MAGNETIC FIELD EXCITATION To manage the output voltage and look after the right conditions for your battery charging circuit excitation latest is adjustable. The controller is a new solid-state sensor that monitors the battery voltage. When it is small, the excitation circuit latest is increased. The excitation voltage is supplied by the stator rotating, the rectified by three LEDs (within the diagram are the decrease diode). They are quite small because the maximum excitation circuit current around 2 amperes. The controller acts as being a variable resistance, controlling the flow of current from the small diode in the actual energizing circuit. To excite the alternator is needed magnetizing winding, wound on the rotor. There are two systems of excitation with the alternator: and. In the vast most of excitation alternators to apply an extra three LEDs with a minimal forward current (approximately 2A).. The arrangement of most of these LEDs creates a half-wave rectifier. In the initial period a result of the residual magnetism in the rotor winding with the alternator voltage is brought on which after rectification with an additional LEDs flows from the coil causing an boost in magnetic flux, which implies that the actual increase in voltage. In the initial phase with the rotor work is also powered on the battery via a command lamp. This improves the characteristics with the start-up of the alternator, and sometimes even allows excitation with the alternator. Charging indicator must regularly be operational.
