Types of Generator Heads
Brushless Generator Heads
Brushless generator heads are designed for high efficiency and lower maintenance compared to traditional models. They utilize rotors to generate power without the need for brushes, resulting in fewer moving parts and lower likelihood of breakdowns. These units are ideal for industrial and commercial applications, providing reliable power when it’s needed most. For instance, companies like PDG (Powerhouse Diesel Generators) offer a wide range of brushless alternators, making them a popular choice among contractors and businesses.
Synchronous Generator Heads
Synchronous generator heads operate at a constant speed, which makes them suitable for applications requiring stable voltage and frequency. These generators are often used in power plants and industrial settings where consistent power output is critical. Major manufacturers such as Stamford and Marathon provide high-quality synchronous generator heads capable of handling heavy loads, making them ideal for grid-connected applications.
Diesel Generator Heads
Diesel generator heads are renowned for their reliability and efficiency, especially in industrial settings. They are particularly effective for emergency backup power and in situations where access to fuel may be limited. With power outputs ranging from 20 kW to 2000 kW, brands like Cummins and Perkins dominate this segment, ensuring that businesses have the power they need during outages.
Natural Gas Generator Heads
Natural gas generator heads provide a cleaner alternative to diesel units. They are well-suited for commercial and residential applications, delivering power with a reduced environmental impact. Companies like Generac and Kohler manufacture high-quality natural gas generators that are popular for their cost-effectiveness and sustainability.
Portable Generator Heads
For those who need power on the go, portable generator heads are an excellent choice. These compact units are designed for easy transport and typically provide power output ranging from 1 kW to 10 kW. Brands like Honda and Yamaha are known for their portable generators, which are perfect for recreational use or emergency situations.
