Ans: D Because, Motor is magnetically locked into position with stator, the rotor poles are engaged with stator poles and both run synchronously in same direction Therefore, rotor & stator mmf are stationary w.r.t each other. Q.37 In a capacitor start single-phase induction motor, the capacitor is connected (A) in series with main winding.

Air motor

The first mechanically powered submarine , the 1863 French submarine Plongeur , used a compressed-air engine. Musée de la Marine (Rochefort) . A pneumatic motor ( Air motor ) or compressed air engine is a type of motor which does mechanical work by expanding compressed air . Pneumatic motors generally convert the compressed air energy to mechanical work through either linear or rotary motion.

The vacuum impregnation technique is the latest technique to insulate the windings of stator and not used in rotors of any of the generators being used in the power plants nowadays. Firstly they alternate hollow and solid conductors. which involves the bending of the strips used in forming the coil of either rotor or stator. There are two solid .

Wind turbine designWikiVisually

Wind turbine design is the process of defining the form and specifications of a wind turbine to extract energy from the wind. A wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power, and other systems to start, stop, and control the turbine.
