Product Description:

The MSK070E-0300-NN-M1-UG0-NNNN synchronous servo motor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is supplied in a standard housing and serves as a compact torque source for positioning and velocity control in automated machinery. When paired with an IndraDrive controller, the motor closes the loop through its integrated encoder so linear or rotary axes reach commanded setpoints quickly and repeatably, supporting pick-and-place, packaging, and material-handling tasks across industrial automation cells.

The stator windings dissipate heat through natural convection, eliminating external blowers and reducing maintenance. Feedback wiring enters through a side connector that is rotatable through 240°, allowing cable routing to match panel layouts while keeping bend radii within the allowed range. Position data leave the encoder over the Hiperface bidirectional interface, giving the drive both absolute position at power-up and incremental counts during motion. The measurement grid is subdivided into 128 signal periods, and internal interpolation provides fine angular resolution for smooth speed control. Sensing is based on an optical scanning principle, so the absolute scale on the code disk is read without physical contact and is immune to magnetic stray fields. The winding code 0300 identifies the electrical resistance and inductance values expected by the drive, and the natural-cooling layout supports continuous operation within the motor's thermal class when ambient temperature remains within cabinet limits.

The encoder stores position over power cycles by means of a multi-turn absolute count system, removing the need for homing after shutdowns. The unit is supplied without a holding brake, so applications that require static load retention must rely on external braking or drive torque. Frame code 070 sets the flange and stator diameter, while the E length extends the active iron stack for higher continuous torque than shorter motor lengths. A plain shaft simplifies coupling to gearboxes or pulleys because no keyway machining is required, and the balanced rotor helps reduce vibration at top speed.
