In my bathroom I have:
-electric toothbrush
-electric shaver
-hair trimmer
All battery powered by DC motors.
In my car:
- starter motor
- power seats, windows, door locks, trunk release
- radiator fan
- heating/air conditioning fan
- tape deck, CD deck
- windshield wipers
- ABS high pressure pump
and there are probably more, all powered by DC motors.
The computer I am typing this on has
- two cooling fans
- hard drive
- CD drive
- floppy drive
all using DC motors.
The condenser and evaporator fans in my refrigerator are powered by DC motors.
The old cassette deck on my audio system has 3 motors (one for each spindle, plus the capstan).
Battery-powered drill and screwdriver in the toolbox.
I could probably go on... you get the idea. They are everywhere, certainly in battery-powered equipment but also in some appliances that plug into the wall.
We have them because they are cheap, efficient and adaptable to many different sizes and power capabilities.
