time and torque is obtained from the first spin for the whole life of the vane – a very rare and significant achievement and completely changes the operating profile of Magnevane motors ,” says Magnevane CEO Gareth Rees .
With this design , the company has achieved a 50 % to 60 % increase in efficiency against the current leading air motors in the market . In addition , since the vanes are always pressed against the housing and Vesconite Hilube is a superior product , the company is achieving a 300 % longer maintenance life cycle , with consistent performance attained over this time .
Rees reports that the company investigated bonded vanes but , since these wear out quickly , they reduced the life of the motor by 50 % to 70 % and Magnevane concluded that Vesconite Hilube is the best performing vane material that it has tried to date . By fitting Vesconite Hilube vanes , the company has two benefits : the motor runs longer with a better wear life and the efficiency of the motor is increased .
Magnevane ’ s first tooling application to use their patented motors , the chainsaw , has been in development and testing for several
years , and has already proved itself in the harsh South African mining environment and is now ready to be introduced to other mining countries , with Portuguese-owned Magnevane expecting to obtain a significant share of the 15 000 unit underground South African chainsaw market within three years .
The company is also developing more end-to-end applications , such as displacement pumps and compressors . Magnevane continues to work with Vesconite Bearings on these applications , including the Hitemp160 polymer that is heat resistant to 160 º C and is a prime candidate for the vane material of the Magnevane displacement pumps .
Besides manufacturing products , the Magnevane sees itself as a research and development company with intellectual property , including its air motors with magnets , which it is prepared to licence to original equipment manufacturers .
“ This is the best air motor in the world - with the best vanes ,” enthuses Rees , “ and will move the dial on pneumatic operating costs across industry ”.
