Is it possible to make a diesel generator from an electric motor and a diesel engine?
Hello. I have a question about the generator. I have an electric motor (4 kW, 3000 rpm, 380 V). I am not an electrician and therefore I ask: if I connect a diesel engine to it (3000 rpm) - will I get a diesel generator? I understood correctly and accordingly I will receive (4 kW, 380 V)?

In order for the electric motor to start working in the generator mode, its rotor must be rotated at a speed higher than the working one by 10%. That is, the diesel engine must rotate the rotor of the engine at a speed of not 3,000 rpm, but 3300 rpm, and the diesel engine must be of sufficient power, that is, it must produce power equivalent to more than 4 kW. And the output of such a generator will be 380 V, the power depends on the efficiency of the engine, losses, as a result, the output will be 2.8 kW at best.
