WebThe electric motor. Electric motors are found in many household devices e.g. tumble dryers, washing machines, vacuum cleaners, electric knives, food mixers, hair dryers and electric toothbrushes. WebWhen the motor is powered by DC current, a magnetic field is created within the stator, attracting and repelling the magnets on the rotor. This causes the rotor to start rotating. To keep the rotor rotating, the motor has a commutator. When the rotor aligns with the magnetic field, it would stop spinning, but in this case the commutator would ...

A commutator consists of a set of contact bars fixed to the rotating shaft of a machine, and connected to the armature windings.
