The Lycoming O-540 is a family of air-cooled six-cylinder, horizontally opposed fixed-wing aircraft and helicopter engines of 541.5 cubic inches (8.9 L) displacement, manufactured by Lycoming Engines.
A PTO at the rear end of a farm tractor A PTO (in the box at the bottom) in the center of the three-point hitch of a tractor. A power take-off or power takeoff (PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine.
Engines in this series also include the O-235 four-, O-580 six- and O-720 eight-cylinder engines, and the advanced turbocharged and fuel-injected 450 hp (340 kW) TIGO-541 variant of the venerable (carbureted) O-540. In the early 1980s, the general aviation market suddenly diminished and Lycoming's piston engine business was significantly impacted.
The 540 was powered by a Continental Motors Company 162-cubic-inch (2,650 cc) four-cylinder gasoline engine with a six-speed transmission, sharing the transmission with the larger 550. Although it was a utility tractor, the wheels could be adjusted in a manner similar to row-crop tractors, with power rear wheel adjust an option.
The term back electromotive force is also commonly used to refer to the voltage that occurs in electric motors where there is relative motion between the armature and the magnetic field produced by the motor's field coils or permanent magnet field, thus also acting as a generator while running as a motor. This effect is not due to the motor's ...

This, in turn, gives power to the motor at lower speeds. However, the focused flux density cannot rise about the limited residual flux density of the permanent magnet despite high coercivity and like all electric machines, the flux density of magnetic core saturation is the design constraint.
