Alternate name for the cooling fins on cast rotor AC Induction rotors 1

[Clyde38]

Sorry my memory doesn't seem to be as sharp as it used to be. I find myself making more notes these days. I'm trying to remember the name used for the cooling fins on cast rotor AC Induction motors. I know it . . . I knew it . . .

Any help is appreciated. Of course you can tell that this is not a matter of life and death. It just bugs me when I can't remember something.

"Electric Motors and Drives" by Austin Hughes simply calls them blades, for air circulation. I would avoid calling them cooling fins, because the cooling (especially on a TEFC motor) comes from the external fan, not from the fins inside, which are only capable of circulating the air that is trapped inside the housing.

Thanks SparWeb, but blades is not the word I'm looking for. It is actually kind of a peculiar word (if I remember correctly) and it may be more of a European term. I will mention, that in a OPSB (Open - Slotted Band) motor, these fins provide a fair amount of air movement over the end turns.

But I appreciate the reply. I'll keep trying . . .

Wafters! Yes Pete. Thanks

Threads like this one makes an old engineer, as I am, rewind the tape.
Clyde and Electricpete, thanks.

I thought I had been in the motor business long enough not to learn anything new. But WAFTERS is new to me.
The Swedish word is "rotorvingar".
