Decot 10/16 port in Perfect Pitch (Audio)

[Archon]

I sounds even better in person I was right accross the street from it. Talking on Cell phone waiting for noon to come and it goes at 11.55am I had finger in one ear and phone in other my ears did not ring tho

Perfect Pitch means it is actuly producting the hz it was supose to most sirens get close being off by a certian %

My 2T produces higher hz than normal because It gets 245Volts instead of 220 or 240 and runs around 8000rpm ( only place I ever lived that has higher voltage it usally the other way around not enough) I want to put a chopper Transformer in line and bring it down to 200 volts one day.

Oh. Thanks.

If three-phase, the rpm should be determined by the 60Hz - not the voltage.
Even if determined by voltage, 245V, instead of 208-240 three-phase, or 240 single-phase, should not cause it to be 8k rpm.
Do you have a different kind of motor?
Are you concerned the rotor may fly apart at 8k instead of 3450 rpm, typical for Federal Signal motors?
I don't know of any common motor designed to operate on 200 Volts.
I would expect them to be designed for what is found in the field: 120, 240 single-phase or 208-240, 480 three-phase.

All model 2's are single phase universal type AC/DC motors. Their speed at 240vac is over 7000rpm (whatever speed 5 ports produces 533Hz) and the speed can be adjusted by voltage just like the thunderbolt chopper.

I don't know of any common motor designed to operate on 200 Volts.

Japan runs on 100/200vac. Many motors are designed to run on 190-208vac in this range. Even a 208-240vac motor would be fine.
