Gasoline generators rely on spark plugs for ignition. If AC power is supplied after the generator is connected to the circuit, the AC power and the self-prepared generator power supply will be synchronized out of synchronization, destroying the unit. This is called reverse generator power supply. Although your generator is not working, it is connected to the mains and there is electrical equipment running in the house, so the motor windings are fried.
The correct answer is that the gasoline engine can be used. The stator and rotor are just the generator part and the power part is completely separate. Have you ever seen one that sells gasoline engine power? There is also the water pump supplied with the gasoline engine. Farmers purchase a gasoline engine and add it to the thresher to thresh grain. And do you understandthis jiachenchong? The spark plug ignition coil of a gasoline generator is installed on the gasoline engine. There is a permanent magnet on the steering wheel. Rotation of the steering wheel and induction of the ignition coil generate current to the spark plug and the gasoline engine starts. Every time the steering wheel turns, the spark plug lights up. It has nothing to do with the battery. In addition, current gasoline generators under 5 kW are mainly started manually and do not have a battery.
