Product Description:

The MSK070E-0450-NN-S1-UP0-NNNN is a synchronous servomotor from Bosch Rexroth Indramat that belongs to the MSK IndraDyn S Synchronous Motors series. The unit converts drive current from an IndraDrive controller into precisely metered torque and speed for positioning tables, pick-and-place heads, and other high-cycle automation axes. Integrated position feedback allows the motor to close the servo loop directly at the shaft, giving the machine a compact actuator with simplified wiring in multi-axis systems. It is suited for applications that require repeatable acceleration, deceleration, and short indexing movements throughout continuous production.

Heat is removed solely by natural convection, so the housing relies on ambient airflow instead of forced fans. This cooling method reduces external components and keeps the motor enclosure uncomplicated. Feedback signals leave the device through a connector that is rotatable through 240°, which helps reduce cable strain during installation. Inside the encoder, an optical scanning system produces 128 signal periods per mechanical revolution, and these incremental tracks are transmitted using the Hiperface protocol. The high-resolution feedback supports smooth velocity regulation and precise position interpolation in modern digital drives.

Mechanical interfacing is handled by a shaft with a keyway, ensuring positive torque transfer to pulleys or couplings without relying on friction alone. The sensing system operates in a single-turn format, so absolute position is retained within one revolution while additional turns are counted in the drive. Electromagnetic parameters are set by winding code 0450, and the active stator stack corresponds to motor size 070 with length variant E. The motor is supplied without a holding brake, so external holding force is needed when the load must remain fixed after power is removed.
