Product Description:

The MSK070E-0300-NN-M3-UG1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion tasks where precise speed and position control are required, such as indexing tables, packaging axes, and material-handling stations. By combining permanent-magnet excitation with an integrated feedback device, the motor converts electrical energy from a Rexroth drive into accurately metered mechanical torque that can be synchronized with PLC command profiles in industrial automation lines.

Thermal management is handled by natural convection, meaning heat leaves the stator stack through the housing fins without auxiliary blowers, which simplifies cabinet ventilation. The encoder connector is rotatable through 240°, so the cable can exit in several directions to accommodate tight wiring spaces. Communication with the drive controller occurs over the Hiperface protocol, allowing electronic data exchange and real-time position streaming over a two-wire pair. Rotor position is interpolated across 16 signal periods, providing fine angular resolution for smooth velocity loops. A capacitive scanning principle inside the feedback unit resists contamination from oil mist or magnetic debris. The motor follows a standard design variant, has frame size 070, and uses the E-length stator stack.

The feedback device uses multiturn absolute tracking, eliminating homing cycles after power loss. An electrically released brake supplies 23 Nm of holding torque, keeping vertical or suspended loads stationary when the drive is disabled. Output is delivered through a plain shaft, allowing direct coupling through clamping hubs or shrink discs without additional gearing. Winding code 0300 identifies the electrical resistance and inductance values used with this model.
