The benefits of die-cast copper rotors

Improved motor performance

Thanks to its excellent conductivity, copper injected into the rotor, results in an efficiency increase which may range from 4.3 % by simply replacing the aluminum rotor by a copper rotor. This can increase up to 6.4 % if accompanied by a replacement optimized motor.

Return on Investment

Over a lifespan of ten years, the overall cost of an electric motor breaks down as follows : 2% for purchase , 3% for maintenance and 95% for power consumption.

The power consumption savings are due to the excellent conductivity of copper, allowing you a less than 7 months Return On Investment, thanks to the replacement of the aluminium rotor by a 3 kW copper rotor motor (Based on an annual use of 3000 hours).

Cost : 0,10 €/kWh – Europe

Improved power density

At the same power, the motor with a die-cast copper rotor will be less voluminous and will weigh and cost less than the aluminium motor rotor.

Reduced CO2 emissions

The use of a die-cast copper rotor instead of an aluminium rotor, results in decreased power consumption, reducing by about 3.8 tons of CO2 emissions during the lifespan of a 3 kw motor.

Based on : 3000 hours of use per year for 15 years. 0,46 kg of CO2 /kWh - Europe

Increased motor lifespan

The use of copper instead of aluminium helps lower the motor temperature by up to 30°C, thereby increasing the lifespan of the asynchronous motor.

Uses/Applications

Taking into account the energy efficiency of drive systems is now an essential part in many industrial sectors. Choosing copper rotors for asynchronous motors does increase performance.

High efficiency electric motors, gear-motors

Ventilation, cooling, cogeneration systems

Compressors

Heating pumps and circulators

INDUSTRIAL KNOW-HOW

As an industrial subcontractor, we study, industrialize, and produce die-cast copper rotors.

    Research & development

    Research & development

    FAVI has always considered R&D its priority . This is our largest department consisting of 31 engineers, technicians and draughtsmen.

    Typical projects :

    • Researching and developing specific alloys, that meet new technical or economic constraints, customer specifications or simply to open up new markets.
    • Developing innovative technologies in product processing.
    • Developing and optimizing products and processes, guarantees continuous improvement of product quality and economic performance.

    These innovations result from meeting and listening to our industrial clients and are linked to partnerships with ‘centres of excellence’ e.g. technical centres, professional schools, universities and trial laboratories.

    Product development

    As your industrial development Partner, our Design team proposes the optimization of your product, through die-casting, machining and assembling. All requirements and quality issues relating to the product and manufacturing process are taken into account, to guarantee top product preformance from Day 1 of production.

    Our Design office is experienced in the latest STATE OF THE ART Equipment :

    • CAD
    • Finite Elements Analysis
    • Rheology
    • Rapid prototyping in 3D, either machined from a block of the chosen metal, or from the initial samples.

    Product validation

    Our test laboratory validates products and materials :

    • Through material structural analysis and metallurgical testing.
    • Through physical static or dynamic testing,to validate product function and resistance.
    • Through specific bench testing on request.

    FAVI has been recognized in July 2015 as being able to carry out tests and provide results according to the car manufacturers’ required standards. This is known as ‘Self-Certification’.

    Production

    Pressure die casting has been our core industry since 1957. 

    It is through this expertise that we are able to inject and control pure copper at 1300°C.

    Up to now, we have produced more than 1,5 million die-cast copper rotors, whilst carrying out the entire manufacturing process : design, tooling, die-casting and machining.

Material and alloys

Cu97 pure copper

The copper we use to inject the rotors with has an excellent 97% IACS electric conductivity.

Our 'mini-factory' organization

At FAVI, our challenge is to place our customers at the centre of attention for each one of our employees, who organize production in our autonomous and independant mini-factories. Each mini-factory is dedicated to one customer or product and piloted by a team leader. All back-up services, such as Sales, QC and maintenance are closely integrated to favour reactivity, proactivity and communication.
