Irrigation and it’s Methods Irrigation may be defined as the science of artificial application of water to the land or soil. It is the replacement of rainfall with water from another source in order to grow crops. Several methods of irrigation are used today depending on the water availability and the type of crop to be irrigated. Some of these methods are: 1) Flood irrigation: In flood irrigation‚ a large amount of water is brought to the field and flows on the ground among the crops

DC motor is a mechanically commutated electric motor powered from direct current (DC). The stator is stationary in space by definition and therefore so is its current. The current in the rotor is switched by the commutator to also be stationary in space. This is how the relative angle between the stator and rotor magnetic flux is maintained near 90 degrees‚ which generates the maximum torque. DC motors have a rotating armature winding but non-rotating armature magnetic field and a static field
