It cannot be driven. The inverter is designed for three-phase motors *1
. Single-phase motors have a different operating principle than three-phase motors and use capacitors. If a single-phase motor is connected to the secondary side (output side) of the inverter, harmonic components may cause the capacitor to overheat or break. For
details on the differences in operating principles, please see the e-learning "AC Motor Fundamentals."
Please see the table below for three-phase motors *2 that can be driven by inverters .
| series | Setting frequency |
|---|---|
| Three-phase high-efficiency induction motor KIIS series |
3 to 120Hz *3 |
| KⅡ series World K series K series V series FPW series BH series |
6.6 to 80Hz |
*1Please check the voltage specifications (single phase, three phase, etc.) on the website or on the actual product nameplate.*2Increased safety explosion-proof motors and 2-pole high-speed types cannot be used even with three-phase motors.*3Only the right-angle shaft hollow JH gear has a different upper limit. 30W: 100Hz, 40W: 80Hz (reduction ratio 10 is 60Hz)
Note:
If you are using a three-phase motor with an electromagnetic brake, connect the electromagnetic brake lead wires to the primary side (commercial power supply) of the inverter. The voltage on the secondary side (output side) changes depending on the inverter settings, so the electromagnetic brake may not operate correctly.
Also, when stopping with the electromagnetic brake, do so at 60Hz (1800r/min) or less.
