The term electric motor is so improperly used because it is too generic since there are many different types of electric motors that have widely varying characteristics so I am going to name exactly what type of motor is used in each appliance.
Kitchen Exhaust fan and bathroom exhaust fan:
Motor type: Induction
Design: Shaded Pole
Characteristics: very weak torque, only useful for its cheapness for fan use.
Dryer and washer:
Motor Type: Induction
Design: Induction start/ induction run
Characteristics: Good starting torque
Blender and Vacuum cleaner:
Motor Type: Universal brushed
Design: Brushed armature rotor with electromagnet field coils.
Characteristics: Speed is determined by voltage applied. High power in a lightweight package. Can run on AC or DC.
Air compressor
Motor Type: Induction
Design: Capacitor start/ induction run or capacitor start/ capacitor run. (2 humps on motor frame)
Characteristics: Excellent starting torque.
Battery operated shaver
Motor Type: permanent magnet DC
Design: brushed armature with permanent magnet stator.
Characteristics: fair torque. Can only run on DC. Speed is determined by voltage applied.

What about it?
The most common type of household motor is something called the "induction motor".

disc drives in computer
electric shaver
drills
certain kinds of electronic locking systems
...the list goes on and on and on
