Frame
All industrial standard is IP21,also IP23 is an option, but rates power will decrease 5%
Marine standard alternator is IP23,Air filter is an option, but rated power of the alternator will decrease 5% while it is installed.
Axis and Key
All of alternator rotors should pass balance test, whose vibrations are lower than the minimum of BS6861 P.1,G 2.5 two bearing alternator has a half-key testing balance
Terminal and terminal box
The three-field alternator had 12 leads brought out to the terminals in the terminal box. The terminals are put on the non drive end . The box is equipped with removable panels.
Voltage regulation
Voltage regulation refers to the change of voltage from no-load to full-load with power factor ranging from 0.8 to 1 and 3%s fluctuation of the speed of engine. Voltage is adjusted via potentiometer of AVR
