"Can I Use a Single-Phase 200 VAC Input Motor with a Single-Phase 220 VAC Power Supply?"

  • Mr. Vex

    Ms. Ori, were you on the phone with a customer?

  • Ms. Ori

    That's right, I just received an inquiry asking, "I'm planning to use the single-phase 200V specification induction motor (4IK25GN-C) that I'm currently using in Taiwan. Is it possible to use it as is?" Mr. Vex, do you know the power supply voltage in Taiwan?

  • Mr. Vex

    What?! The power supply voltage in Taiwan? Hmmm...
    Japan has single-phase 100/200 VAC and three-phase 200 VAC, right?

  • Ms. Ori

    Yes, Japan has single-phase 100/200 VAC and three-phase 200 VAC. However, overseas voltage varies from country to country and city to city. For example, the U.S. has single-phase 115/230 VAC and three-phase 230 VAC, the EU has single-phase 230 VAC and three-phase 400 VAC, and Taiwan has single-phase 110/220 VAC and three-phase 220 VAC.

  • Mr. Vex

    Now that you mention it...Oh, that was described in the catalog, too.

  • Ms. Ori

    So what would you say in this case, Vex?

  • Mr. Vex

    Well, the permissible voltage range for motor specifications is ±10 %, so ±10 % of single-phase 200 VAC means 180-220 VAC. So if you have a single-phase 220 VAC power supply, you can use a single-phase 200 VAC motor as is!

  • Ms. Ori

    Mmm... Not exactly.
    It's true that the permissible voltage range is ±10 %, but this is a specification that accounts for voltage fluctuations when used with a single-phase 200 VAC power supply. Of course, the single-phase 220 VAC power supply itself has fluctuations, so if it fluctuates to the plus side, it will exceed 220 VAC. Therefore, it can't be used in an environment where 220 V is constantly applied or in unstable circumstances. Vex! Do you remember what happens if the supply voltage to the motor exceeds the permissible range?

  • Mr. Vex

    If it exceeds the permissible range, the temperature of the motor will rise more than normal.

  • Ms. Ori

    That's right! If that happens, that would change the characteristics of the motor, and it wouldn't be able to run continuously, which is a characteristic of induction motors. In such cases, it’s better to adjust the voltage with a transformer or introduce the World K Series, which is compatible with the power supply voltage of major countries overseas as well as in Japan.

  • Mr. Vex

    The World K Series!

  • Ms. Ori

    The World K Series is compliant with international safety standards and has an overheat protective device. So it can be used all over the world with optimal characteristics and peace of mind.

  • Mr. Vex

    Yes.
    The World K Series, which is compatible with overseas voltages, also has a lineup to comply with the RoHS Directive, and I'd like to continue to introduce products that match our customers' operating environments!

  • Ms. Ori

    More details about the RoHS Directive can be found on pages 6~7 of this New Motion, as well as in the "RoHS Directive Initiatives" section of the Oriental Motor website, so study it properly before introducing it to your customers!

  • Mr. Vex

    Yes! I’ll study right away so that I can introduce environmentally friendly products to the customers!
