4 pole 380V 4-5.5KW frequency conversion motor and inverter about how much money, such as the use of electromagnetic speed motor comparison
5.5 inverter motor around 2000 it is almost so much money electromagnetic speed does not know that we do not produce, but now the basic are the frequency of the world
About 2,000 yuan, electromagnetic speed and vector inverter can bring feedback
4-5.5KW inverter made about 1300 or so, the frequency conversion motor about 3000
The same power of the electromagnetic governor + motor about 4000, the price is almost
