Natural turbulence electrical power generator [PDF]
, 1980 An energy conversion apparatus is disclosed in which a stator, fixed to a watertight housing, is coupled to a rotor by a helical spring which suspends the rotor from the housing. Natural turbulence of a fluid, such as water or air, causes acceleration of

An Investigation on Stator Copper Loss by Using Different Stator Slot Size [PDF]
International Journal of Information and Electronics Engineering, 2013 The input power to an induction motor is in the form of three phase electric voltages and currents. The first losses encountered in the machine are I2R losses in the stator winding. The stator copper loss occurs when the stator windings is energized. This can be reducing by increasing the stator slot size.
