Theory of Procedure[edit]

STATOR: It fits concerning the two halves on the alternator While using the rotor spinning in the middle of it. The stator has a number of poles wound with copper wire. The poles are in groups of 3, supplying three period recent.

may be the rotational velocity in revolutions for each minute (RPM). Incredibly old descriptions of alternating present methods often provide the frequency with regard to alternations per minute, counting Every single 50 %-cycle as just one alternation; so 12,000 alternations per minute corresponds to 100 Hz.
