Armature Reaction - SlideShare
The current flowing through the armature conductors creates a magnetic field, which is called as armature flux. This armature flux distorts and weakens the magnetic flux produced by the main poles. This effect of armature flux on the main flux is known as armature reaction. See more Consider a two pole generator on no-load. Thus, the current in the armature conductors is zero. Under this condition, there is only the main flux (φm) in the machine which is produced by the main poles. This main flux … See more This case shows the condition when the field current and armature currents are acting simultaneously. Hence, there are two fluxes inside the machine, one is produced by the main field poles of the generator and the … See more Now consider the armature carrying current with no current in the field coils. The direction of flux produced by the current in the armature conductors may be determined by cork-screw rule. Refer the figure, the … See more The armature reaction in a DC generator causes the following adverse effects 1. As the total field flux produced by each pole is slightly reduced, … See more WebJan 28, 2024 · It gives the relation between the generated e.m.f. E. on load and armature current. Due to armature reaction, the flux in the machine will be less than the flux at no load. Hence, e.m.f. E generated under load conditions will be less than the e.m.f. EO generated under no load conditions. el malei rachamim sheet music

WebDec 29, 2015 · The effects of Armature Reaction are as follows:-. Because of the armature reaction the flux density of over one-half of the pole … Web- The current drawn by the armature of DC motor is directly proportionalto torque. - Lenz’s law rule is used to determine the direction of rotation of dcmachines. - Compound dc motor at no-load it regulates highest speed. - The direction of this force is perpendicular to both the wire and themagnetic field in DC motor. WebOct 8, 2024 · A rotating armature and a stationary field (field windings) are always present in a DC generator. There are many coils in the rotating armature. Though increasing the number of coils lowers the output voltage ripples (pulsations), it … ford dickson
