The stator core is built up of thin punched laminations of electrical grade steel, which are commonly called “punchings.” They are segmented, meaning that 12 to 24 punchings are laid side-by-side to form a complete 360° ring, comprising one layer.

How does a stator produce electricity?

The stator is the coil of wire housed inside the engine case. A magnet on a shaft spins within the stator, creating alternating current (AC). That current travels along fairly heavy gauge wire through the case and into the rectifier/regulator which converts it to DC power, and at a consistent output.

How is rotor made?

An alternator rotor is made up of a wire coil enveloped around an iron core. The magnetic component of the rotor is made from steel laminations to aid stamping conductor slots to specific shapes and sizes.
