The working principle of automobile alternator is that the stator and rotor of the generator are connected and assembled by bearings and end covers, so that the rotor can rotate in the stator and carry out the movement of cuts magnetic lines of force. thereby generating an induced electrical potential, which is extracted through the terminals connected in the loop, a current is generated.
The alternator uses the electromagnetic induction principle of cutting magnetic wire lines to induce electric potential and converts the mechanical energy of the main engine into electrical energy for output. The synchronous generator consists of two parts: the stator and the rotor. The stator is the armature that generates electricity and the rotor is the magnetic pole. The stator consists of an armature core, uniformly distributed three-phase windings, a machine base and an end cover. The rotor isusually hidden pole type and consists of excitation winding, iron core and shaft, retaining ring, center ring, etc.
The car's alternator is the car's primary source of power and is driven by the engine. In normal operation, it powers all electrical equipment, except the starter. In case of excess energy, it powers all electrical equipment. battery. When the alternator is running, do not use the fire test method to check whether it produces electricity, otherwise the diodes and electronic components may be easily damaged.
