Product Description:

The MSK101D-0300-NN-M2-AP2-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop positioning and speed control, it operates as the prime mover on precision axes in packaging machines, metal-cutting centers, and automated material handling lines where exact torque delivery and high feedback accuracy are required. The mechanical envelope follows motor size 101 with length code D, providing a balance between continuous torque output and overall package length for medium-frame installations. This arrangement supports repeatable acceleration and stable speed regulation in machines that must maintain consistent axis response through changing loads.

Heat is removed through natural convection, so the motor can be mounted without external fans when ambient airflow is sufficient. Feedback is transmitted over the EnDat2.1 digital interface, and the optical encoder supplies 2048 signal periods per revolution, giving high-resolution multi-turn position data to the drive. Because the feedback channel is digital, the connected drive can evaluate rotor position directly for commutation and accurate motion control. An electrically released holding brake supplies 70 Nm of static torque to secure vertical or suspended loads during power loss. The housing is sealed to IP65, preventing dust ingress and protecting internal components from low-pressure water jets. The brake holds the load at standstill when drive torque is removed and helps prevent unwanted movement on vertical axes.

The thermal operating window of 0 to 40 °C matches typical control cabinet climates, and insulation class 155 supports winding temperatures up to 155 °C during intermittent overloads without degradation. A keyed shaft, identified as a shaft with keyway, delivers positive drive coupling to pulleys or gearboxes, while the A-side power connector helps reduce cable loops in machines where motor cabling exits toward the drive cabinet. The winding code 0300 sets the electrical constants that the drive controller must match, and the increased concentricity design limits rotor runout for smoother rotation at high speeds. This layout supports orderly cable routing and helps the motor maintain smooth operation during repeated motion cycles.
