I have a Hayward super pump. Power is getting to the pump but it just makes a whining sound and then breaker trips if I leave it on too long. How can I fix it?

Likely the capacitor, the centrifigul switch or bad windings in the motor, I would start with testing the capacitor.
Where do I get parts for it? Is it better to fix or buy new? If I buy new what brand? Pool is 26700 gallons.
If it's the capacitor, that should be an easy fix. If it turns out to be the windings in the motor, you may be looking at a new motor - I would get a price for fixing vs. replacement just to have the facts, though. If you do get a new motor, I would replace it with one of the same Service Factor HP (SFHP) rating if you will be using the same pump (the wet end) with a new motor. Also, replace the shaft seal if you get a new motor.

My pump is a hayward 1.5HP pump but sounds like it's too big? Pool is 18' x 36' not including the steps (rectangle pool). Is variable or multiple speed a lot more expensive than single speed?
It is a bit big, I would suggest swapping out the single speed motor for a 2 speed, should cost under $400, maybe under $350 mail order. Best thing about swapping motors is it can usually be done without disconnecting any plumbing, only 8 bolts to deal with plus the wiring.
I tested the capacitor and tried a new one and still it's humming. What is the next thing I should test?
I need either a new motor or get a new pump. What's the better route? I have a hayward Super pump 1.5HP. Can I replace just the motor with either a 2 speed or variable speed motor? If a new pump should I get a VS or 2 speed? What I'm looking for is quiet and energy efficient. If I get a VS can I set it to the lowest speed 24/7 and will it cost less and will it cycle the water or too slow?
As said in a previous post, if you replace the motor make sure it has the same HP and SF or more. Under sizing a motor can burn out a motor. A VS is the way to go.
your first post said whining and the last one said humming. The former indicates it is running and may have a bad bearing. Humming is either a bad start cap, bad centrifugal switch on the end of the motor or a jammed up impeller. Does the impeller turn free by hand?
I'm sorry it's a humming and doesn't start. I replaced the capacitor and same issue. How do I test the centrifugal switch and what does it look like? I will see if the impeller turns freely by hand. If it does or does not what does it mean? Thank you.

If it's humming it might be jammed with debris.
remove the motor from the pump with the power off and see if you can turn the impeller.
mine hummed once during winter and somehow a clump of pine needles was the cause.
