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, 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-SERIES380400415416440460480220230240 220230240STAR-PARALLEL19020020 8208220230240110115120110115120DELTA-CONNECTION220230240240254266277N/ AN/AN/AN/AN/AN/ASZN182HRATED CAPACITY(KVA)3030303335353520202024.824.824.8RATED POWER(KW)24242426.428282816161619.819.819.8EFFIECIENCY82.683.183.581.6 81.982.482.877.277.277.97575.6 76.2SZN182JRATED CAPACITY(KVA)35353537.840404023.523.523.828.928.928.9RATED POWER(KW)28282830.232323218.818.818.823.123.123.1EFFIECIENCY84.184.584 .883.183.483.984.278.578.579.2 76.577.177.6SZN182KRATED CAPACITY(KVA)37.537.537.544.346.946.946.9252525313131RATED POWER(KW)30303035.437.537.537.520202024.824.824.8EFFIECIENCY84.885.285 .58484.384.78580.480.480.878.8 79.276.6SINGLE BEARINGDIMENSIONABCDEC OF GMMSZN182H561479359.52351162271X3.0SZN182J561479359.52351162271X3.0SZN 182K6015193992551162471X3.0DOU BLE-BEARINGDIMENSIONABCDESZN182H682600390265116SZN182J682600390265116S ZN182K722640430285116COUPLING DISCSAE NO.ANARASATV6.5#30.268.7200215.87.5#30.288.7222.2241.2862611244.5263.4 1053.8811295.3314.211.539.6811 333.4352.3ADAPTORSAE NO.RSTUVWX21211466.715432447.649531211428.615396409.545141211381153523 61.94035811333.322.5301314.335 6ADAPTORSAE NO.RSTUWXF21211466.715447.64892033811428.615409.5451203481138115361.94 022035811333.322.5314.33582036 811285.822.5266.7358235TRANSPORTAION DATATYPEN.W(kg)G.W(kg)PACKAGE SIZE(cm)SZN182H13815585X51X58SZN182J14616485X51X58SZN182K16318185X51X5 8 TRANSPORTAION DATATYPEN.W(kg)G.W(kg)PACKAGE SIZE(cm)SZN182H13515276X51X58SZN182J14316176X51X58SZN182K16017876X51X5 8 url: http://www.fjtjmotor.com
