The three-phase generator – also known as “alternator” – is an induction machine operated as a generator that produces a speed-dependent three-phase alternating current using an electrical field. Since the electrical system is designed as a DC power system, this three-phase voltage must still be rectified. The control technology also comes into play: the voltage level should remain constant independently of the engine speed – the hybrid multifunction controller handles this.
In this educational system, a three-phase electric motor drives the compact alternator. The generator itself has power diodes on 4 mm safety sockets for measurement and interruption that are just as accessible as the three-phase winding.
The excitation current and the voltage can be captured on the connection plate, and connections are available
- to the battery monitoring (sensing)
- to the load and error detection, and
- to the rotation speed detection.
The generator’s output voltage can be led as a function of temperature or by the engine control unit.
In connection with lighting components, special high-current loads and a vehicle battery, the complete electrical system can be assembled!
