Product Description:

The MSK101C-0300-NN-M1-BP2-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for precise torque and speed regulation in automated machinery such as packaging lines, gantry axes, and material-handling systems, where rapid positioning and repeatable motion are required. This type of motor is typically paired with a servo drive that adjusts current continuously so the axis can accelerate, decelerate, and hold position with consistent response under changing load conditions. A keyed output shaft helps transmit torque to the driven load without slip, and the power connector is mounted on the B-side to support orderly cable routing in compact machine layouts.

This model carries a protection rating of IP65, so its housing resists dust ingress and low-pressure water jets. For feedback, the motor uses the Hiperface serial interface that transmits high-resolution position data from an optical encoder with 128 signal periods. That feedback arrangement gives the controller position information for commutation and closed-loop motion control, which helps maintain accuracy during repeated starts and stops. Electrical characteristics follow winding code 0300, and the active frame is size 101 with a C-length housing that balances continuous torque with a moderate installation length. The insulation system is built to Class 155, allowing the stator windings to tolerate elevated operating temperatures during normal duty.

The unit relies on natural convection, so it must be installed where surrounding airflow and mounting conditions can remove heat without a separate fan. Because cooling is passive, the installation should avoid blocked surfaces or confined spaces that trap heat around the housing. An electrically released holding brake provides 70 Nm of static torque to hold the load when the drive is disabled, which is useful on vertical axes and other applications that must remain stationary at rest. A multiturn absolute encoder retains position information across power cycles, and optical sensing avoids magnetic hysteresis effects. Continuous operation is approved from 0 to 40 °C, which suits typical industrial cabinet conditions.
