    • Gearless, direct drive, low RPM permanent magnet generator.
    • Low start up speed due to low cogging and resistive torque design.
    • 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: Is the permanent magnet generator a DC generator or an alternator?

    The permanent magnet motor is an alternator. A synchronous motor that generates a synchronous rotating magnetic field by permanent magnet excitation, a permanent magnet acts as a rotor to generate a rotating magnetic field, and a three-phase stator winding passes through an armature reaction under a rotating magnetic field to induce a three-phase symmetrical current. Compared with electric excitation motors, permanent magnet motors, especially rare earth permanent magnet motors, have a simple structure and reliable operation; small size, light weight, low loss, high efficiency; the shape and size of the motor can be flexible and diverse, so the application The scope is extremely wide, covering almost all areas of aerospace, defense, industrial and agricultural production and daily life.

    Existing reviews of 300W 12v/24v/48v Alternator, 3 Phase
    Build quality is excellent.
    The 3-phase design allows for smooth and stable power output, even under heavy loads. I've been using it for two weeks and it has exceeded my expectations. Highly recommend.

    Works Great!
    Installed 300w alternator yesterday. Everything seems to be okay, it was a perfect fit! Works like it should. Thanks for such fast efficient delivery with roads slick in heavy ice conditions, exactly what I needed.
