Thanks for the initial contact Urtle.
Wow -- All info on old and replacement motor is the same unless noted below:

1) I'm not good with acronyms, what is OEM?
2) Brand is Hayward (who uses a Smith motor) and adds their "wet-end" pump.
3) HP is 1.5
4) RPM is 3450 / 1725
5) Max amps on old is 15 / 3.5 on old; 12 / 3.1 on new
I still have the original motor, the electrical contacts carbon up and
over-heat when motor is run on high. The same thing happened with the
replacement after using the spa for 1 hour. Previously the old motor was
used for as long as 3 hours at once on high and performed well for ten
years. The low speed function of the motor only comes on when the
thermostat determmines more heat is needed.

I keep replacing the 2 speed motor for the water pump on my spa, the new
ones keep over-heating. The original one lasted ten years. If I
understood
how the motor works in general, e.g. what changes to give it a higher
speed,
I might be able to figure out why I am burning up motors on high
suddenly.

Thanks in advance.


This is urtle.

The first mistake do it yourselfers make is to not use a OEM motor. If
your
going to try out Universial motors on the spa. You need to look at all
motors
and look to see that the R.P. M. , Amp draw, Horse power, Power factor ,
and
speed verses horse power matches. With all this in place you can use
universal
motors and not go back to the original OEM motor.

Now one thing in this hunt for the right motor. You need to keep the
original
motor for referrence in the future or at least keep the motor tag to use
to know
what the original OEM motor was in the futrure.

Now you ask for a website to match up the motor that you have now. State
the
brand and maybe the tag info and i can give you a website to match with.
