I have recently torn down the air blower of a car (for cleaning).
I was wondering what is the name (and purpose) of the parts shown on the picture :
It looks like a copper wire wrapped around a (magnetic?) cylinder. Is it a solenoid? I don't think it's brushes (which are above head of first arrow). This is not specific to my car, I have googled for other car blower pictures and this seems to be common.
Also (another question) is there a reason for most car manufacturers to use brushed motors instead of brushless ones for air blowers? It create tons of black dust (as shown on the picture) and they wear pretty quickly.
