If you are accustomed to high performance and superior quality and reliability of combustion engines OS, I'll be glad that you can now enjoy the same advantages for AC motors OS! They have been developed and designed to set a "gold standard" for electric cars as well, as is the rule for their methyl or gasoline counterparts. 80 years experience in OS developers ensures that even the new motors offer the same legendary quality and reliability.

OS brushless motors feature an integrated ventilation system, which increases their effectiveness and allows you to work at high current load and give better performance. A key element of this system is unique centrifugal fan which sucks air through a specially shaped air vents through the coil and around the magnet for considerably better cooling.

AC motors are robust OS restrictive risk of deformities, solid shafts of stainless steel stored in high-quality bearings, solid and secure rear mounting system with accurate propeller.

OS engines are due to its large twisting moment, suitable for large propellers without the need for a gearbox, which ensures high efficiency of the entire drive.
