A generator is a machine that converts mechanical energy into electrical energy
The energy conversion is based on the principle of the production of dynamically induced emf.
Whenever a conductor cuts magnetic flux, dynamically induced emf is produced according to faraday’s law of electromagnetic induction.
This emf causes a current to flow if the conductor circuit is closed.
Hence two basic essential parts if an electrical generator are:
1. Magnetic field
2. A conductor or conductors which can so move as to cut the flux.
Consider a single turn loop ABCD rotating clockwise in a uniform magnetic
field with a constant speed as shown in Fig. As the loop rotates, the flux
linking the coil sides AB and CD changes continuously. Hence the e.m.f.
induced in these coil sides also changes but the e.m.f. induced in one coil side
adds to that induced in the other.
Working of simple loop generator
(i) When the loop is in position no. 1 [See Fig. In above slide], the generated e.m.f. Is zero because the coil sides (AB and CD) are cutting no flux but are moving parallel to it
(ii) When the loop is in position no. 2, the coil sides are moving at an angle to the flux and, therefore, a low e.m.f. is generated as indicated by point 2 in Fig. In above slide.
(iii) When the loop is in position no. 3, the coil sides (AB and CD) are at right angle to the flux and are, therefore, cutting the flux at a maximum rate. Hence at this instant, the generated e.m.f. is maximum as indicated by point 3 in Fig in above slide.
(iv) At position 4, the generated e.m.f. is less because the coil sides are cutting the flux at an angle.
(v) At position 5, no magnetic lines are cut and hence induced e.m.f. is zero as indicated by point 5 in Fig. In above slide.
(vi) At position 6, the coil sides move under a pole of opposite polarity and hence the direction of generated e.m.f. is reversed. The maximum e.m.f. in this direction (i.e., reverse direction, See Fig. ) will be when the loop is at position 7 and zero when at position 1. This cycle repeats with each revolution of the coil.
