ALTERNATORS

Alternators - 26759 AAK

DESIGN The alternator is a three-phase 12-pole synchronous self-excited generator with built- in rectifier and regulator and cooled by an external fan. Depending upon the purpose of the installation, various versions can be supplied: insulated, marine and other versions according to special requirements. APPLICATIONS High output power alternators to satisfy the needs for electrical energy in a wide range of applications: •for cars •for commercial vehicles •for heavy-duty applications •for special applications

Cooling An integral fan provides effective through coolingof the alternator. Two different fans are used depending upon the required direction of rotation.Also special fan for hand contact protection is avaible.

Rectifier A three-phase bridge circuit with press fit Zenerdiodes and excitation diodes provides D.C. output currents and excitation of the alternator. Zenerepower diodes provides protection of electrical loads on the vehicle against alternator overvoltages. Regulator Regulator with brush holder is fitted to the alternator.They are made in thin-film hybrid or microelectronic technology. With regard to the requirementsof the application they may be monofunctionor multifunction. The highest quality brushes ensurelong life of the alternator.
