Customer Reviews

greef team is the best! i love them, they give professional and timely after-service. because of my unprofessional operation, the generator went wrong, but greef team helped me to solve this issue very patiently, the generator is good now, thanks again.

—— Jeam Mareie from Canada

¡Perfecto! Ayer, recibí este generador en Bogotá, muy buen generador. ¡Gracias

—— Stephen Brinker from Colombia

I ordered 10kW 100RPM model at the year of 2017, i ordered 1kW 180rpm this year, the disc generator has small torque,it is easy to rotate,thanks Greef new energy, I hope to do more buisness with more cheaper price on the year of 2019.

Permanent magnet alternator

Permanent magnet alternators are usually used to generate electricity. The automotive alternator converted to permanent magnet type is used for household wind generators, hydroelectric power generation and self-made backup generators. Common automotive alternators use electromagnet-driven rotors to turn the alternator on and off. Permanent magnet alternators have permanent magnets instead of rotor cores wound by electromagnetic wires.

The reason why cars use an electromagnetic rotor core is because they can use it to control the output of the alternator. The use of a voltage regulator can control the voltage sent to the electromagnetic rotor core. With a permanent magnet alternator, you will not be able to control the output of the alternator, because it does not have a voltage stabilizer or solenoid winding core to control the alternator.

The control of a permanent magnet alternator is usually done by changing the speed of the alternator. With a permanent magnet alternator, the faster the alternator rotates, the more power the alternator generates.

What are the advantages of permanent magnet alternators in wind energy applications?

Direct drive (no speed increaser, no gearbox required)

No maintenance

Highest power-to-weight ratio in direct drive

high efficiency

Simplify mechanical design

Simple mechanical interface

Cost optimization

Wind turbines are usually equipped with asynchronous generators that need to double the speed of the rotor in order to generate the desired electrical power. Compared with asynchronous generators, permanent magnet alternators are very compact, and because the rotor is directly driven, mechanical integration can be simplified. The efficiency of permanent magnet synchronous alternators is higher than that of asynchronous generators.

The application of wind turbines is growing-the cost of generating 1 kW per hour of wind energy is the cheapest renewable energy source
