The stator is the heart of the alternator, where electricity is generated. At EXEN, we use 100% pure copper windings, not copper-clad aluminum or lower-grade materials.
Why copper matters:
Higher conductivity: Copper delivers superior electrical efficiency compared to aluminum
Better heat dissipation: Copper handles high temperatures better, reducing the risk of overheating
Longer service life: Copper windings resist corrosion and fatigue, ensuring consistent performance over time
Some manufacturers cut costs by using aluminum or mixed materials—but that compromises output and durability. We don’t take shortcuts.
The rotor works together with the stator to generate the magnetic field needed for power production. Our rotors are manufactured with high-grade magnetic materials and undergo precision balancing to ensure:
Smooth rotation at high speeds
Reduced vibration and noise
Consistent voltage output across the RPM range
Every rotor is tested to meet OE specifications for fit, balance, and magnetic performance.
The rectifier converts the alternating current (AC) generated by the alternator into direct current (DC) that the vehicle’s electrical system can use. We use high-quality diodes and robust heat sinks to ensure:
Efficient power conversion with minimal loss
Protection against voltage spikes
Reliable performance under extreme temperatures
Our rectifiers are designed to withstand the electrical demands of modern vehicles, from advanced infotainment systems to safety features.
The voltage regulator ensures the alternator delivers a steady voltage—typically between 13.5V and 14.8V—to protect the battery and electrical components. Our regulators feature:
Precise voltage control for consistent output
Built-in protection against overcharging and short circuits
Durable construction tested for long-term reliability
Beyond the electrical components, we pay equal attention to structural integrity:
Aluminum housings provide lightweight strength and excellent heat dissipation
High-grade bearings are selected for smooth operation and long service life, even under heavy load conditions
