The no-load voltage of the permanent magnet wind turbine will increase, but there is no current. Why

Introduction The no-load voltage of the permanent magnet wind turbine will increase, but there is no current. Why will the generator burn out? When there is no load, because there is no current, there will be no current passing through the resistor (resistance in the

The no-load voltage of the permanent magnet wind turbine will increase, but there is no current. Why

When there is no load, because there is no current, there will be no current passing through the resistor

(The resistance in the motor) causes the voltage drop (V

=

I

R

), so the voltage will be larger than that under load.

There is no current when there is no load, just like an unplugged battery. There is voltage but no current, so the motor should not burn out.

On a small wind turbine, the voltage it emits does not reach the input voltage of the rechargeable battery. Will the intermittent current be absorbed by the battery?

No, the power of household wind power is relatively small and the voltage is unstable. Batteries must be used to store more power before it can be used by household appliances. The voltage output by the battery is very stable, which can ensure the normal operation of the inverter. .

The power of floor heating for 260 square meters is about 2,000 watts, so it is difficult to rely on household wind turbines for power supply.

No. When charging the battery, the battery can only be charged if the voltage is greater than or equal to the charging voltage of the battery. When the voltage is lower than the rated input voltage, the battery cannot be charged. Just like the electrical appliance does not reach the rated voltage and cannot work properly.

Generators (English name: Generators) are mechanical devices that convert other forms of energy into electrical energy. They are driven by water turbines, steam turbines, diesel engines or other power machinery to convert water flow, air flow, fuel combustion or atomic nuclei. The energy produced by fission is converted into mechanical energy and passed 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 working principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: use appropriate magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction with each other to generate electromagnetic power and achieve the purpose of energy conversion.
