Low Rpm High Frequency High Output Magnetic Field Permanent Magnet Generators

The situation of waning fossil fuel supply and the critical environment state is making it more and more necessary to find alternative energy sources. More and more people are choosing permanent magnetic generators to replace traditional generators in some applications.

Compared with conventional generators, reducing other rotating parts such as gear, it is a safer option. Simplicity makes the maintenance easier, Reduce energy consumption, save power up to 40%, IE4 standard

(1) Free Energy Source
Permanent magnet generators generate electricity with the inside magnets that can be used to power other electric devices, which means that you will no longer need to pay for the expensive electric bills. In addition, you can even sell your excessive electricity to local utilities and get payment from them.

(2) Low Installation Fee
Compared to generators powered by other renewable and green energy, solar energy and wind power, for example, permanent magnetic generators are working independently of factors inside or outside of your house. You will no longer need to worry about the weather.

(3) Reliable Energy Output
A permanent magnet generator will not cost you a lot of money to install. You only need to buy everything necessary in a hardware store with little money and assemble one by yourself. With only hundreds of dollars, in one day, or less time, you can have your own permanent magnet generators at home.

(4) Maintenance Free
Another great thing about permanent magnet generators is that you do not need to spend a lot of time and money on the maintenance work. Just install it and wait there expecting it to make money for you!

What is the permanent magnet generator?

The permanent magnet generator is a device that converts mechanical energy to electrical energy. In this device, the rotor windings have been replaced with permanent magnets. Permanent magnet generators are used mostly in industrial applications like turbines and engines to produce commercial electrical energy, the permanent magnet alternator is an alternate source of energy and has multiple benefits which make it a great device for a variety of residential, commercial, and industrial applications.

The structure

The permanent magnet generator is mainly composed of a rotor, end cover, and stator. The structure of the stator is very similar to that of an ordinary alternator. The biggest difference between the structure of the rotor and the alternator is that there are high-quality According to the position of the permanent magnet on the rotor, the permanent magnet generator is usually divided into a surface rotor structure and a built-in rotor structure.

Working Principle

The permanent magnet generator uses the principle of electromagnetic induction in that the wire cuts the magnetic field line to induce an electric potential and converts the mechanical energy of the prime mover into electrical energy output. It consists of two parts, the stator, and the rotor. The stator is the armature that generates the electricity and the rotor is the magnetic pole. The stator is composed of an armature iron core, uniformly discharged three-phase winding, machine base, and end cover.

The rotor is usually a hidden pole type, which is composed of excitation winding, iron core and shaft, guard ring, center ring, and so on.

The excitation winding of the rotor is fed with DC current to generate a magnetic field close to the sinusoidal distribution (called the rotor magnetic field), and its effective excitation flux intersects with the stationary armature winding. When the rotor rotates, the rotor's magnetic field rotates together with it. Every time a revolution is made, the magnetic lines of force cut each phase winding of the stator in sequence, and a three-phase AC potential is induced in the three-phase stator winding.

When the pm generator is running with a symmetrical load, the three-phase armature current synthesizes to generate a rotating magnetic field with synchronous speed. The stator and rotor fields interact to generate braking torque. The mechanical torque input from the turbine overcomes the braking torque and works.

Disadvantages

While permanent magnet generators offer several benefits, they also have limitations that need to be considered. One significant drawback is their relatively low power output compared to conventional generators. Magnetic generators are best suited for small-scale applications such as powering individual homes or specific appliances.

Moreover, the initial cost of installing a magnetic generator can be higher than setting up traditional power sources. However, it is worth noting that over time, the operational costs of a magnetic generator can be significantly lower due to the absence of fuel expenses.Another consideration is the availability of suitable motion sources for continuous rotation of the rotor in magnetic generators. In some areas, finding consistent wind or water flow may pose challenges, limiting the feasibility of using these devices as primary power sources.

In conclusion, while magnetic generators offer numerous advantages such as sustainability and efficiency, they are not without limitations. When comparing them to traditional power sources like fossil fuels and renewable energy options such as solar and wind power, it becomes clear that magnetic generators excel in certain areas but may not be suitable for all applications. As technology continues to advance and overcome existing limitations, magnetic generators hold great promise for a greener future in energy production.
