40kw 45kw 48kw 60kva Brushless Stamford AC Alternators
| ELEPHANT BRUSHLESS SYNCHRONOUS AC ALTERNATOR |
|
| Single-bearing and double-bearing type alternators are provided. The installment dimensions are standard, easy to assemble with all kinds of engines. Standard SAE interface with multi-specification can be flexibly interchangeable. Air gap between the stator and rotor core is small , therefore the alternators have high efficiency. |
|
| Excitation stator lamination is made by cold-rolled silicon steel sheet, with one or two high performance NdFeB magnets, so the temperature rising of exciter is low , it will not lose excitation. |
|
| Reliable automatic voltge regulators(AVR) provide consistent excitation on all occasions. Standard AVR:SX400;SX460,OptionAVR:MX321;MX341. |
|
| All alternator rotors are dynamically balanced to be better than miminum vibration of BS6861:part 1 grade 2.5. |
|
| Double-bearing alternators are balanced with half keys. |
|

|
| MAIN PERFORMANCE |
|
| 1.All raw materials are insulated to class H |
|
| 2.The standard protection is IP22 (IP23 is optional) |
|
| 3.2/3 pitch winding design adopted, that can effectively suppress the third harmonic wave(3rd,9th,15th,etc.).And the design avoids excessive neutral currents result from higher winding pitches , and a fully consecutive damper winding reduce oscillations during paralleling. The 2/3 pitch windings are carefully pole, and tooth ensures very low wave from distortion. |
|
| 4.Steady-state voltage regulation rate ≤1% |
|
| 5.Total harmonic distortion of output voltage(THD)≤3% |
|
| 6.Telephone interference factor(TIF)≤50 |
|
| 7.Telephone harmonic factor(THF)≤2% |
|
| |
|
| OPERATION ENVIRONMET |
|
| In the following environmental conditions , the alternators can be in the rated |
|
| operation |
|
| 1.Altitude:no more than 1000 meters |
|
| 2.Ambienr temperature:-15ºC-40ºC |
|
| 3.Relative humidity:no more than 90% |
