Product Description:
The MSK070D-0300-NN-M3-UP1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It provides closed-loop rotary actuation in industrial automation lines where accurate position control, repeatable torque delivery, and stable speed regulation are required. An integrated multiturn absolute encoder supplies position data to the drive, and an electrically released holding brake helps keep the axis secure when power is removed or a controlled stop is commanded.
Cooling is handled by natural convection, so the motor needs open airflow around the housing instead of external fans. The enclosure has an IP65 rating, which keeps out dust and resists water jets in demanding machine areas. Position feedback comes from a capacitive encoder with 16 signal periods, and its Hiperface interface sends rotor position information directly to the drive controller for continuous closed-loop operation. A maximum speed of 4900 rpm supports high-speed duty, while the electrically released brake can apply 23 Nm of holding torque when the axis must remain stationary. The keyed shaft, standard housing design, and rotatable encoder connector help the motor fit compact machine layouts with fewer cable-routing conflicts.
Rotor inertia of 0.00375 kg·m² supports quick acceleration and deceleration without placing unnecessary demand on the drive current loop. The winding inductance of 6.0 mH helps moderate current rise and contributes to smooth torque production during changing load conditions. Thermal insulation is rated to class 155, and the motor reaches temperature equilibrium after a 23.0-minute thermal time constant, which helps thermal behavior remain consistent during extended running periods. Frame size 070 with D length keeps the package compact, and the encoder connector can rotate through 240° to improve cable exit direction in tight enclosures.
