Product Description:
The MSK070C-0300-NN-M1-UP1-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It delivers controlled rotary motion for automated machinery, converting drive amplifier current into repeatable torque and speed that match the command profile of a CNC, PLC, or robotics controller. Typical duties include indexing tables, gantry axes, and material-handling stations where tight positioning accuracy and rapid acceleration are required.
Heat is removed through natural convection, eliminating the need for forced-air or liquid cooling in cabinets with moderate ambient temperatures. The motor follows a standard mechanical design with a frame size of 070 and a C length code, so mounting dimensions remain consistent across comparable torque classes. Its feedback wiring exits a housing that is rotatable through 240°, which simplifies cable routing in confined enclosures. Position data travel over the Hiperface interface, and the integrated optical encoder resolves the shaft angle into 128 signal periods per mechanical turn. Because the sensing principle is optical, the feedback channel is not affected by magnetic stray fields that occur around high-current busbars.
The encoder uses multiturn absolute feedback and tracks up to 4096 shaft revolutions, enabling reliable homing after power loss without external switches. The electrically released brake supplies 23 Nm of static holding torque, allowing vertical or suspended loads to remain secured whenever the drive is disabled. Mechanical transmission is handled through a shaft with a keyway, a widely supported interface for pulleys, couplings, or gearboxes. Stator conductors follow winding code 0300, a configuration that balances current demand with voltage use in 400 V class drive systems.
