Andris, I’m also interested in how the “new” gasifier will work, yesterday I didn’t manage to connect everything so that I could start it today, well, it will be ready soon.
Regarding the use of an asynchronous motor as a generator, I can say the following:
- use a two-pole motor, the one that has 2900 rpm. , due to its high rotation speed, it needs a weaker magnetic field to induce voltage
- an electric motor connected in a delta and capacitors in a star enable the generation of a single-phase voltage from the star point
- if it is a 3f motor, 5kW needs 3x50 microfarad capacitors for excitation, 7.5 kW 3x 75 microfarads, etc., multiply the power of the electric motor by 10
- the voltage is not stabilized, but changes with the load, which is not disturbing for heavy consumers
- inverter welding machine, tools with brush motors, heaters, (consumers that do not cause much reactive energy) work very well, while induction motors (asynchronous) work worse (they need additional capacitors to compensate for reactive energy)
- interesting power supply of single-phase consumers, here we can load one phase with more than half of the rated power of the motor ( 5kW - it can supply a consumer with more than 2.5kW of power), the currents flowing in the delta connection add up and charge the capacitors
- if I add a hybrid solar inverter and batteries, this is an ideal and indestructible generator that can operate continuously all year round,…
