Product Description:

The MSK101C-0450-FN-M2-AG2-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit is intended for closed-loop industrial axes where rapid acceleration, precise velocity control, and accurate positioning are required. By coupling directly to machine components, it supplies commanded torque and speed with minimal compliance, making it suitable for packaging heads, robotic joints, and metal-cutting spindles. Its synchronous design also supports stable response during repeated indexing, contouring, and speed-controlled motion.

Thermal management is handled through liquid cooling, and the FN code in the type designation means an external coolant circuit must remain active for continuous rated output. An electrically released holding brake can clamp up to 70 Nm, allowing vertical loads to remain secured when the drive is disabled. Position feedback is delivered through an optical multiturn encoder that communicates via the EnDat2.1 interface and offers 2048 signal periods per revolution, supplying the controller with high-resolution absolute data across multiple turns. The rotor couples to driven equipment by a plain shaft, which suits clamp-style hubs and other friction-based connections where a keyed shaft is not required. The housing is sealed to IP65, protecting internal components against dust and low-pressure water jets during typical plant washdown.

The motor operates in ambient temperatures from 0–40 °C, which matches most enclosed machine spaces. Thermal durability is supported by insulation class 155, so winding temperature can rise above ambient without damaging the varnish system under normal operating conditions. Electrical behavior follows winding code 0450, which matches the current and voltage data used by compatible drives. The C-length housing in the 101 frame balances torque density with rotor inertia, helping the axis remain responsive during acceleration and deceleration. An increased concentricity design reduces radial runout for smoother rotation, and power and brake conductors exit on the A-side to simplify cable routing in tight assemblies.
