Horsepower power ratings expalined
If the rating plate is clearly marked 1.25 it means what it says, one and one quarter horsepower. That is not a standard motor that you can easily buy, but it may be available as a replacement part or you can replace it with a 1.5 Hp motor. If you think that the marking is wrong, look at the physical size of the motor. A 1/25 Hp motor will fit in the palm of your hand and will have a shaft that is in the neighborhood of 1/8 inch in diameter.
