Product Description:
The MSK070C-0450-NN-M3-UP0-NNNN is a three-phase synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed to work with IndraDrive controllers, the unit supplies tightly regulated torque and position feedback to packaging lines, pick-and-place robots, and general-purpose machine tools. The motor is intended for controlled rotary motion in automated equipment where the drive must continuously correct speed and position errors. By integrating an absolute encoder, the motor provides a compact drive element for closed-loop automation. Its feedback helps the connected controller respond quickly to changing load conditions during repeated machine cycles.
It relies on natural convection for heat removal, so the housing surface must remain exposed to ambient airflow and no auxiliary fan is required. Because cooling is passive, the installation should allow free air circulation around the motor body. The rotatable encoder connector can swivel through 240°, allowing cable exits to be aligned toward the cabinet or drag chain without excessive bending. Position data travel over the Hiperface serial interface, which carries incremental and absolute information on a single pair to simplify wiring. Inside the encoder, a capacitive scanning method tracks rotor movement, and the base resolution is organized into 16 signal periods to support smooth speed feedback for vector control.
The feedback device is a multi-turn absolute model, so axis position is retained across power cycles without external batteries. Rotary power is delivered through a shaft with a keyway, enabling positive torque transfer to standard pulleys or couplings. The motor uses winding code 0450, and the physical frame size is 070. Length C identifies the housing length used for this version. The motor has no holding brake, so external holding force is required when the application must keep the load fixed at standstill.
Frequently Asked Questions about MSK070C-0450-NN-M3-UP0-NNNN:
