Guericke is the standard alternator of the GTL Diesel generator, which features high efficient, strong, and durable, high electric performance. Today we will introduce the features and the difference btw Guericke, Stamford, and the other Chinese alternators from materials and manufacturing processes.

Gtl Diesel Generator

1\Raw Material


Type Guericke Stamford Other Chinese alternator
Copper wire From CITYHAMP DARTON, 100% H Class Insulation Copper Wire From CITYHAMP DARTON, 100% H Class Insulation Copper Wire Uncertain, some use Copper Clad Aluminum wire.
Lamination
steel
50WW800/ IRON LOSS 8W/TON/THICKNESS
0.5MM Silicon steel for main rotor/stator and
excitor rotor/stator
50WW800/ IRON LOSS 8W/TON/THICKNESS
0.5MM Silicon steel for main rotor/stator and
excitor rotor/stator
steel plate by 1mm thickness Steel for excitor stator/rotor, steel for below 200KW main rotor,and stator using scattered pieces
Housing for
above 200kw

- Ribs using steel bar
- dimensions control, 314 housingfor
314stator/rotor, 354 using housing for 354 stator/rotor
Same strucuture as stamford:
- Ribs using steel bar
- Dimensions control, 314 housingfor
314stator/rotor, 354 using housing for 354
stator/rotor
1.Usuing tube as ribs;
2. Ribs height is big to 314 housing with 274 stator/rotor and 354 housing use for 314 stator/rotor
Shaft Excitor and drive disc HUB is same as Stamford Redeuced excitor and hub diameter: Excitor is
special and Drive dics hub is smaller for less
torque sufferring.
AVR Use 100% KERUI AVR which had same PCB Board
as BASLER with higher stability
Basler AVR FUAN made AVR with low stability

Guericke and Stamford use high standard and quality materials which make the alternator have a longer service life, more adaptable to harsh environments(high temperature and high humidity,), and increase its stability, vibration and pressure resistance.

2\Manufacturing processes

Type Guericke Stamford Other Chinese alternator
Reduce main
stator/rotor core
length(For example @32kva
220mm 220mm 175mm,
Teminals 1. Using washer to over 2 terminal end;
2. AVR test line separated with main line;
3. Terminal ends with soldering
Terminal ends contacted without washer by bending, and no solder in.

Rotor process
control
1. Rotor wire wires is orderly rows;
2. Rotor ends with 3 layers by better heat spread
1. Rotor wire is Irregularly arranged;
2. Rotor ends is only 2 layers by saving wire

Guericke and Stamford strictly control each production process, from the material chosen, and the design is more in line with the actual demand. So that it could promise the alternator a good performance.
