As the generator continues to run it will create a Generator Parts; Onan ; Voltage Regulators ; Volt. Here are some reasons why a self-excited generator loses its residual magnetism and fails to generate power even when running. If the generator fails to work, you should increase the voltage buildup. Instead, the magnetic field is formed by converting a portion of the generator output voltage to DC and feeding it into a coil to create an electromagnet. 7 Reasons Why Generator Not Producing Electricity. Even a tiny amount of this residual magnetism can generate a small portion of electricity. This residual magnetic field of the main poles, induced electromotive force in the stator coils, which produces initial current in the field windings. A car battery will do just fine, especially for a small generator. This residual magnetic field of the main poles, induced electromotive force in the stator coils, which produces initial current in the field windings. A 94 inches fan rotating at 4,000 rpm has a tip speed of almost exactly 500 m/s which is Mach 1.5 to 1.65 depending on altitude (Mach 1 speed varies according to air density). If the generator has been sitting, un 6 months, or longer it may have lost its residual used, for 3 magnetic field required to build voltage.
