Product Description:
The MSK101D-0450-NN-S1-BP0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor is intended for closed-loop industrial automation axes where continuous torque accuracy and high positional repeatability are required. By combining a permanent-magnet rotor with a high-resolution optical encoder, the unit converts drive current into precisely regulated rotary motion for assembly lines, packaging machines, and material-handling equipment. The feedback system allows the connected drive to correct speed and position deviations quickly during changing loads and frequent indexing moves.
The frame is identified as size 101 with a mechanical build length of length D, providing a larger lamination stack for higher torque density than shorter variants in the same diameter. Heat produced by the stator is removed through natural convection, eliminating the need for forced air or liquid cooling hardware and simplifying cabinet layouts. Power and feedback cabling exit through the motor’s B-side power connector, allowing compact cable routing when the motor is mounted near machine guards or support frames. Axial torque is transferred through a keyed shaft seat, and the keyway helps prevent slippage between the motor and the driven component during repeated start-stop cycles.
Position feedback is generated by a Hiperface interface that transmits incremental and absolute data over two-wire digital communications. The optical scanning track contains 128 signal periods per revolution, and the sensing method is optical, giving high edge clarity for fine interpolation inside the drive. The code wheel is configured as single-turn, so absolute position is retained over one full revolution before the value repeats. For axes where mechanical locking or gravity-loaded holding is handled externally, the motor is supplied without a holding brake, which reduces overall length and inertia while leaving the electromagnetic design unchanged.
