100V motor on a pump?

    Looking at a pump, it has a 4-pin connector. It's rated for 100V, 50/60 Hz, .15/.17 A, 5W. Considering the frequency rating, it seems like this is an AC pump. Considering that the voltage is "100" rather than "115" or "120", and considering the 4-pin connector, it seems like this is a DC pump. Does anyone know what the situation is? Also, if this is an AC pump, why is it rated 100v instead of 115 or 120? The company makes other models that it lists as being 115 V. If this is an AC pump that can hook to 115 mains, what would be the disadvantage relative to using a pump rated for 115? Would it likely burn out faster? Thanks.

    Sounds like a pump made for the Japanese market......

    That explains it! It's make by Iwaki, a Japanese company. Can I run it safely and unattended on American 120 mains voltage?

    All the equipment of Japanese origin I have used generally specify ±10%.
    You could either take a chance, or use a small buck/boost transformer for that size of motor.
    If you post details of a PC might be possible to detect the nature of the motor.
    How is the connection shown for the 4 pins?
