For convenience.External generator, assembling is relatively simple, and rectifier and doing over again for adjuster repair more convenient, the radiating of rectifier
More preferably；But rectifier and adjuster need to assemble shield protection, the band more difficult implementation of pump motor.
In high-power generator, rectifier uses 12 tubular constructions more；Built-in rectifier, negative plate are fitted in end cap
On, end cap is helped to radiate, and positive plate is radiated using more toothings；External rectifier, existing structure are mostly rear fixed cover conducts
Negative plate or negative plate, which are fitted in rear fixed cover, to be radiated, and positive plate is radiated using die casting harden structure.When stator coil is using flat
During line stator, rear fixed cover is because stator heat transfer reason temperature is higher, and rectifies are generated heat on rectifier, and temperature passes
Lead, distribute poor, reach the junction temperature of commutation diode, so as to cause defective rectifier.
