Product Description:

The MSK070C-0450-NN-M2-UP1-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts drive-amplifier current into controlled rotary motion for positioning and velocity loops in industrial automation cells. The unit has motor size 070 and length code C, placing it in the mid-range of the series and giving a compact housing with useful continuous torque capacity for space-limited axes.

Cooling for the motor housing relies on natural convection, so airflow around the frame is sufficient without forced fans or liquid jackets. Feedback to the drive is supplied through the EnDat2.1 digital interface, which sends high-resolution absolute position data over a bidirectional link. That position data comes from an optical measuring system with 2048 signal periods per revolution, helping the drive maintain stable commutation and smooth low-speed control. Installation flexibility is improved by an encoder connector that is rotatable through 240°, allowing the cable exit to be adjusted when clearance inside the machine frame is limited. This arrangement supports accurate axis movement without requiring extra cooling hardware.

A power-off safety function is provided by an electrically released holding brake with 23 Nm of static torque, which helps prevent unintended axis movement when power is removed. The encoder uses a multi-turn absolute arrangement, so the stored position is retained after a power cycle and a homing routine is not required at restart. Mechanical runout is reduced by the motor's increased concentricity design, which benefits applications that need tight radial accuracy on the driven load. Output torque is transmitted through a shaft with a keyway, and winding code 0450 matches the electrical characteristics expected by the designated drive type.
