Operation principle of the present utility model is: Rare Earth Permanent Magnet Synchronous Generator electromotor drive operating after, rare earth permanent magnet
The N of body rotor, S, N, S, 4 the most constantly setting up magnetic field, continuous cutting magnetic line, the output voltage of electromotor is when extremely short
In be exceedingly fast set up, after generator speed reaches rated speed, its field voltage has just reached default running voltage,
Now access inductive load, there is no the conversion accessories such as the carbon brush of electric excitation generator, slip ring, diode due to it, between decreasing
Connecing loss, its delivery efficiency is higher, is lost less, compressor or air compressor machine is started up in the extremely short time and works.
Relative to refrigerator car tradition electric excitation type synchronous generator, Rare Earth Permanent Magnet Synchronous Generator of the present utility model is more
Add energy-conservation, start inductive load and during linear load, voltage faster response, change in pressure drop is less, its internal non-carbonate, slip ring,
The rapid wear accessory of the conventional electric generators such as diode, cowling panel, decreases indirect waste, with under power, volume is less, weight more
Gently, delivery efficiency is higher, loss is less；
Housing is formed in one formula aluminium alloy structure, and the end cap at two ends uses the all-sealed structure of waterproof and dustproof, and it is waterproof
Grade reaches IP57, efficiently solves refrigerator car generator operation integrity problem, dustproof and waterproof, and design service life is up to 10
As long as Nian.
