Operation process

  • The magnetic field produced by the stator poles induces a voltage in the rotor (or armature) coils when the generator is rotated.

  • This induced voltage is represented by a voltage source.

  • The stator coil has resistance, which is connected in series.

  • The pole flux is produced by the DC excitation/field current, which is magnetically coupled to the rotor

  • The field circuit has resistance and a source

  • The voltage drop on the brushes represented by a battery

The induced voltage is connected to the generator terminals through the commutator and brushes

Safety

1.size

2. circuit breaker

3. qualified electrical contractor

4. NEVER store a generator near a gas water heater or furnace

5.  NEVER fuel an electric generator when the generator is running

6. ALWAYS insure proper ventillation

7.remmember Many engine parts are very HOT during operation
