Mechman Elite Series High Output Alternators

Mechman Elite Series High Output Alternators

The 6 Phase Advantage

Mechman Elite Series alternators employ cutting edge alternator technology not found in other aftermarket alternators. 6 phase hairpin stators make Elite Series alternators fundamentally more efficient than other aftermarket alternators. This technology and increased efficiency equates to incredible output at extremely low engine RPM, less energy wasted in the form of heat and more horsepower to the wheels. Also, because less heat is being generated, the internal components of Elite Series alternators last longer. This is especially beneficial on turbocharged and/or endurance racing vehicles with high engine compartment temperatures. All Elite alternators feature soldered stator and rectifier connections, with epoxy re-enforced stator connections, reducing the chance of vibration failures.

Mechman Elite Series High Output Alternators

High Pole Count

In addition, Mechman Elite Series units are built exclusively with precision balanced low-mass rotors that allow them to operate safely at shaft speeds of 20,000+ rpm. This high RPM capability, combined with excellent output at idle, gives the user a much broader operating RPM range, and more flexibility in the size of the crankshaft pulley used. A properly selected Elite Series alternator can even fix low voltage problems caused by using small diameter, or "underdriven" pulley ratios. The higher pole count in the rotor also results in less electromagnetic interference to cause problems with radios and other electronics.

Mechman Elite Series High Output Alternators

Twin Rectifiers

As a final precaution, Mechman Elite Series alternators are constructed with twin high efficiency cooling fans, and twin internal rectifier plates. While other high performance alternators have only one rectifier with 6 diodes, Elite Series units boast 12 press fit diodes with 300% more surface area to dissipate heat. These considerations to cooling airflow and heat dissipation make Elite Series high performance alternators the most durable aftermarket alternators you can buy. If you are experiencing pre-mature alternator failure, intermittent electrical accessory problems, or low voltage at any engine RPM, a Elite Series 6 phase alternator is the answer!
