Product Description:
The MSK070C-0300-NN-M2-UP1-RNNN synchronous servo motor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It combines a 070 frame, C-length housing, and 0300 winding to provide controlled torque in industrial automation equipment. When connected to a compatible IndraDrive controller, the motor converts regulated current into repeatable rotary motion for indexing tables, feeders, and compact gantry axes. This makes it suitable for packaging, handling, and assembly systems that depend on predictable acceleration and repeatable stopping points.
Heat from copper losses is removed by natural convection, so no external blower or liquid circuit is required. To reduce radial runout, the rotor uses an increased concentricity design that supports smooth rotation and stable speed control. Feedback is supplied by an optical encoder with a connector that is rotatable through 240°, which helps route cables in tight cabinets. The encoder communicates over EnDat 2.1 and provides 2048 signal periods per revolution for accurate position acquisition. This feedback arrangement supports precise commutation and stable position tracking during low-speed and dynamic moves. An internal temperature model works with the motor's Class 155 insulation, and the unit is intended for ambient temperatures from 0 to 40 °C.
For position retention across power cycles, the feedback system uses multi-turn absolute measurement so the controller can retain revolution information after shutdown. An electrically released holding brake provides 23 Nm of static torque to help prevent axis drift when power is removed. The brake is helpful on vertical or suspended loads where the axis must remain stationary during controlled stops or power loss. The housing is sealed to IP65 to resist dust and low-pressure water jets, and the output uses a shaft with a keyway for direct connection to standard couplings and hubs. A shaft seal is also fitted, which helps protect the bearing area from contamination during routine machine operation.
