Overview

The 5IK120RGN-CF is designed for industrial applications requiring adjustable motor speed in a compact 90 × 90 mm frame. When paired with a 5GN series gearhead and US-52 speed controller, it provides a speed control range of 90–1300 rpm at 50Hz and 90–1600 rpm at 60Hz. The 5GN50KB configuration shown on this page uses a 50:1 reduction ratio for stable low-speed operation.

Fixed-speed induction versions are also available, including the 5IK120GN-CF for single-phase 220V and the 5IK120GN-YF for three-phase 220V / 380V applications. Round-shaft versions include the 5IK120A-CF fixed-speed model, 5IK120RA-CF variable-speed model and 5IK120A-YF three-phase model.
