Electrical insulating paper is a special insulating material used to provide electrical insulation protection in electrical equipment and circuits.
Switched Reluctance Motor Magnets
In automotive fan motors, the slot commutator is a relatively common commutator type. It consists of a fixed conductive ring and a number of brushes, usually placed at regular intervals in slots on the motor's stator.
The electrical conductivity of graphite is very good, surpassing many metals and hundreds of times that of non-metals, so it is manufactured into conductive parts such as electrodes and carbon brushes;
