💧 Fan Mtr W/Acorn Nut Kit
Made by Nidec-Motor-Corp/US-Motors, manufacturer part number 473785. It is listed for the equipment shown below, so check the model on your own unit against that list.
✅ Listed for
- Pentair UltraTemp Heat Pump
U.S. Motors (Nidec) replacement motor – 1/3 HP, 208V–230V, single speed, 48Y frame
⚙️ What this motor is
This is a replacement motor only. It is a 48Y frame motor. It runs on 208V–230V, single speed. Check the part number against the unit you are repairing – a motor in this position is specific to the equipment it came out of.
✅ Check these before you order
- Rating. This motor is rated 1/3 HP.
- Frame size. Measure across the round body of the motor: roughly 5-1/2 to 5-7/8 inches is a 48 frame, roughly 6-1/2 to 6-3/4 inches is a 56 frame. Measuring beats reading the old label, because some makers labelled 48 frame motors as 56. This one is a 48Y frame.
- Voltage. This motor is 208V–230V. Check it against the label on the motor you are replacing before ordering.

Find the right pump or motor
Enter what is printed on the label of the one you are replacing. Anything that differs is shown with the difference spelled out, so you can judge it for yourself.
Port size is the plumbing thread, not the pipe — a 2 inch union measures about 3 inches across the male thread. Amps are compared to within half an amp, since published figures round differently between motor brands. Voltage is never treated as a near miss: a 115V motor is not one step from a 230V supply. Anything whose page does not publish a figure you entered is left out rather than offered with a caveat — search it by name to see it anyway.
