    • High standard, quality components for use in harsh and extreme environments for wind turbines.
    • High efficiency and Low mechanical resistance energy loss.
    • Excellent heat dissipation due to the Aluminium alloy outer frame and special internal structure.
    • High strength from the specially desy selecign structure and fully heat treatment aluminium.
    • Generator is designed using speciallted material and treated to resist corrosion and oxidation.
    • Designed for reliable and long operational lifetime under long-term full output.

    Tips: How does the permanent magnet generator achieve voltage regulation?

    The principle of voltage regulation of permanent magnet generator: keep the output voltage of the generator stable by changing the conduction angle of the thyristor.

    When the rotor of the generator rotates, the magnetic field generated by the permanent magnet on the rotor of the motor cuts the stator winding and induces an alternating current potential. After being rectified by the rectifier bridge, a voltage is generated, and the power supply device is operated. The voltage regulating device changes according to the voltage of the generator. The thyristor conduction angle keeps the generator output voltage stable.
