Swedish environmental technology
NFO Drives is a Swedish clean tech company, which works with developing and manufacturing products that make electrical motors for machines, fans and pumps etc. more energy efficient. With our product – the NFO Sinus frequency inverter – the motor’s speed can be adapted to actual need, which means that you can save up to 70 per cent energy. Through reduced energy costs an investment in NFO Sinus pays for itself quickly – often within a year. Thanks to our patented technology, NFO Drives can offer an inverter without electromagnetic interference.

The patents
Ragnar Jönsson (M.SC.Eng.)at Ideon in Lund started in the middle of the 1980s researching different ways of better controlling electrical motors. Ragnar Jönsson’s work resulted in a number of patented inventions which made it possible to
1. Control the motor with full torque from the start and at low speeds
2 Control the electrical motor with a sinusoidal voltage which results in interference-free control.

The company
NFO Drives AB was started in 1996 to develop frequency inverters based on the new technology, under the name NFO Sinus®. The business was situated in Svängsta in Blekinge and the first product, a single phase inverter at 2.2 kW was launched on the market in 1998.

During the following years, the inverter was developed to provide increasingly higher power outputs and today the range includes a three phase inverter up to 15 kW. Throughout the years more patents have been obtained within the area of controlling electrical motors. 

All electronics are manufactured externally by partners. The final assembly of the inverter is carried out to some degree within our own company although OEM products are produced in large volumes by external contractors.

Our clients
Most of our current clients are in the Nordic countries although export sales have, during recent years, increased steadily, mainly within the EU. The automation of properties, with hospitals as the largest target group, has long been one of the most important areas, but interest in interference-free technology within industry and agriculture has grown. Among the company’s other clients, there are many well-known companies – read more about our clients>>

Contract with DeLaval
Our single biggest client is DeLaval International, with whom we have had a long-term OEM partnership since 2010. DeLaval is one of the world’s biggest manufacturers of products for milk production, e.g. milking machines and milking robots. The contract concerns developing and manufacturing inverters in several different power ratings. The inverters, which are called DeLaval NFO Drives, are included in DeLaval’s own product range and the first series was supplied in spring 2011.

The contract with DeLaval is the most important event in the history of the company and is estimated to boost the company’s turnover in the coming years. DeLaval’s decision to use NFO technology gives a quality approval which hopefully will help open doors to more OEM clients.
