Brushless Generator
A brushless alternator is composed of two alternators built end-to-end on one shaft. Smaller brushless alternators may look like one unit but the two parts are readily identifiable on the large versions. The larger of the two sections is the main alternator and the smaller one is the exciter. The exciter has stationary field coils and a rotating armature. The main alternator uses the opposite configuration with a rotating field and stationary armature. A bridge rectifier,Website:, called the rotating rectifier assembly, is mounted on the rotor. Neither brushes nor slip rings are used, which reduces the number of wearing parts. The main alternator has a rotating field as described above and a stationary armature (power generation windings).Varying the amount of current through the stationary exciter field coils varies the 3-phase output from the exciter. This output is rectified by a rotating rectifier assembly, mounted on the rotor, and the resultant DC supplies the rotating field of the main alternator and hence alternator output. The result of all this is that a small DC exciter current indirectly controls the output of the main alternator.SZN182 Brushless Synchronous AC AlternatorsVoltage:110-480VRated Power:16.8-53KVA Three-phase.H(125℃/40℃)Single-phase.H(125℃/40℃)FREQUENCY50HZ 3000rpm60HZ 3600rpm50HZ1500rpm60HZ1800rpmSTAR-SERIESSTAR-PARALLELDELTA-CONNECTIONN/AN/AN/AN/AN/AN/ASZN182HRATED CAPACITY(KVA.824.824.8RATED POWER(KW)24242426..819.819.8EFFIECIENCY82.683.183.581.681.982.482.877.277.277.97575.676.2SZN182JRATED CAPACITY(KVA)35353537.840404023.523.523.828.928.928.9RATED POWER(KW)28282830.232323218.818.818.823.123.123.1EFFIECIENCY84.184.584.883.183.483.984.278.578.579.276.577.177.6SZN182KRATED CAPACITY(KVA)37.537.537.544.346.946.946.RATED POWER(KW)30303035.437.537.537.520202024.824.824.8EFFIECIENCY84.885.285.58484.384.78580.480.480.878.879.276.6SINGLE BEARINGDIMENSIONABCDEC OF GMMSZN182H561479359.X3.0SZN182J561479359.X3.0SZN182KX3.0DOUBLE-BEARINGDIMENSIONABCDESZN182HSZN182JSZN182KCOUPLING DISCSAE NO.ANARASATV6.5#30.268.7200215.87.5#30.288.7222.2241.2862611244.5263.41053.8811295.3314.211.539.6811333.4352.3ADAPTORSAE NO.RSTUVWX21211466.715432447..615396409...322.5301314.3356ADAPTORSAE NO.RSTUWXF21211466.715447..615409...322.5314..822.5266.7358235TRANSPORTAION DATATYPEN.W(kg)G.W(kg)PACKAGE SIZE(cm)SZN182H13815585X51X58SZN182J14616485X51X58SZN182K16318185X51X58 TRANSPORTAION DATATYPEN.W(kg)G.W(kg)PACKAGE SIZE(cm)SZN182H13515276X51X58SZN182J14316176X51X58SZN182K16017876X51X58
