  Alternator /peration

  0wo main parts' rotor and

stator

  0he rotor is located in the

center

  creates a rotating magnetic

+eld when turned $y the drive$elt

  0he stator is a stationary set of 

windings surrounding the rotor

  output winding in the

alternator

  hen the rotor spins' its

strong magnetic +eld cuts across

the stator windings

  Current is induced in the statorwindings
