2014 - Mazda6 - I-ELOOP

GENERATOR [i-ELOOP]

Purpose, Function

• With the adoption of i-ELOOP, a variable voltage type generator has been adopted which generates 12 to 25 V.

• 12 to 25 V is generated according to the vehicle conditions to charge the capacitor (i-ELOOP).

Construction

• The generator is installed on the engine left front side.

• The generator consists of the following parts:

  

  

• To handle a maximum of 25 V, the voltage resistance performance of the diode has been improved.

• With the adoption of i-ELOOP, an IC regulator with the following protection functions has been adopted.

Excess temperature protection function

• If the IC regulator reaches the specified temperature, the generator output current is restricted to suppress a rise in the temperature of the generator.

Excess voltage protection function

• If an excess excitation current control signal from the PCM is input, the generator output voltage is restricted to suppress application of excess voltage to the capacitor (i-ELOOP).

Excess-current protection function

• If the excitation current reaches the specified value, the excitation current is interrupted to restrict power generation by the generator.

• The initial excitation current to the rotors is supplied from the capacitor (i-ELOOP). When excitation current is supplied from the capacitor (i-ELOOP) and the generator begins generating electricity, the excitation current from the capacitor (i-ELOOP) is interrupted. After the generator begins generating electricity, the power generated by the generator is used for excitation current.
