Hey what are the total specs for this motor concerning the outer design and sizing?
Being a buyout item we have very limited information for this motor. If you need specific dimensions or information, you can contact our tech support and we can pull a unit from stock for further details.

I HAVE A RS-555 VC MOTOR NEEDS REPLACED. WILL THIS RS -555 PH BE A GOOD REPLACEMENT? ITS FOR A AUTOMATED SWIMMING POOL CLEANER
I do not know the difference in the two motors based upon the PH suffix, but suspect it may work. And if it doesn't, you haven't invested a lot!

What potentiometer should I use
I am looking for a potentiometor to reduce the 12vdc 3.5amp power to a variable 0-1.25 amp. Will a potentiometer do this?
You "could" control a DC motor with a variable resistor (a potentiometer). While the latter approach works well, it generates heat and hence wastes power.That being said. 12VDC @ 3.5 amps is about 42 watts.The only pot I know of that can dissapte that much power is a high power "L pad". A 50 watt should do the trick, and Parts Express has them.....BUT....As the voltage is absorbed, the motor also looses power as it slows down so you might not end up with a very useful power curve...and L pads aren't ultra cheap.A better bet?A simple pulse width modulation DC motor control eliminates these problems. It controls the motor speed by driving the motor with short pulses ...of "full" power so the strength of the motor isn't affected. Only the speed. Nice!With this kind of circuit, the pulses vary in duration to change the speed of the motor. The longer the pulses, the faster the motor turns, and vice versa....and the parts a pretty cheap.You can find examples with circuit layouts pretty much everywhere. UTube has many good videos, and of course Parts Express has the parts too.Good luck!
