In the modern world of engineering, every millimeter of space and every gram of weight matters. Original Equipment Manufacturers (OEMs) are constantly looking for ways to make their machines smaller, lighter, and more efficient—without compromising performance. At Innotec Power, we address this challenge through our frameless generator solutions, designed for seamless integration into OEM systems.
Unlike conventional generators, which come with their own frame and housing, frameless generators consist only of the core components—the rotor and stator. These are built directly into the customer’s equipment, eliminating unnecessary bulk while maximizing efficiency and flexibility. This approach offers unmatched advantages in industries where compactness, performance, and customization are key.
What is a Frameless Generator?
A frameless generator is essentially the heart of a generator—without the extra casing, bearings, or standalone frame. The design includes:
Rotor – The rotating component, fitted with high-performance permanent magnets (such as NdFeB magnets) and mounted directly on your system’s shaft.
Stator – The stationary part, made with precision-wound copper coils that interact with the rotor’s magnetic field to produce electricity.
When the rotor spins, the moving magnetic field induces an electrical current in the stator windings, creating clean and reliable power. Since these components are integrated into the host system’s structure, OEMs can take full control of the mounting, cooling, and overall mechanical design.
Why Frameless Generators are Ideal for OEM Applications
OEMs face several engineering challenges—limited space, weight restrictions, and specific performance requirements. Frameless generators from Innotec Power are the perfect answer to these challenges because they:
Fit Seamlessly Into Your System – Instead of adapting your design to fit our generator, we adapt our generator to fit your design.
Save Space – With no external frame, you can integrate the generator into your existing housing or gearbox.
Reduce Weight – Less hardware means a lighter system, improving efficiency and handling in vehicles and machinery.
Improve Thermal Management – The host machine’s cooling system can be used to keep the generator at optimal temperatures.
Allow Complete Customization – Shaft designs, bearing options, and mounting points can all be tailored to your needs.
Advantages of Frameless Generators
Frameless designs offer benefits that go beyond simply removing the housing:
1. Compact Design
These generators are ideal for space-constrained environments, such as aircraft, drones, marine vessels, and industrial equipment. The integration directly into your system means there’s no need for extra clearance.
2. Lightweight Construction
Without a separate frame, the weight drops significantly. In mobile systems like electric vehicles, aerospace equipment, and portable machinery, this directly translates to improved fuel or battery efficiency.
3. Better Heat Dissipation
Removing the enclosure allows for better airflow or integration into a liquid cooling loop. This results in higher continuous power output without overheating.
4. High Power-to-Weight Ratio
Frameless generators deliver substantial output compared to their size, making them a smart choice for applications where every gram counts.
5. Long Lifespan with Minimal Maintenance
Our frameless designs often use bearingless construction, which reduces wear and tear. Fewer moving parts mean fewer breakdowns and lower maintenance costs.
