1)Any permanent magnetic generators, providing invariable excitation on all occasions.
2)Easy to be connected with power network or other generators. Standard 2/3 pitch windings check excessive midline  current.
3)Balanced rotor with single or two sealed ball bearings
4)Convenient installation and maintenance with easy access to terminals, rotating diodes and coupling bolts
5)Wide range of Flange adaptor and single bearing coupling disc

Meet leading standards




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




Insulation Class H

All regulatory components are made up with special materials and are immersed in lacquer by peculiar tech. Vanish and colophony materials are develop to strengthen the processing and machinery intensity of windings and revolving parts for protecting the alternator work under corrosive environment.

Winding and electric features:

2/3 pith winding design can effectively eliminate the third harmonic wave(3th.9th,15th) of the voltage ,which is the best design of UPS for nonlinear load .Connected with the network in parallel, the structure can restrain excessive currents in the midline

A continuous damp windings abates surges. The poles and gears of the windings are carefully chosen, this and the 2/3 pitch help to check the wave distortion and output voltage.

Phone interference

THF(defined by 40thpart of BS4999) <2%.TIF(defined by ASAC50.12)<50

Radio interference

Brushless apparatus and quality AVR ensure little radio interference in transmission. RFI noise filter is also available.

3. IP23 enclosure

4. Space heaters

6. Thermistors


Quality Assurance


Factory Inspection, the test items before delivery are mainly as follows:


1. Each genset shall be put into commission more than 4 hours totally.


They are tested on idle load, fully load and 10% overload


2. The noise level is tested


3. All of the meters on the control panel shall be tested


4. The appearance of the genset and all of the label and nameplate shall be checked


Warranty policy


Guarantee for one year or 1200 hours whichever reach first from ex-factory date. During the guarantee period, WERNA will provide the free easy-damageable spare parts of alternator caused by our quality of production or raw material. After expiration,WERNA provides cost spare parts maintenance of alternator.
