The rotor spins inside the alternator and is designed to create a magnetic field. The stator is essentially a box made up of many copper windings wrapped around a hollow iron core. When the rotor spins inside the stator its magnetic field rotates too and that rotation create an electrical current inside the stator’s windings.
Oct 03 2008 Upon removing the generator head cover I discovered the cooling fan had worked loose from rotor and nicked a stator wire before falling off completely. I carefully peeled back the ends of the nicked winding then solder spliced the wires back together. The generator now makes 122 VAC with a test load ancient 1200 watt waffle iron on line.

Feb 24 2012 Generator Protection. October 25 2020. February 24 2012. by Electrical4U. A generator is subjected to electrical stresses imposed on the insulation of the machine mechanical forces acting on the various parts of the machine and temperature rise. These are the main factors which make protection necessary for the generator or alternator.
Feb 24 2012 Depending upon the type of rotor used the three phase induction motor is classified as Squirrel Cage Induction Motor. Slip Ring Induction Motor or Wound Rotor Induction Motor or Phase Wound Induction Motor. The construction of stator for both the kind of three phase induction motor remains the same and is discussed in brief below.

Oct 07 2010 The rotor intersects this magnetic field as it is spun past the power winding thus inducing a voltage in the rotor winding. Once current flow is present in the rotor winding the rotor has been flashed. If flashing the field does not make the portable generators work you may have additional problems besides a lack of magnetism in the rotor.
Jun 06 2018 Conventional brushless DC motors are constructed with a permanent magnet rotor located inside a wound stator.
