Product Description:

The Bosch Rexroth Indramat MSK101D-0300-NN-M1-AG3-NNNN is an IndraDyn S synchronous servomotor in the MSK IndraDyn S Synchronous Motors series. This motor provides closed-loop rotary motion for positioning axes, and its electrical design supports responsive torque delivery for packaging stations, gantry drives, and material-handling tables. As a standard configuration unit, it combines a compact frame with an absolute feedback system so the associated drive controller can determine shaft position immediately after power-up without a homing cycle. The integrated feedback also helps the drive regulate speed and position during acceleration, steady motion, and stopping on repetitive machine cycles. That behavior is useful on transfer systems that must restart accurately after planned stops or brief power interruptions.

Heat generated by the stator windings is removed through natural convection, avoiding external blowers and maintaining the motor’s IP65 enclosure, which seals the housing against dust and low-pressure water jets. The frame corresponds to size 101 with length code D, while the electromagnetic design uses winding code 0300 to match compatible MSK drive amplifiers. Mechanical power is transferred through a plain shaft, and the power cable enters on the A-side, simplifying wiring when the connector faces the drive. The unit operates in ambient temperatures from 0 °C to 40 °C, and its insulation system meets class 155 so the conductors stay within safe thermal limits during cyclic loading. This layout suits machines that need sealed motor construction without added fan assemblies.

Precise rotor position is reported by an Hiperface optical encoder that offers 128 signal periods per revolution and multi-turn absolute position memory, allowing the control loop to recover the exact angular count after a power loss. An electrically released holding brake supplies 120 Nm of static torque to secure vertical axes when the drive is disabled. The encoder gives immediate position availability at startup, which lets the axis return to controlled motion without a separate reference run. Because the brake is separate from torque production, the motor can hold a stopped load when control power is removed while the servo system manages movement during normal operation.
