ACA Hurricane- Alert, Attack, and Growl + Pics Added

[500 AT fan]

The chopper motor is single phase, 2 HP.

lots of sirens have aluminum choppers.

All of ACA's rotors are tenzaloy alloy, to keep up better at high speed.

here are the manuals for the Hurricane that DjT1003 posted some time ago, if you didn't get them then:

Going by this it looks like the chopper motor is actually supposed to be 230/240 volts.

Thats if you want to wire the chopper and rotator up to each other. I am later going to try to split apart the two neutral wires and see if I can make this all 120V.

Matt, hooking 120 on each side means that it is a 240 motor.

That may explain it's slower than expected wind-up. I thought it would only take a half second for it to wind up, since that's all it takes with the blower running.

It doesn't soundas loud as a Thunderbolt chopper, but that could just be the mic it was recorded with.

Congratulations on that working Hurricane!

Actually I got the voltage on the "240" plug. One hot is 120V the other is 120V. the rotator hooks up to one 120V and neutral and the chopper hook up to the other separate hot and then the neutral. They are 120V each. There are two hots and two neutrals and the neutrals are wired together. The reason the windup is not fast is because there is no blower.

right, because residences get split-single-phase power. One of the 120V feeds is 180? out of phase with the other; if you measure from either hot to neutral you read 120V, if you read across both hots you get 240.

Yeah, the blower has one hell of an effect. Those choppers are light, and with the low drag of the 1 or 3 phase (doesn't matter for drag purposes) motor, and the angled chopper blades, it manages to blow the rotors around pretty well. That blower motor is HUGE! I don't know how you're planning on powering it!
