Product Description:

The MSK101D-0300-NN-M1-BG3-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop servo axes, the unit converts commanded electrical energy into controlled torque and speed for conveyor sections, pick-and-place heads, and machining spindles in industrial automation. Its integrated feedback supports precise control during acceleration, steady running, and position changes. The holding brake helps keep the axis secured at standstill when the drive is disabled.

Heat generated during motion is removed by natural convection, so no forced-air channels or liquid circuits are required. Position data travel through the Hiperface interface, and the optical encoder supplies 128 signal periods per revolution, giving the drive controller fine resolution for smooth velocity control and synchronized multi-axis motion. The encoder stores multi-turn absolute position information, so homing after power restoration is not required. An electrically released holding brake delivers 120 Nm of static torque to immobilize vertical or high-inertia loads when power is removed. The motor has an IP65 enclosure rating, which blocks dust ingress and water jets so it can be installed on exposed machine frames without an added housing.

Mechanical integration is simplified by the motor size 101 frame and length code D, while the power connector is oriented on the B-side for cable routing parallel to the machine bed. A plain shaft couples to gearboxes or rigid couplings without keyways, which reduces fitting complexity. Continuous operation is permitted within an ambient range of 0–40 °C, and insulation class 155 helps protect the winding set identified by code 0300 during rated operation. This layout suits installations where cables must stay close to the machine structure and where compact motor mounting is preferred.
