In the home induction motors are used the most, because they are reliable and last a long time. They are the favoured type for refrigerators and washing machines.

The exception is portable appliances like vacuum cleaners and hand tools, which use commutator motors, basically the same as DC motors. These are preferred for their better power to weight ratio, even though they are noisy and require more maintenance such as replacement brushes and regular commutator cleaning.

Some types of electric clock use small synchronous motors that have permanent magnets built into the rotor. These motors produce only a couple of watts of mechanical power at the most.
