Kirby Motor Sound

[kirbyclassiciii]

I think I understand why some Kirby motors sound the way they do: I believe the armatures used on models 505 to 518 have one fan with 6 blades and another with 14 blades, while the main impeller fan used on models 505 to 514 has 6 blades and the 515 and up has 10 blades.

It's the 14-blade secondary cooling fan that sounds the loudest.

The

Older kirbys will have slight buzzing sound from armature and older motors take a little longer to wind down. The fans move more air than and non metal fan.
The secondary fan on 4 amps are more efficient but they're pushing 4 amp motor instead of 3 amp.
