserving dielectric integrity. The insulation system also helps maintain stable electrical separation during repeated acceleration and holding phases.
