Electric Motor

The electric motor is a device employed for transforming energy into mechanical energy. We know it to turn machinery and various appliances.
We have already seen the generator convert mechanical energy into electric energy. Now, the process ia reversed. It is electricity that is supplied to the machine and it is motion that we obtain. From all that has beed said in the previous articless about our getting magnetism from electricity and about the generation of electric current by using magnetism, it is obvious that generators and motors are similar in certain respects. There is certainly some difference in detail but in both of them we find an armature with windings, a commutator and brushes combined with an electromagnet for producing the magnetic field. However, in an electric motor, one shunt winding is not sufficient and a second one called a series winding should be added. “Why is it necessary?” one might ask. The fact is that the motor should have a powerful effect at the very moment when the current is switched on, as for instance, in an electric tram or a train. A very strong magnetic field is needed to obtain a so-called powerful starting torque. This is achieved by adding a series winding to the magnetic coils. It is connected not in shunt with the armature but in the series with it. Thus, all the heavy starting current, passing through the armature winding, now passes through the series field coil and provides a strong field necessary for starting, the shunt field winding providing the running conditions.
The facts you have been given above illustrate the wide use of transformers and their great importance.
Another alternating-current system of transmission and distribution is shown in Fig.9. You are asked to follow the whole process, that is, to describe it from beginning to end.
