Alternator
This week in class we disassembled an alternator the charging system for cars. We strip down to obtain reading for the five main components.
Rotor
The rotor is the center point in the alternator which is the main turning shaft. We measured the resistance which was around 0.00 ohms.This means that ther is a low resistance that can allow more current to flow through the shaft.
Voltage regulator
The voltage regulator is basically a gate it shut off the voltage supply to the battery if it surpasses a curtain voltage around 14.1 and keeps your battery from being over charged and over heated
Stator winding
The stator is basically a stationary winding which starts to spin when it is energized by AC current. The windings are well insulated from the frame and have a very low resistance which allows more current to flow through.
Rectifier
The rectifier is the part were the AC voltage is converted to DC voltage because in automotive we only uses direct voltage.we found out on the rectifier 3 of the plates gave us a reading around 0.560 except for 1 which gave a reading of infinite.
Brush
The brushes ride on the slip rings of the rotor and connect a switch to the battery. When the circuit is a closed loop the energy creates a magnetic field to provide power to the rotor. So I believe
a good reflection on alternators-- but what results did you record when testing the alternator and what was your conclusion about the alternator you worked on ?
ReplyDeleteyour Battery posting is too light-- very little information and no record of what you did to test your battery in practical classes
cool will post more on battery blog
