1. generators of marine motors should be able to operate continuously under full load under the following conditions;

　　The ambient temperature (air) is less than 40 degrees, and the ventilation is good.

　　2, electrical performance of marine motor:

　　(1) the steady state voltage regulation rate is less than 1%;

　　(2) transient voltage regulation rate +20%, - 15% (60%In, COSO = 0.4 lag)

　　(3) no load voltage regulation range (90%-110%) Un

　　(4) the sinusoidal distortion rate of the voltage waveform of the no-load line is less than 5%

　　(5) direct starting no load three phase quadrupole squirrel cage motor meets the following table:
