Product Description:
The MSK101D-0300-NN-M1-AG2-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It supplies controlled torque and speed for automated axes in packaging equipment, material-handling gantries, and metal-cutting spindles, linking directly to IndraDrive controllers to close precise position loops. In servo systems, the motor converts commanded current into shaft motion that follows programmed paths with low lag under changing loads. This makes it suitable for applications that require repeatable acceleration, steady running speed, and stable position control during stop-and-go cycles.
The motor relies on natural convection to remove heat, so rated performance is available when free airflow around the housing is provided. Its feedback section uses a Hiperface digital interface that transmits both position and diagnostic data to the drive. Position accuracy is supported by an internal encoder that resolves the shaft into 128 signal periods per revolution, and this resolution comes from an optical scanning method that helps reduce quantization error. Because the encoder is multi-turn absolute, the axis retains position information across power cycles without an external battery. The feedback channel also allows the drive to monitor rotor position continuously during speed changes, which supports stable commutation and accurate positioning. The motor has size 101 and length variant D, winding code 0300, and a power connector on the A-side of the stator for straightforward cable routing from the control cabinet.
For static holding duties, the electrically released brake supplies 70 Nm of torque, allowing vertical or indexing axes to remain locked when power is removed. The shaft end is a plain shaft, suitable for backlash-free couplings that rely on clamping friction. The motor carries the Requires Cooling FN designation, so the natural airflow path must not be blocked by panels or insulation. It uses the Standard variant, which keeps interface dimensions consistent with other MSK units of the same frame. This combination suits axes that couple directly to gearboxes, pulleys, or lead screws and need secure standstill holding between moves.
