Product Description:
The MSK101E-0300-FN-M1-RG2-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor serves as the rotary axis element in industrial automation, translating drive current into precise torque and speed for packaging units, metal-cutting spindles, and handling robots. In closed-loop motion systems, the combination of a plain output shaft and optical feedback supports accurate acceleration, stable speed control, and repeatable positioning. Integrated cooling passages help stabilize stator temperature during continuous operation, and the housing follows the standard MSK frame profile for use in compatible machine layouts.
Liquid circulation through the FN jacket provides liquid cooling, and the motor requires connection to an external chiller loop before operation. This cooling method removes heat continuously from the housing jacket instead of relying on ambient air alone. Frame size 101 and length code E indicate the motor's torque capacity within this housing size. The electrically released brake delivers 70 Nm, permitting static load holding during power-off events. Motion feedback comes from an optical encoder that uses the Hiperface interface, and it provides 128 signal periods per mechanical revolution for closed-loop accuracy. The housing has a protection rating of IP65, and the class 155 insulation system supports elevated winding temperatures during demanding duty cycles.
The permitted ambient range is 0 to 40 °C, which suits typical plant environments and supports operation under normal indoor conditions. A right-side power connector aligns the motor cable with drag-chain layouts and helps keep routing consistent in moving axes. That connector placement can also reduce sharp bends near the housing when the axis travels repeatedly. The encoder stores position in a multi-turn absolute format, so the axis can retain turn information after restarts without a full homing cycle. The motor uses winding code 0300 for its electrical configuration.
