It cannot be changed unless you have extremely strong practical skills. Remove the enameled wire from the secondary output coil of the toroidal transformer, bend the wire in half, then in half again, so that all four strands are wound. return to the transformer to obtain the necessary voltage at the output of the 12v charger (usually you have to add a few extra turns). After winding, the transformer must be dipped in varnish, dried and insulated.
Once the transformation of the transformer is completed, the load circuit must be modified. You can simply use the 30a output bridge rectifier to connect the transformer output to charge the 12v battery.
You should always purchase an electronic switching power supply lead acid charger of 5 A (charging a 20 to 40 Ah battery) or 10 A (charging a 70 Ah to 100 Ah battery). Ah) for tens of dollars
No. Thatr Once the generator is designed and manufactured, the magnetic field and coils are fixed, and the speed is also fixed.
A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by water turbine, steam turbine, diesel engine or other electric machines to convert the energy generated by water flow, air. flow, fuel combustion or atomic nuclear fission in Mechanical energy is transmitted to the generator, which is then converted into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life.
Generators come in many forms, but their operating principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is as follows : use suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction with each other to generate electromagnetic energy and achieve the goal of energy conversion.
