130V is a bit too high.

I have never seen it at 130V however I don't think that is what burned out the pump.

Is it 220 or 260? (120 or 130)

A 260V resi pump motor?:?
No, was the voltage 220 or 260...
The poster stated the voltage was 130, but then stated the pool guy said the voltage at the pump was 220.

I think he meant the pump could be ran on either 120 or 240 (120 or 230) and the selector was set for 240 (or 230), and the receptacle for the pump was 240. In other words, the voltage rating at the receptacle was what was required by the pump at the higher voltage setting. But if he had 130V on each leg that would be 260V across the two.

130V on each leg measured how? Relative to what? Is the voltage at the service to the house phase to ground 130V off of both A and B phase?
Something is not adding up here.

POCO likely has a malfunctioning regulator on the primary side of their distribution system.
Did the motor burn up or an electronic control? The motor would likely handle 260 volts.

just the motor, basic old time clock control.

No problems with anything else? Motors are the one thing that will take this extra voltage better than many electronics procucts will.

I see 125/250 on a regular basis. 130 is pushing the upper tolerance. Light bulbs would burn out before a motor.
I also see 212-215 on a 208Y service.

Yea, +- 5% of nominal is our limit.

And I still don't understand what you mean.
The utility is running high, it happens.

I have seen voltage barely over 125V where I live, I have never seen normal voltage 130V phase to ground on both A and B. And then, why is the only thing that burnt up the motor? That would be the one thing that would survive an over voltage.
If the voltage coming into the house was 260V phase to phase to phase, 130V phase to ground, I would think something else in the house would have problems.
