Product Description:
The MS2S03-C0BYN-IMHG0-NNDNN-NN is a synchronous servomotor built by Bosch Rexroth Indramat for the MS2S Synchronous Servomotors series. Its low-inertia rotor supports rapid acceleration when moving light mechanical loads. The self-contained encoder provides closed-loop feedback for precise torque and velocity control during high-speed positioning in assembly cells and handling gantries.
With a rated speed of 9000 rpm, the motor supports fast indexing cycles without external gearing. Position feedback comes from a magnetic multi-turn encoder that provides a resolution of 18 bits per revolution and tracks 65,536 revolutions in absolute form. Maximum system accuracy is ±360 arcseconds through the ctrlX SENSEmotor interface. The BASIC encoder draws 130 mA from an 8–12 V supply delivered through the single-cable M17 connector. This rotatable connector has a quick-lock SpeedTec latch that allows tool-free access. Self-cooling eliminates the need for auxiliary blowers, and the motor is supplied without a holding brake to minimize inertia. Winding code BY, frame size 03, and frame length C are combined with an IM B5 / IM 3001 flange pattern. Standard deep-groove ball bearings maintain concentric shaft guidance during rapid acceleration.
Mechanical reference surfaces maintain alignment after the motor is seated against the mounting face. Coaxiality between the shaft and mounting face is held to 0.08 mm, while runout is limited to 0.03 mm. The smooth shaft has a sealing ring and measures 9 mm in diameter. The enclosure is protected to IP65, allowing installation in dusty areas or locations exposed to splashing water. A RAL 9005 black varnish protects the external housing surfaces. The 58 mm flange has tolerance class N, a 63 mm hole circle, and 4.5 mm mounting holes. Its 40 mm centering collar supports accurate placement against the mating machine surface. The shaft center hole follows DIN 332-2 and accepts a DS M3 thread. The bearing arrangement supports the low-inertia rotor, while the controlled mounting tolerances keep the magnetic encoder centered during operation.
