Product Description:
The MSK101D-0450-NN-S2-AP2-RNNN is a synchronous servo motor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In automated machinery, this motor converts drive controller commands into accurate rotary motion for axes that demand steady speed regulation and quick positioning. Its compact frame and integrated feedback allow it to fit tightly into packaging lines, printing presses, handling modules, and many other motion-centric applications. Because the feedback device is integrated into the motor, the paired drive can monitor rotor position continuously during speed changes and short indexing moves. That arrangement supports repeatable motion on transfer, cutting, and registration tasks.
The motor housing is cooled by natural convection, so airflow around the frame must not be obstructed. Frame size 101 and length code D provide a balance between torque density and installation depth, while the increased concentricity design helps reduce radial runout at the shaft. Position feedback is handled by an optical EnDat2.1 single-turn encoder that generates 2048 signal periods, delivering high-resolution angle data to the drive controller for commutation and position control. An electrically released holding brake rated at 70 Nm secures the axis when power is removed. The enclosure has an IP65 rating, and the power connector is located on the A-side for external wiring. This layout supports installation in machines where cable routing space is limited and the motor surface may be exposed to dust or washdown spray.
Continuous duty is supported within an ambient range of 0 to 40 °C, which matches common conditions inside machine enclosures. The output uses a shaft with keyway, which allows torque transmission through standard keyed couplings, pulleys, or hubs. Class 155 insulation supports the thermal demands of repeated operation, and winding code 0450 identifies the electrical winding used in this motor. The motor can be connected to common power-transmission elements without requiring a shrink-fit shaft interface.
