Product Description:

The MSK101C-0202-NN-S3-FG0-NPNN synchronous motor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. This flange-mounted unit functions as a servo drive element in closed-loop automation systems. It converts electrical energy into regulated torque and speed for CNC axes, material-handling gantries, and other motion-control applications. Its design is intended for precise rotary movement where stable response and controlled acceleration are required.

It is wired through a terminal box, allowing field-exchangeable power and feedback connections without pre-molded plugs. Heat created by copper losses is removed solely by natural convection, so no external fan or liquid cooler is required, and the motor can be used where a simple cooling arrangement is preferred. The mechanical interface uses a B5 flange assembly, which positions the stator with a centering pilot for concentric shaft alignment at the mounting face. Position feedback reaches the drive through a Hiperface bidirectional channel, and the encoder provides 16 signal periods per electrical revolution for smooth commutation and stable low-speed operation.

The feedback module uses capacitive measuring principles, which are less sensitive to oil mist and vibration than optical code disks. Its single-turn design retains absolute position within one mechanical rotation, which suits rotary axes that return to a reference position during normal operation. The motor has a plain shaft without a key, making it suitable for backlash-free clamp couplings, and it does not include a holding brake, which helps keep inertia lower for fast moves. Winding code 0202 corresponds to the electrical values required by a compatible IndraDrive controller, while the 101 frame diameter and C length determine the motor's continuous torque range under natural cooling.
