    Tips: What is the development prospect of permanent magnet generators?

    It has been greatly utilized in industrial and agricultural production, daily life, and national defense science and technology, and has a trend of development and growth. High-power generators are often used in luxury and ultra-luxury air-conditioned vehicles. They consume a lot of electricity at idling speed. Excitation generators can only meet this requirement by increasing the speed ratio between the driving wheel and the generator pulley. The superior low-to-medium-speed power generation performance of the machine can just solve this technical problem.

    The car air conditioner is installed on the side of the car, closer to the ground. During driving, dust and debris can easily enter the generator body, which can easily cause the contact between the excitation generator carbon brush and the slip ring to increase, thereby affecting the normal operation of the generator The permanent magnet generator has no slip ring, no carbon brush, and large air gap between the stator and rotor, which is especially suitable for working in this harsh working environment.

    Outstading alternator!
    I installed this alternator in my truck and it works perfectly. Thank you for the great price and quality product I am very happy now. If you need one, I highly recommend it. A high rating is worth.
