Introduction
Automotive generators are necessities of car assembly and main power supplies of car electric systems, which is an important and indispensable part of automotives. During normal work, an automotive generator powers all electric equipments (except starters), charges accumulators and replenish electric energy consumed by accumulators. Automotive generators, with high technology and high difficulties, are essential products for cars’ fast and reliable starts and normal operation, which is a significant symbol of cars.
Application
Automotive permanent magnet AC generators employ the newest international magnetically inductive materials----neodymium magnet as magnetic fields. Comparing with winding excitation generators, they don’t have claw poles and magnetic yoke casted by black metals; don’t have excitation coils would with enameled wires; don’t have electric blushes and collecting rings. They can meet high standards and requirements of modern cars under various circumstances, which have high efficiency and reliability, without carbon blushes. Without interference on on-boarded electrical appliances, they reduce charging and discharging frequency and lengthen service life of storage batteries. Under the circumstances of no storage batteries or batteries without electricity, cars can start running as well with high power rate. Due to special designs, they are widely recognized and used by urban public transportation system. Automotive permanent magnet generators are successfully used in diversified kinds of gasoline engines and diesel engines of cars, which are more applicable for urban buses, mining machinery and municipal road construction machines.
Composition
Automotive permanent magnet generators are mainly composed of fan covers, regulators, rear covers, stators permanent rotators, front covers, bearings and belt pulleys.
Characteristics
1. Automotive permanent magnet generators don’t need accumulators to supply power, because their stators are permanent magnets that need no excitation magnet electric current. They can generate electricity by rotating starters, which save energy. Their output power is as twice as that of excitation magnetic generators in the same sizes.
2. The generators have excellent power supply performance in low speed and low small voltage regulation factors.
3. They have strong environmental suitability. Without excitation magnet windings and carbon ring structures, they can work under harsh conditions.
