Stator
The stationary part of an electric motor that contains the coils of wire.
Rotor
The rotating part of an electric motor that is connected to the shaft.
Coils
Wires wound around the stator that create a magnetic field when an electric current passes through them.
Magnets
Permanent magnets or electromagnets that generate a magnetic field to interact with the stator's magnetic field.
Brushes
Conductive contacts that deliver electric current to the rotor.
Commutator
A split ring that reverses the direction of the current flowing through the rotor's coils.

Fleming's Left-Hand Rule
The rule followed by electric motors, where a current-carrying conductor experiences a force when it is kept in a magnetic field.
Fleming's Right-Hand Rule
The rule followed by electric generators, based on electromagnetic induction.
Driving Force for Shaft (Motor)
The shaft of an electric motor is driven by a magnetic force developed between the armature and field.
Driving Force for Shaft (Generator)
The shaft of an electric generator is connected to the rotor and driven by a mechanical force.
Current Usage (Motor)
