Below is a list of FHP Motors manufacturers from Portland, Oregon. The term FHP motor is an abbreviation for fractional horsepower motors, which are motors that are built in a frame, traditionally with a power output of smaller than one horsepower. However, that is not necessarily a requirement of being categorized as a FHP motor, and motors can be categorized as one based on their frame size as well if the frame size is a 42, 48 or 56.
