DC Motors -- principles of operation

Every DC motor has six basic parts -- axle, rotor (a.k.a., armature), stator, commutator, field magnet(s), and brushes. In most common DC motors (and all that BEAMers will see), the external magnetic field is produced by high-strength permanent magnets 1. The stator is the stationary part of the motor -- this includes the motor casing, as well ...
