Product Description:

The MSK101D-0300-NN-S1-BG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. The model follows a standard design and uses the 101 frame size with length code D for precise positioning on packaging lines, gantry axes, and automated assembly stations. It serves as a medium-inertia drive element for closed-loop torque control, making it suitable for axes that must start, stop, and reverse smoothly while maintaining stable positioning under changing loads. Its synchronous design also supports fast response in coordinated motion systems where repeatable servo behavior is required throughout frequent operating cycles.

Thermal regulation is handled by natural convection, so the housing fins dissipate heat without external blowers and allow operation without added cooling hardware. The enclosure carries an IP65 rating, which keeps out dust and protects against water jets common in production areas. Rotor position is reported through a Hiperface interface with 128 signal periods, and the sensing principle is optical, so stray magnetic fields do not interfere with feedback accuracy during normal operation. Winding code 0300 identifies the electrical characteristics expected by the matching drive, while the B-side power connector routes cabling toward the machine frame and helps keep adjacent moving parts clear.

The encoder delivers a single-turn absolute value, which is suitable when the axis can execute a reference move after power-up and does not need multi-turn position retention. Continuous operation is permitted between 0–40 °C, covering common ambient conditions around open machine sections and enclosed installations. Insulation class 155 supports elevated winding temperatures during short overloads without placing unusual demands on the insulation system. A plain shaft without a keyway minimizes backlash when clamping couplings are used, and the motor is supplied without a holding brake to reduce mass and simplify axial mounting.
