Overview

The 4IK25RGN-C is designed for applications requiring adjustable motor speed in a compact 80 × 80 mm frame. When paired with a US-52 speed controller, it provides a speed control range of 90–1250 rpm at 50Hz and 90–1550 rpm at 60Hz.

Fixed-speed induction versions are also available, including the 4IK25GN-C for single-phase 220V and the 4IK25GN-Y for three-phase 220V / 380V applications. Round-shaft versions are available for applications where a gearhead is not required.
