Brief History of Motor development:

1.182 Tesla discovered the magnetic effect of the current, and then ampere established the Ampere law by summing up the current in the magnetic field by the mechanical force.

Tesla invented the first motor model for 2.1821 years.

For 3.1831 years, Faraday invented the world's first truly electric motor, the Faraday disc generator, using electromagnetic induction.

In the summer of 4.1831, Henry improved Faraday's motor model to become the first oscillating motor.

For 5.1832 years, Sturgeon invented the commutator, which improved Henry's oscillating motor and made the world's first rotating motor capable of producing continuous motion.

6.1834 years, Germany's Jacobian in two U-type solenoid, 16 arm wheel, each arm with two rod-type magnet, after power, Rod magnet and U-shaped magnets between the attraction and repulsion, driving the axle rotation.

For 7.1882 years, Germany transmitted 2-kilowatt DC power from the Misbaha hydropower station to Munich via 57-kilometer 1500~2000 kv wires, proving the possibility of HVDC transmission over long distances.

The emulation occurred due to an unknown error. will be done together with others and expected to be made up tomorrow.
