Product Description:
The MSK061C-0300-NN-M1-UP1-NNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is deployed in industrial automation where precise electronic commutation and high-resolution feedback are required for packaging machinery, gantry axes, or transfer stations. The unit operates as the rotary actuator in a matched drive system, converting regulated inverter current into predictable shaft torque and motion for repetitive production cycles. Its permanent-magnet rotor and built-in position sensor allow tight velocity loops while minimizing settling time on multi-axis platforms.
The mechanical frame follows the Natural convection cooling concept, so heat dissipates across the aluminum housing without auxiliary fans. Bosch Rexroth labels this configuration with winding code 0300, which defines the stator’s electrical resistance and current density for the selected lamination stack. Geometrically, the motor belongs to motor size 061, and its active section is the length C variant, giving a compact form factor that still supports the continuous torque expected from this size class. The drive shaft is machined as a shaft with keyway, allowing direct coupling to timing pulleys or rigid hubs while preserving positive torque transmission. A rotatable 240° connector on the encoder side lets wiring exit in the preferred direction, and the overall design is listed as standard, meaning no special coatings or flange deviations are present.
For position feedback the motor uses an optical sensor that combines the Hiperface interface with multiturn absolute counting, permitting the controller to recover position after power loss without homing routines. The scale inside the encoder generates 128 signal periods per mechanical turn, and the optical technology improves edge clarity for fine velocity control at low speeds. Motion can be held safely when power is removed because an electrically-released holding brake is integrated; it delivers 10 Nm of static torque so vertical or suspended axes remain stationary during maintenance or emergency stops.
