The NorthStar Belt Driven Generator Head is a heavy-duty power generation component designed for users who need reliable, high-output electricity from an engine-driven system. With 10,000 surge watts and 9,600 rated watts, this generator head is built for demanding applications such as farm operations, construction sites, workshops, emergency backup systems, and custom generator builds.
Unlike portable generators that combine engine and alternator into a single unit, a generator head allows users to pair it with an engine of their choice. This flexibility is a major advantage for experienced users who want control over performance, fuel type, maintenance, and long-term durability.
This in-depth NorthStar belt driven generator head review explains how the unit works, what it can power, its electrical output configuration, and who will benefit most from this generator head.
What Is a Belt Driven Generator Head?
A belt driven generator head is the electrical power-producing component of a generator system. It is designed to be connected to an external engine via belts and pulleys. When the engine runs, rotational force is transferred to the generator head, which converts mechanical energy into electrical power.
The NorthStar belt driven generator head is intended for use with engines rated at 18 horsepower or higher, ensuring stable power output under heavy loads.
This type of generator system is preferred by users who:
- Already own a suitable engine
- Want a custom-built generator
- Need higher reliability than consumer-grade portable units
- Require long run times and easy engine servicing

- 40 amps at 240 volts
This high amperage capability makes it suitable for powering multiple devices simultaneously or handling heavy single loads. It is especially useful in applications where voltage drop and load stability are critical.
Engine Compatibility and Requirements
The NorthStar generator head requires an engine rated at 18 horsepower or greater. This ensures:
- Proper generator speed
- Stable voltage and frequency
- Reduced strain on the engine
- Longer service life for both components
Users can pair it with:
- Gasoline engines
- Diesel engines
- Propane engines
This flexibility allows users to select fuel types based on availability, cost, and runtime needs.
Belt Driven Design Advantages
The belt driven configuration offers several advantages over direct-coupled systems.
Key Benefits
- Reduced vibration
- Easier alignment adjustments
- Flexible engine mounting
- Lower stress on bearings
- Simplified maintenance
Belts also act as a mechanical buffer, protecting the generator head from sudden load changes or engine irregularities.
Build Quality and Construction
The NorthStar belt driven generator head is built for long-term use in demanding environments. Its heavy-duty housing protects internal components from dust, debris, and mechanical damage.
Internal windings and electrical components are designed for consistent output under sustained loads. This makes the generator head suitable for continuous-duty applications rather than short, occasional use.
Applications and Use Cases
Farm and Agricultural Use
This generator head is ideal for powering pumps, feed systems, and tools in agricultural settings where grid power may be unreliable or unavailable.
Construction and Job Sites
Contractors benefit from the high output and multiple receptacles, allowing several tools to operate simultaneously.
Home Backup Power
When paired with an appropriate engine and transfer system, this generator head can serve as a robust home backup solution for essential circuits.
Workshop and Industrial Use
Its stable power output supports sensitive equipment, motors, and high-demand machinery.
Installation Considerations
Installing a belt driven generator head requires basic mechanical knowledge.
Key considerations include:
- Proper pulley sizing
- Correct belt tension
- Secure mounting of engine and generator head
- Adequate ventilation
- Safe electrical grounding
Once installed correctly, the system offers reliable and efficient power generation.
Maintenance and Longevity
Maintenance requirements are minimal for the generator head itself.
Recommended maintenance includes:
- Periodic belt inspection
- Checking mounting bolts
- Inspecting electrical connections
- Keeping vents clear of debris
Because the engine and generator are separate, engine servicing does not require disturbing the generator head, simplifying upkeep.
