Land Rover Electrical alternator regulator Alternators generator OE LR029981 with highly conductive copper wire

Product Description:

Highly conductive alternator

OE NO.: LR029981 LR065867 LR124837

Applicable vehicle type: For Land Rover

The car alternator is the core power source of fuel-powered vehicles. Its task is to supply power to all electrical equipment in the vehicle (except the starter motor) when the engine is running (above idle speed), and to charge the 12V battery. Modern passenger cars have fully adopted the 'three-phase AC generator + built-in diode rectifier + electronic voltage regulator' scheme, outputting DC electricity of about 14V.

Product Attributes:

Alternator Finish: Aluminum

Alternator/Generator Rotation: Counterclockwise

New Or Remanufactured: New

Copper wire: High-quality, highly conductive

Characteristics of Different Types of Generators

• Permanent Magnet Alternator: This type of generator uses permanent magnetic materials such as neodymium-iron-boron as the rotor magnetic field source. Its main advantage is the elimination of brushes and slip rings, thus removing related wear failure points, resulting in high reliability and low radio interference. In particular, it has excellent low-speed power generation performance, making it very suitable for city buses with frequent start-stop operations. However, its magnetic field is not adjustable, and efficiency may decrease at high speeds.

• Water-Cooled Alternator: To solve the heat dissipation problem of high-power generators (usually over 2500W), some high-end vehicle models adopt water-cooling technology. It integrates the generator into the engine cooling system and uses coolant for heat dissipation, which improves heat dissipation efficiency. This helps the generator achieve higher power output without a significant increase in size, while also reducing operating noise.
