Product Description:

The MSK070E-0450-NN-M1-UG1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and supplied in the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop control of rotary axes in packaging, assembly, and semiconductor equipment where consistent torque and high feedback resolution are required for repeatable motion. The motor uses a standard mechanical design with an E-length stator, which supports midrange load requirements without increasing machine depth. This housing format suits machines that need more torque capacity than shorter versions while keeping the same general mounting style.

Thermal management is provided by natural convection, so heat is removed through the housing without fans or external coolant circuits. A rotatable 240° encoder connector supports flexible cable routing while preserving the sealing surfaces at the connection point. Position data travel over the Hiperface interface, and the encoder delivers 128 signal periods per revolution. Its optical scanning principle helps reduce electrical noise, while the multiturn absolute function stores shaft revolutions for position reporting after power is restored. Motion can be held during downtime by an electrically released holding brake with 23 Nm of static torque, which is useful on vertical or suspended axes.

This configuration uses a plain shaft, allowing direct coupling to keyed or clamped hubs while reducing backlash from added transmission parts. The motor has a frame size of 070, which places it in the corresponding stator diameter class and keeps mounting dimensions consistent for that size. Internal winding code 0450 indicates the electrical characteristics used with compatible Rexroth drive controllers. These values support the motor’s current response and help the drive maintain accurate speed and position control during continuous operation.
