Switzerland- 09-09-2024- Connova AG, the specialist in composite solutions, announces the launch of its new CFRP sleeves designed to optimize electric motors' performance and durability. These high-performance Carbon Fiber Reinforced Polymer sleeves have been designed to further optimize both efficiency and service life for electric motors across such industries as automotive, aerospace, and renewable energy.

The introduction of CFRP sleeves into the market is going to mark a new era in the electric motor world, which guarantees lightweight, high-strength solutions to some of the most critical challenges of electric motor performance. These sleeves, popularly known as CFK bandages or tubes, come with unmatched benefits like reduced weight, improved mechanical strength, better thermal management, and higher overall efficiency of the motor.

Meeting the Growing Need for High-Performance Electric Motors

High-performance electric motors are in growing demand day after day as the world turns to more sustainable sources of energy and electric-powered transportation. Companies are keenly seeking advanced features that could maximize efficiency, minimize consumption, and elongate the life of electric motor parts. In this regard, CFRP sleeves from Connova will go a long way to provide a very efficient and durable solution regarding electric motors under demanding working conditions.

What are CFRP sleeves?

CFRP sleeves are light, cylindrical components made up of carbon fibers embedded in a polymer matrix. The fibers can be oriented in a fashion that would achieve the highest strength and rigidity possible with less weight. This results in a material much stronger than steel or aluminum but much lighter, and hence ideal for applications where weight reduction becomes critical.

The CFRP sleeves manufactured by Connova are to be wrapped around the rotors in electric motors for added structural strength with minimal additional weight. This leads to an improvement in motor output, energy consumption, and the lifetime either at high speeds or under heavy loads.

Key Benefits of CFRP Sleeves by Connova

The newly developed CFRP sleeves by Connova have several key benefits over conventional metal parts in electric motors, including but not limited to the following:

1. Superior Strength-to-Weight Ratio

The sleeves made of CFRP are famous for their excellent ratio of strength to weight. Carbon fiber is much lighter compared to traditional material, for instance, steel or aluminum, while the mechanical strength is much higher. In this way, the electric motors can operate more efficiently because less energy is needed to move the components of the motor.

2. Improved Thermal Management

Owing to the friction during operation, electric motors easily generate lots of heat. The CFRP sleeves of Connova are designed to allow high rates of dissipation for heat. This thereby aids thermal management in the motor. This enhances not only efficiency but also extends the useful life of the motor because there is a reduced possibility of overheating with potential mechanical failure.

3. Damping of Vibrations

In particular, in the case of electric motors, it is true that the vibrating behavior is often a key factor in the adverse performance of machines and may further lead to long-term damage. CFRP sleeves reduce the influence of vibrations on the motor components because they offer good vibration-dampening properties. This translates to smooth operation, less noise, and more service life.

4. Corrosion Resistance

Unlike traditional metal parts, CFRP sleeves have very high resistance against corrosion and degradation by environmental factors. This makes them ideal to be applied in tough environments, such as marine or industrial applications where the chance of moisture, chemical effects, or extreme temperatures exists.

5. Long Service Life and Less Maintenance

Due to its superior strength, CFRP sleeve-made electric motors have a lower frequency of maintenance and can last for a longer period. Reducing downtime and lowering the need for maintenance translates to reducing maintenance costs, thus making CFRP sleeves an effective option for industries that require electric motors for continuous operation.

Applications of CFRP Sleeves to Various Industries

This versatility can be further assisted and applied across a wide variety of industries with the help of Connova's CFRP sleeves, benefiting from the unique properties of carbon fiber composite technology.
Automotive

With increasing demand for electric vehicles around the world, there is growing pressure on automotive manufacturers to improve the efficiency of electric motors. Capable of assisting manufacturers in safely reducing weight from electric motors at very high power and reliability ratings, the CFRP sleeves from Connova make them ideal for applications within electric vehicles. In addition, the CFRP sleeves contribute to vehicle operation that's more efficient, quieter, and smoother because of their improved thermal management and vibration-dampening properties.

Aerospace

In the aerospace industry, where weight reduction is of the essence, CFRP sleeves mark a new frontier in electric motor-driven systems, including auxiliary power units and electric propulsion systems. Applications of CFRP sleeves will enable higher efficiencies in generating power and storing energy onboard an aircraft, which, in turn, significantly reduce fuel consumption and lower emissions.

Renewable Energy

Both wind and solar power generation systems utilize electric motors for efficient energy conversion into other forms. Connova's CFRP sleeves will enable renewable energy systems to run more efficiently for longer, hence guaranteeing reliable power generation with reduced maintenance.

Industrial Machinery

Another suitable application of CFRP sleeves is in industrial machinery where electric motors run under continuous heavy loads. With such high quality and resistance to corrosion, these sleeves can match harsh industrial environments, allowing the motors to run for a long time without frequently facing repairs or replacements.

Commitment to Innovation and Sustainability

Innovation and sustainability are cornerstones in everything that we do at Connova AG. Our CFRP sleeves represent a new generation step in carbon fiber, offering industries a greener and more efficient solution to electric motor performance. This brings down energy consumption by electric motors and prolongs their service life, contributing positively to the overall environmental footprint of many industries.
