High Efficiency Low Rpm Speed Direct Drive Permanent Magnet Alternator Generator Price
The demands for different kinds of energy are rising rapidly. Humans are in need of electricity and other powers desperately. In order to create electricity for lighting, cooking, heating, and other uses, permanent magnet generators and other advanced equipment are developed.
Permanent magnet generators are devices that convert mechanical movements to electricity using their own magnetic fields.It’s a type of electric motor that uses permanent magnets rather than windings on its field.These devices are commonly used in wind turbines, steam turbines, gas turbines, and engines to create electrical power.
They consist of two main components: a rotor with powerful magnets and a stator with copper coils. The rotor is made from permanent magnets, and it could generate magnetic fields. Magnetic parts are set around the stators as well, so fluxes could compass them.The stator is composed of rotating coils. Once receiving the magnetic power, the stator generates electricity consequently.In this way, the movement of the rotors is transformed into electric energy. The more stator coils we have, the more electric currents we get.

Detailed Pictures
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 main components of permanent magnet generators are stators and rotors.
The rotor is made from permanent magnets, and it could generate magnetic fields. Magnetic parts are set around the stators as well, so fluxes could compass them.
The stator is composed of rotating coils. Once receiving the magnetic power, the stator generates electricity consequently.
In this way, the movement of the rotors is transformed into electric energy. The more stator coils we have, the more electric currents we get.
The permanent magnet alternator’s rotor is directly equipped with a wind turbine so that it can generate fixed electrical power. The efficiency of permanent magnet synchronous alternators is way higher than that of asynchronous generators. It offers a variety of merits over asynchronous generators and they are as follows:
· Direct drive (No speed multiplier, no gearbox needed)
· Virtually no maintenance
· Highest power-to-weight ratio in direct drive
· High efficiency
· Simplification of mechanical design · Easy mechanical interface
· Cost optimization
· They are environmentally friendly and do not rely on the external weather to produce electricity
· They are smaller in size and hence require very less space compared to other types of generators.
Advantages:
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
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.
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.
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.
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!
