The electric motor has had great success after developing the architect and professor of physics Moritz Hermann Von Jacobi in the year 1838, applied his theory to a boat, the energy required to make the electric boat motor function was powered by battery cells and this invention was so successful that transported 14 passengers and sailed to a 5.0 kilometers per hour.

In the year 1886 was scientist Werner Von Siemens managed to build a generator without using the permanent magnet, in that it was able to prove that the necessary tension to the magnetism could be removed from the rotor winding itself – part which is inside the motor and liable By making it turn – it was concluded that the machine could self excite.

The first Siemens engine had a power of about 30 watts and a rotation 1200 rotation per minute -RPM, the machine worked not only as a generator but also as an electric motor, which helped a lot in the growth of the industry. mro supply 6205 2RSJEM link checker
